Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1a is a flowchart of a theme switching method in a first embodiment of the present invention, where the method may be applied to a case of switching a theme by an application in a mobile terminal, and the method may be performed by a theme switching apparatus provided in the embodiment of the present invention, where the apparatus may be implemented in software and/or hardware, and may be generally integrated into a computer device, for example, a terminal device, etc. The method of the embodiment specifically comprises the following steps:
S110, when a theme switching instruction is received, a theme switching request is sent to a target user interface control through a theme management component, wherein the theme switching request comprises a theme configuration file to be switched, and the theme configuration file is updated in real time through a server.
The theme switching instruction is used for controlling the client to switch the theme, and can be an instruction generated according to user input operation or an instruction sent by the server. In particular, theme switching refers to changing a style of a user interface, for example, adjusting a layout, a color, a font, and the like of the user interface.
In the embodiment of the invention, the client can be provided with a plurality of user interfaces, different user interfaces can display different contents, and the user interfaces can be switched. The user interface comprises a plurality of visual elements, and a user can interact with the visual elements to realize the operation of the user interface.
The visual element may refer to a user interface control, specifically, the user interface control is used for at least one of displaying in a user interface, receiving a value input by a user, interacting with the user, responding to a user operation, and the like. By way of example, the user interface controls may include: buttons (uibuton), labels (UILabel), and input boxes (uintextfields), etc., and accordingly, user interface control theme switching may include changes in text size, text style, and background color, etc.
The theme management component may traverse and obtain all of the user interface controls and filter them to obtain at least one target user interface control. The number of target user interface controls is typically at least one. The screening method may be to screen out a user interface control containing the subject information.
Optionally, the operating system of the terminal device is an IOS system. Optionally, the target user interface control includes: uire response object, uire response object sub-class object, cayer object and cayer object sub-class object.
The uiring response is a class under the IOS system, and is used for defining a group of interfaces for objects needing to respond to and process events, in particular, when a user triggers a button on a user interface, a button trigger event is correspondingly required to be generated, and corresponding processing is performed to respond to the user. The uiiresponder object subclass object may refer to an object that inherits the class of uiiresponder.
The layer is a layer, specifically a rectangular area with visible content on the user interface, in which a drawing can be performed to display visual effects of controls, images or text. Virtually all user interface controls need to be displayed in the view, specifically, the user interface controls are drawn in the layers, and the system copies the layers to the user interface to display the content drawn on the layers. The CALayer object subclass object may refer to an object inheriting a class of CALayer.
By limiting the scope of the target user interface control to: the UIREspoonder object, the UIREspoonder object sub-class object, the CALayer object and the CALayer object sub-class object can completely contain the related controls of the user interface, and the coverage of the target user interface control is increased, so that the user interface control range of theme switching is increased, and the accuracy of theme switching is improved.
The theme management component is used for managing the user interface control, and is mainly used for managing whether the user interface control executes theme switching operation or not.
The theme switch request is used for the theme management component to inform each target user interface control to switch the theme. The theme switch request is sent by the theme management component to each target user interface control. For example, the theme switch request may include a historical theme profile and a theme profile to be switched. The theme configuration file to be switched is a new theme configuration file. The historical theme profile may be a theme profile that is currently in use.
The theme configuration file is used for determining the theme of each target user interface control, and specifically may include information about the switched theme, for example, the color of a configuration button in the theme configuration file is red, and correspondingly, after the button performs theme switching, the color of the button is adjusted to be red.
The theme configuration file to be switched is used for indicating each target user interface control to carry out theme adjustment. The theme profile to be switched may include theme information adjusted by the target user interface control.
A plurality of theme configuration files are stored locally, and the theme configuration files to be switched can be determined according to theme switching instructions. The theme configuration file is updated in real time through the server, which indicates that the theme configuration file is updated at any time through the server, and the updating period of the user interface is greatly shortened.
S120, when a theme switching request is received through the target user interface control, requesting target switching component information from the theme management component, wherein the target switching component is matched with the target user interface control.
Requesting, by the target user interface control, target switching component information from the theme management component when receiving the theme switching request may include: and when the target user interface control receives the theme switching request, if the theme switching request determines that the theme switching condition is met, the target user interface control requests the theme management component for the target switching component information. If it is determined that the theme switching condition is not satisfied, the target switching component information is not requested from the theme management component. Specifically, the target user interface control may determine that the theme switching condition is satisfied when it is determined that the history profile is the same as the currently used (or activated) profile according to the history profile in the theme switching request.
The target switching component information is used by the target user interface control to invoke the target switching component, and may refer to interface information of the target switching component, for example. The target switching component is used for switching the theme of the target user interface control.
Different target user interface controls differ in the method or attribute of theme switching. Thus, a different switching component needs to be invoked for each target user interface control to effect the corresponding theme switching. The user interface control can query the corresponding relation between the pre-stored target user interface control, the theme information and the switching component according to the theme information to be switched in the theme switching request, and determine the matched switching component.
The theme management component stores target switching component information, so that the switching components can be managed uniformly.
The target user interface control may store identification information of the switching component required by the target user interface control, and obtain, through the theme management component, target switching component information matched with the identification information. And the matched switching component is determined through the target user interface control, the switching component information is directly requested to the theme management component, and the theme management component only needs to inquire the target switching component information and feed back the target switching component information, so that the data volume processed by the theme management component can be reduced.
Optionally, the number of the target user interface controls includes at least two, and the number of the switching components matched by the at least two target user interface controls includes at least two.
By configuring at least two target user interface controls and at least one switching component for each user interface control, theme switching can be accurately performed for the user interface controls, and flexibility and accuracy of theme switching are improved.
S130, calling a matched target switching component through the target user interface control according to the target switching component information fed back by the theme management component.
The target user interface control does not have the function of theme switching, and the theme switching of the target user interface control can be realized by calling the target switching component.
And S140, performing theme switching on the target user interface control through the target switching component according to the theme configuration file to be switched.
The object switching component is configured to modify a parameter value of a parameter in the object user interface control to a parameter value that matches the theme configuration file, for example, a shape parameter of the object user interface control is rectangular, a shape parameter in the theme configuration file is elliptical, and the theme switching refers to modifying the shape parameter of the object user interface control to be elliptical.
Optionally, before sending the theme switching request to the target user interface control through the theme management component, the method further includes: and inquiring at least one user interface control which is currently operated and matched with the theme switching instruction through a theme management component, wherein the at least one user interface control is used as a target user interface control.
The currently running user interface control may refer to a user interface control displayed on a display screen. It should be noted that the currently running user interface control may also refer to a currently activated user interface control, and in addition, there are other limitations, and in contrast, embodiments of the present invention are not limited in detail. The currently non-running user interface controls may not require theme switching and may do so when needed for display.
The user interface control matched with the theme switching instruction refers to a user interface control containing theme information. The user interface control containing the theme information indicates that the user interface control is different with the theme, and the corresponding visual effect or function is different, that is, the user interface control containing the theme information is changed with the theme switching. In general, user interface controls that do not contain theme information do not change as the theme changes. Eliminating user interface controls which do not contain theme information can reduce the number of user interface controls for theme switching.
As illustrated in fig. 1b, the theme switching method may include:
s101, inquiring at least one user interface control which is currently operated and matched with the theme switching instruction through a theme management component, wherein the at least one user interface control is used as a target user interface control.
S102, sending a theme switching request to each target user interface control through the theme management component.

S104, calling a matched target switching component through the target user interface control according to the target switching component information fed back by the theme management component.
S105, performing theme switching on the target user interface control through the target switching component according to the theme configuration file to be switched.
At least one user interface control which is currently operated and matched with the theme switching instruction is used as a target user interface control, so that the target user interface control is screened, the number of the user interface controls for theme switching is reduced, and the updating efficiency of theme switching is improved.
According to the embodiment of the invention, the theme management component is configured, the theme switching request is generated according to the theme configuration file updated by the server in time and is sent to the target user interface control to control the theme switching of the target user interface control, the target user interface control obtains the matched target switching component through the theme management component and invokes the matched target switching component, and the theme switching operation of the target user interface control is realized through the target switching component, so that the theme switching of the user interface is realized, the problems that the user interface can only be updated in a version period and the code modification amount of the theme switching of the user interface is large in the prior art are solved, the development cost of the user interface of an application program can be reduced, and the updating efficiency of the user interface is improved.
Example two
Fig. 2a is a flowchart of a theme switching method in a second embodiment of the present invention, where the theme switching is performed on the target user interface control by the target switching component according to the theme configuration file to be switched, based on the foregoing embodiment, and is specifically: performing switching verification on the target user interface control through the target switching component, wherein the switching verification comprises a switching method and attribute accessibility verification and/or topic information existence verification; and when the verification is passed, performing theme switching on the target user interface control through the target switching component according to the theme configuration file to be switched.
Specifically, the method of the embodiment specifically includes:
and S210, when a theme switching instruction is received, a theme switching request is sent to a target user interface control through a theme management component, wherein the theme switching request comprises a theme configuration file to be switched, and the theme configuration file is updated in real time through a server.
Reference may be made to the description of the above embodiments for a non-detailed description of the present embodiments.
As shown in fig. 2b, before receiving the theme switching instruction, the method may further include:
S201, starting the client.
A client may refer to an application where the functionality of the application includes, but is not limited to, live, video, gaming, billing, financial, sports, and the like.
The method can also comprise the following steps when the client starts up: and loading all the user interface controls displayed on the current user interface into the memory, namely creating user interface control objects.
S202, the client acquires a user interface control through a theme management component.
The theme management component may obtain all user interface controls currently running by traversing the created user interface control objects. When the user interface is switched, the user interface control displayed on the original user interface is released from the memory, and the user interface control displayed on the new user interface is loaded in the memory. Correspondingly, the theme management component can correspondingly release the user interface control of the history operation by traversing the user interface control object in the memory, and acquire all the user interface controls of the current operation, so that the memory leakage is avoided.
S203, the client initializes the switching component.
Initializing the switch component may refer to loading the switch component in memory. It should be noted that all the switching components may be initialized, and only the switching components that match the currently running user wiring control may be initialized. Optionally, the client acquires and initializes a switching component matched with each user interface control.
S204, the client updates the local topic configuration file.
Specifically, the updating of the local topic configuration file by the client may include: when the client is started each time, the client requests the server for updating, and receives an updated configuration file fed back by the server; or the client requests the server for updating according to the set period and receives the updated configuration file fed back by the server; or the server transmits updated configuration files to the client according to the set period; or, when receiving the update instruction of the technician, the server issues the updated configuration file to the client, and in addition, the server may also set according to the actual situation, which is not particularly limited in the embodiment of the present invention.
The client side obtains a local theme configuration file through the theme management component, generates a theme configuration file update request and sends the theme configuration file update request to the server. And the server feeds back the updated theme configuration file according to the theme configuration file updating request. And the client updates the local theme configuration file according to the received updated theme configuration file. The theme profile update request may include identification information of an updated theme profile or identification information of a locally latest theme profile, and the server may determine and acquire the updated theme profile according to the identification information.
When the client is started, the user interface control is obtained, the switching component is initialized, and the theme configuration file is updated, so that the client can finish the preparation work of theme switching, and the accuracy of theme switching is improved.
S220, when a theme switching request is received through the target user interface control, requesting target switching component information from the theme management component, wherein the target switching component is matched with the target user interface control.
S230, calling a matched target switching component through the target user interface control according to the target switching component information fed back by the theme management component.
S240, performing switching verification on the target user interface control through the target switching component, wherein the switching verification comprises a switching method and attribute accessibility verification and/or topic information existence verification.
The switching verification is used for judging whether the user interface control can perform theme switching. In practice, the switching verification is used for judging whether the theme switching of the user interface control is abnormal, namely, the security check is performed, and in particular, is used for judging whether the switching method and the attribute in the user interface control are accessible and whether the theme information exists.
The switching method and the attribute accessibility verification are used for verifying the method for switching the theme, and whether the switching attribute can be accessed, in particular, whether the method for verifying the theme switching and the switching attribute can be modified. If both the switching method and/or the switching attribute are accessible, the verification is passed. If the switching method and/or the switching attribute cannot be accessed, verification fails, which indicates that the method and the attribute of the target user interface control cannot be updated, and theme switching cannot be performed. The method is exemplified by the setTitleContor in UIBtton, the for State method, and the attribute is the color attribute in CALayer. In addition, there are other methods or attributes to which embodiments of the present invention are not limited.
In particular, the switching methods and attributes may include methods and attributes associated with the theme profile. For example, the theme profile is used to modify the original button function (e.g., change the shape of the title after clicking) to change the color of the title after clicking, where the accessibility of the method of changing the color of the title (e.g., setTitleContolor: for State) needs to be determined first, and if accessible, it indicates that the method can be modified. Accordingly, if the attribute is accessible, information such as an attribute value indicating the attribute may be modified.
The topic information presence verification is used to verify whether topic information is contained in the target user interface control. If the user interface control contains theme information, the user interface control is indicated to be different along with the theme, and the corresponding visual effect or function is different, namely the user interface control containing the theme information is changed along with theme switching. In general, user interface controls that do not contain theme information do not change as the theme changes. If the target user interface control contains subject information, the verification passes. If the theme information does not exist in the target user interface control, verification fails, and the method and the attribute of the target user interface control cannot be updated, namely theme switching cannot be performed. The information in the user interface control can be judged whether to belong to the theme information or not through the theme identification.
It should be noted that, if the foregoing filtering operation of the user interface control is performed, that is, the user interface control matched with the theme switching instruction is used as the target user interface control, at this time, the theme information presence verification operation may be omitted, or may be selected not to be omitted, so as to further ensure that the target user interface control has the capability of theme switching.
Optionally, the switching component includes a general switching component for performing a theme switching operation for a plurality of user interface controls of the same type, and a specific switching component for performing a theme switching operation for user interface controls that satisfy a theme-specific control condition.
Generally, the switching methods of the partial theme information of the plurality of user interface controls are the same, and meanwhile, the switching methods of the partial theme information of the user interface controls are different. Theme information that can use the same switching method can be implemented using the same switching component, and theme information that uses different switching methods requires additional reconfiguration of the adaptive switching component implementation. Thus, the generic switching component and the specific switching component can be configured accordingly.
The generic switching component may perform theme switching for as multiple user interface controls and the specific switching component may perform theme switching for only a few user interface controls. The theme of one user interface control can be switched, and a plurality of switching components can be simultaneously invoked, wherein the plurality of switching components comprise a general switching component and/or a specific switching component.
The user interface controls of the same type may mean that theme information contained in the plurality of user interface controls may be subjected to theme switching by using the same switching method.
The theme-specific control condition is used for judging whether the switching method of the theme information of the user interface control is the same as the switching method of the theme information of other user interface controls.
The user interface control meeting the condition of the theme-specific control may be that a switching method of theme information of the user interface control is different from a switching method of theme information of other user interface controls, that is, the theme information contained in the user interface control cannot be subjected to theme switching by adopting the same switching method as that of other user interface controls.
The functions and the number of the specific switching components are determined according to the theme information of the user interface control, and can be specifically set according to actual conditions, so that the embodiment of the invention is not particularly limited. At the same time, the particular switching component may be updated in accordance with the update of the user interface control.
By configuring the universal switching component, the theme switching of the same mode can be realized for a plurality of types of target user interface controls, and configuring the specific switching component, the theme switching can be realized for the specific target user interface control, the repeated configuration cost of the switching component can be reduced, and meanwhile, the theme switching can be independently realized for the specific user interface control, so that the theme switching accuracy is improved.
And S250, when verification is passed, performing theme switching on the target user interface control through the target switching component according to the theme configuration file to be switched.
And when the verification is passed, indicating that the target user interface control can perform theme switching. And after the verification is passed, performing theme switching on the target user interface control, ensuring successful realization of theme switching, and avoiding abnormal situations.
Specifically, as shown in fig. 2c, after the target user interface control invokes the matched target switch component, the method may further include:
s211, the target switching component judges whether the switching method and the attribute of the matched target user interface control are accessible, if so, S212 is executed; otherwise, S214 is performed.
S212, the target switching component judges whether the matched target user interface control contains theme information or not, and if so, S213 is executed; otherwise, S214 is performed.
And S213, the target switching component performs theme switching on the matched target user interface control.
And S214, the target switching component does not subject to switching on the matched target user interface control.
According to the embodiment of the invention, the target user interface control is verified, and when verification passes, the main body switching is executed, so that the user interface control can be ensured to accurately and safely realize the theme switching, and the error of the theme switching is reduced.
