Detailed Description

The embodiment of the invention provides a method and a device for controlling real-time refreshing of content, which are used for carrying out real-time displaying and refreshing of data content on a dynamic interface and ensuring the display efficiency of the interface.

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a flowchart of an embodiment of a method for controlling real-time content refresh according to an embodiment of the present invention includes:

s101, creating a single case, adding a timer in the single case, and setting the callback of the timer;

and the setting of the callback of the timer comprises setting the time of each callback of the timer, and setting the timer to repeatedly execute the callback operation.

The timer is removed after the timer is added, and the specific implementation process is as follows: defining a timer variable, acquiring a timer through the attribute variable, calling a method invalid to the timer when detecting that the current display interface is removed, pausing the timer, and setting the timer to nil, namely removing the timer from the program. The timer is removed to avoid the problem of memory explosion, and effective management of the timer can be realized.

S102, defining a function variable, setting the function variable to perform specific change when the timer is reset every time, and setting corresponding display content according to the characteristics of the current function variable;

defining a large natural number, such as 10000, wherein the function variable will increase or decrease regularly during each callback process by fixing the timer, obtaining the value of the current function variable, dividing the value by a specific number, such as natural numbers of 2 or 3, judging whether the integer division can be performed, and respectively setting the display content which can be performed with the integer division and the display content which can not be performed with the integer division according to whether the integer division can be performed.

S103, assigning the display content to the singleton attribute, and refreshing the display content of the current interface when the singleton attribute is detected to be changed.

The method comprises the steps of obtaining a created singleton object, adding an observer to the object, setting observed attributes, wherein the attributes can be one or a plurality of attributes, setting an attribute value change range of the attributes, judging whether the changed attribute values are preset observed attribute values or not after the display content is assigned to the attribute values of the attributes, and displaying data contents such as texts, pictures and the like contained in the attribute values if the changed attribute values are the preset observed attribute values.

Preferably, steps S101, S102 and S103 may all be performed on the IOS system.

With reference to fig. 2, the display content of the current interface is displayed through the area B, and the operation of adding and removing the timer is performed along with the disappearance and appearance of the area a, because the area a is in the dynamic change process, there is a technical difficulty in directly performing dynamic display of the content in the area a, and it cannot be guaranteed that the display content can be refreshed in real time. As can be seen from the embodiment illustrated in fig. 1, in the embodiment of the present invention, the timer is added by creating a single instance, and because only one part of the lifecycle exists in the single instance, there is no need to repeatedly add the timer as the conventional UI appears with the disappearance of the interface, which can ensure that the timer is added only once, save the storage space, and ensure the timing and regularity of the interface refresh. Meanwhile, in S103, attribute change is observed by adding KVO, and the KVO observes the attribute value very quickly, so that the attribute change can be monitored immediately after the callback function of the timer assigns the attribute, and the real-time performance of interface content refreshing is further ensured.

Based on the embodiment shown in fig. 1, further, a method for controlling content real-time refreshing in the embodiment of the present invention is described in detail in conjunction with a program execution flow, as shown in fig. 3,

in S301, a single instance is created and named dynannualtwomanager, and a timer is defined in the single instance and the following method is added to the timer:

defining a timer variable countDowntimer, triggering a method internal fireTimer of the timer variable, wherein the method is mainly used for judging whether the countDowntimer exists or not, if not, creating a timer by using a method for creating the timer, and the method for creating the timer is timeWithTimeInterval. Meanwhile, the timer is added into the system running cycle, and the addition of the timer into the running cycle can ensure that the timer is not interfered by other events.

Meanwhile, an attribute is added in a singleton, and the attribute value is set to shouldShowMval.

In S302, the setting of the callback of the timer includes setting the callback time of the timer and repeatedly executing the setting of the timer.

In S303, the timer is called back to the function oncountdown normaltime fire, here set to 1 second, every time the timer is called back, the showTime value changes, here set to minus one.

In S304, according to the feature of the current showTime value, for example, according to whether the set showTime is divisible by 3, the corresponding display content is set, and if yes, the display content is set to a, and if not, the display content is set to B.

In S306, adding KVO and observing attribute changes during interface initialization and data configuration, specifically, the following steps:

and acquiring the created singleton object by using the shareManager, taking the object, adding an observer to the singleton object by using the addObserver, and setting the attribute of the observed object. Here, the observed attribute is shouldShowMval, which can be defined by itself, and the number of observed attributes is not limited. Meanwhile, the change range of the attribute is set, the old attribute value of the new attribute value is set to be observed in the invention, the new attribute value is set through a parameter NSKeyValueObservingOptionNew, and the old attribute value is set through a parameter NSKeyValueObservingOptionOld.

When the attribute value shouldShowMval changes, a function observeValueForKeyPath callback is triggered, and parameters of the function include: observed property value keyPath, dictionary type change, with new and old values in the change. And comparing whether the keyPath attribute value is the attribute value to be observed or not, if so, acquiring the display content in the new value, and further displaying the refreshing content of the interface.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

The foregoing mainly describes a method for controlling content real-time refresh, and a detailed description will be given below of an apparatus for controlling content real-time refresh.

Fig. 4 is a block diagram illustrating an embodiment of a device for real-time refreshing of a control interface according to an embodiment of the present invention, including:

the creating unit 41: the method comprises the steps of creating a singleton, adding a timer in the singleton, and setting a callback of the timer;

the control unit 42: the function variable is set to carry out specific change when the timer is reset every time, and corresponding display content is set according to the characteristics of the current function variable;

the refresh unit 43: and the display content is assigned to the singleton attribute, and when the singleton attribute is detected to be changed, the display content of the current interface is refreshed.

Further, the above apparatus further comprises:

the removing unit 34: the method is used for defining an attribute variable, acquiring a timer through the attribute variable, calling a method for disabling the timer when detecting that the current display interface is removed, and removing the timer.
