Slightly inspired by Google's material radio button.

The clip below has 3 sections: full speed, 25% and 10%, but after converting it to GIF, it actually made it longer, so the 10% part takes a really long time.Here's an mp4 link; try with Chrome if Safari doesn't work - for me it doesn't.

NOTE:These instructions are intended for usage on Xcode 11 and higher. Xcode 11 is the first version of Xcode that integrates Swift Package Manager and makes it way easier to use than it was at the command line. If you are using older versions of Xcode, we recommend using CocoaPods.

1. Go to File > Swift Packages > Add Package Dependency...
2. Paste the URL to theLTHRadioButton repo on GitHub (https://github.com/rolandleth/LTHRadioButton.git) into the search bar, then hit the Next button:
3. Select what version you want to use, then hit next (Xcode will automatically suggest the current version Up to Next Major).
4. Select theLTHRadioButton library and then hit finish.
5. You're done!

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following terminal command:

gem install cocoapods

To integrateLTHRadioButton into your Xcode project using CocoaPods, specify it in your Podfile:

source'https://github.com/CocoaPods/Specs.git'platform:ios,'9.0'use_frameworks!target'<Your Target Name>'dopod'LTHRadioButton'end

Then, run the following terminal command:

pod install

DragLTHRadioButton.swift from thesource folder into your Xcode project.

The initializer takes up to 3 params: adiameter, aselectedColor, and adeselectedColor. All of them are optional:

• diameter defaults to18
• selectedColor defaults to a light blue
• deselectedColor defaults toUIColor.lightGray

It doesn't use Auto Layout internally, but after initialization it will have a proper size, so you can simply create constraints based on itsframe.width andframe.height.

selectedColor anddeselectedColor have been made publicly customizable for cases like atableView with alternating row and radio colors, where thetableView might dequeue a cell with one color for displaying a cell with a different color.

isSelected - Indicates whether the radio button is selected.

useTapGestureRecognizer - Indicates whether a tap gesture recognizer should be added to the control when setting callbacks. This defaults totrue just so thatonSelect andonDeselect can add the gesture recognizer automatically, but the recognizer isnot added by default.

• Settings this totrue will also add the requiredUITapGestureRecognizer if needed.
• Settings this tofalse will also remove theUITapGestureRecognizer if it was previously added.

init(diameter:CGFloat=18, selectedColor:UIColor?=nil, deselectedColor:UIColor?=nil) // Colors default internally if nil.func select(animated:Bool=true) // Selects the radio button.func deselect(animated:Bool=true) // Deselects the radio button.

You can make use of theonSelect andonDeselect methods to add closures to be run when selecting/deselecting the control. Since these closures make most sense for taps and because there are no recognizers by default, these methods will also add one (and only one)UITapGestureRecognizer to the control to handle the taps; the closure calls happen right as the animations begin.

If you'd like to use the callbacks but don't need the tap gesture recognizer, you can setuseTapGestureRecognizer tofalse.

letradioButton=LTHRadioButton(selectedColor:.red)container.addSubview(radioButton)radioButton.translatesAutoresizingMaskIntoConstraints=falseNSLayoutConstraint.activate([  radioButton.centerYAnchor.constraint(equalTo: container.centerYAnchor),  radioButton.leadingAnchor.constraint(equalTo: container.leadingAnchor, constant:16),  radioButton.heightAnchor.constraint(equalToConstant: radioButton.frame.height),  radioButton.widthAnchor.constraint(equalToConstant: radioButton.frame.width)])radioButton.onSelect{print("I'm selected.")}radioButton.onDeselect{print("I'm deselected.")}[...]radioButton.select() // I'm selected.[...]radioButton.deselect(animated:false) // I'm deselected.

If you're using this control, I'd love hearing from you!
