Group RadioButton

###Sample Code Sample code would look like this

class ViewController: UIViewController, RadioGroupDelegate {
    
    @IBOutlet private weak var firstButton: RadioButton!
    @IBOutlet private weak var secondButton: RadioButton!
    @IBOutlet private weak var thirdButton: RadioButton!
    
    private var groupController: RadioGroupController?

    override func viewDidLoad() {
        super.viewDidLoad()
        
        groupController = RadioGroupController(buttons: [firstButton, secondButton, thirdButton])
        groupController?.delegate = self
        
    }

    func didSelectedButton(_ index: Int?, value: String?) {
        print("Index => \(index), selected value => \(value)")
    }

}

Programmatically

class ViewController: UIViewController, RadioGroupDelegate {
    
    @IBOutlet private weak var firstButton: RadioButton!
    @IBOutlet private weak var secondButton: RadioButton!
    @IBOutlet private weak var thirdButton: RadioButton!
    
    private var groupController: RadioGroupController?

    override func viewDidLoad() {
        super.viewDidLoad()
        
        groupController = RadioGroupController()
        
        // Step 1 with group id
        groupController.addButtons([firstButton, secondButton, thirdButton], groupId: "") 
        groupController?.delegate = self
        
        // Step 2 with group id and multiselection
        
        groupController.addButtons([firstButton, secondButton, thirdButton], groupId: "", isMultiSelectionEnabled: Bool) 
        groupController?.delegate = self
        
    }

    func didSelectedButton(_ index: Int?, value: String?) {
        print("Index => \(index), selected value => \(value)")
    }

}

Demo

Get currently selected button

To get the currently selected button, you can use

var currentButton = groupController.selectedButton

To get the currently selected button index, you can use

var selectedIndex = groupController.selectedIndex

To get the currently selected button value, you can use

var selectedValue = groupController.selectedValue

To get the currently selected group id, you can use

🎨 Customization

    firstButton.defaultColor = UIColor.black
