Question

在这里，我在视图控制器类上放置了两个单选按钮，但无法给出逻辑，一次激活一个单选按钮，任何人都可以帮助我吗？

@IBAction func radioButtonAction(_ sender: KGRadioButton) {
    sender.isSelected = !sender.isSelected

    if sender.isSelected {
        workRadioButton.isSelected = false
    } else{

    }

}
@IBAction func WorkRadiobuttonAction(_ sender: KGRadioButton) {

    sender.isSelected = !sender.isSelected

    if sender.isSelected {
        homeRadioButton.isSelected = false
    } else{

    }
}

我只是将UIButton用作radioButton.try，如下所示

创建一个数组来存储单选按钮

var radioButtonArray = [UIButton]()

将您的单选按钮声明为UIButton或anyOther

@IBOutlet weak var radioButton1: UIButton!
@IBOutlet weak var radioButton2: UIButton!

将所有按钮附加到数组

 radioButtonArray.append(contentsOf: [radio1,radio2])

为所有按钮设置相同的目标

self.radioButton1.addTarget(self, action: #selector(self.folderRadioButtonClicked(_:)), for: UIControlEvents.touchUpInside)
self.radioButton2.addTarget(self, action: #selector(self.folderRadioButtonClicked(_:)), for: UIControlEvents.touchUpInside)

func folderRadioButtonClicked(_ sender:UIButton) {
    for i in 0..<self.radioButtonArray.count {
        if self.radioButtonArray[i] == sender{
            // here you can perform what you want
            self.radioButtonArray[i].setImage(UIImage(named: "checked.png"), for: UIControlState())
        }else {
            self.radioButtonArray[i].setImage(UIImage(named: "unchecked.png"), for: UIControlState())
        }
    }
}

如何对两个单选按钮进行操作以一次激活一个？
