是否可以创建一个自定义 UIButton 类,其中包含每次用户触摸按钮时都会自动调用的触摸事件动画?
Is it possible to create a custom UIButton class with an touch event animation which gets automatically invoked everytime the user touches the button?
import UIKit
class AnimatedButton: UIButton {
@objc private func buttonClicked(sender: UIButton) {
UIView.animate(withDuration: 0.5,
delay: 1.0,
usingSpringWithDamping: 1.0,
initialSpringVelocity: 0.2,
options: .curveEaseOut,
animations: {
//do animation
sender.transform = CGAffineTransform(scaleX: 0.6, y: 0.6)
},
completion: nil)
}
}
所以我不想在 ViewController 中创建必须调用 button.buttonTouched() 的操作.每次我在所有 UIButton 中使用此类时,都会自动发生这种情况.
So I don't want to create an action in a ViewController in which button.buttonTouched() must be invoked. This should happen automatically everytime I use this class in all UIButton.
有没有可能做这样的事情?
Is there any possibility to do something like that?
像这样创建按钮的自定义类
Create the button's custom class like this
class CustomButton:UIButton {
override init(frame: CGRect) {
super.init(frame: frame)
configeBtn()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
configeBtn()
}
func configeBtn() {
self.addTarget(self, action: #selector(btnClicked(_:)), for: .touchUpInside)
}
@objc func btnClicked (_ sender:UIButton) {
// animate here
}
}
