对UIButton进行子类化并覆盖触摸事件 - 无法正常工作

Question

我需要一个项目中所有按钮的缩放弹簧动画.所以我将UIButton子类化并覆盖触摸事件函数.

import UIKit

class UIAnimatedButton: UIButton {

override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {

    UIView.animateWithDuration(0.1, animations: { () -> Void in
        self.transform = CGAffineTransformMakeScale(0.8, 0.8)

    })
    super.touchesBegan(touches, withEvent: event)

}

override func touchesCancelled(touches: Set<NSObject>!, withEvent event: UIEvent!) {


    UIView.animateWithDuration(0.5,
        delay: 0,
        usingSpringWithDamping: 0.2,
        initialSpringVelocity: 6.0,
        options: UIViewAnimationOptions.AllowUserInteraction,
        animations: { () -> Void in
            self.transform = CGAffineTransformIdentity
    }) { (Bool) -> Void in
        super.touchesCancelled(touches, withEvent: event)
    }

}


override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {

    UIView.animateWithDuration(0.5,
        delay: 0,
        usingSpringWithDamping: 0.2,
        initialSpringVelocity: 6.0,
        options: UIViewAnimationOptions.AllowUserInteraction,
        animations: { () -> Void in
            self.transform = CGAffineTransformIdentity
        }) { (Bool) -> Void in
            super.touchesEnded(touches, withEvent: event)
    }
  }
} 

这在快速敲击时效果很好但是当我长按(1-2秒)按钮时,我没有在动作事件中进行修饰.当我将它切换回常规UIButton时,一切正常.

任何想法为什么会发生？

而不是在我在那里调用的完成块touchesCancelled和touchesEnded方法中调用super self.sendActionsForControlEvents(UIControlEvents.TouchUpInside).
