一、为 UIView 添加点击事件

extension UIView { func addOnClickListener(target: AnyObject, action: Selector) { let gr = UITapGestureRecognizer(target: target, action: action) gr.numberOfTapsRequired = 1 userInteractionEnabled = true addGestureRecognizer(gr) } }

二、为 UIView 添加点击效果

class UIViewEffect : UIView { override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { backgroundColor = UIColor.groupTableViewBackgroundColor() } override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) { UIView.animateWithDuration(0.15, animations: { () -> Void in self.backgroundColor = UIColor.clearColor() }) } override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) { UIView.animateWithDuration(0.15, animations: { () -> Void in self.backgroundColor = UIColor.clearColor() }) } }
