导读：class ViewController: UIViewController { @IBOutlet weak var layerView: UIView! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view,typically from a nib. // CATransition 是CAAnimation的子类用

class ViewController: UIViewController {

@IBOutlet weak var layerView: UIView!

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view,typically from a nib.

// CATransition 是CAAnimation的子类用于做转场动画，能够为层提供移出和移入屏幕的方法

}

override func touchesBegan(_ touches: Set<UITouch>,with event: UIEvent?) {

let transition:CATransition = CATransition()

transition.type = kCATransitionPush

transition.subtype = kCATransitionFromBottom

transition.duration = 8

transition.isRemovedOnCompletion = true

let layerViewLayer = self.layerView.layer

layerViewLayer.add(transition,forKey: "")

}

override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}

}
