视图的大小应该是随时可控的。今天我们就来实现对一个View的缩放动画。该动画的实现与位移动画,透明度动画稍有不同。
详细实现例如以下:
import UIKit class ScaleViewController: UIViewController { @IBOutlet weak var greenSquare: UIView! override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view. } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } override func viewDidAppear(animated: Bool) { super.viewDidAppear(animated) func anim(){ self.greenSquare.transform = CGAffineTransformMakeScale(0.5, 0.5)//缩小为原来的0.5倍。 } UIView.animateWithDuration(1, animations: anim) } }
(3)执行程序。发现View能够变为原来X。Y轴上的0.5倍。
