Swift开发教程--怎样播放图片动画

废话少说，直接上代码：

var barsAnim = UIImageView(frame: self.view.frame);

barsAnim.animationImages =
NSArray() as [AnyObject];

barsAnim.animationImages?.append(UIImage(named:
"wave_000")!);

barsAnim.animationImages?.append(UIImage(named:
"wave_001")!);

barsAnim.animationImages?.append(UIImage(named:
"wave_002")!);

barsAnim.animationImages?.append(UIImage(named:
"wave_003")!);

barsAnim.animationImages?.append(UIImage(named:
"wave_004")!);

barsAnim.animationImages?.append(UIImage(named:
"wave_005")!);

barsAnim.animationDuration = 2;

barsAnim.animationRepeatCount =
0;

barsAnim.startAnimating();

self.view.addSubview(barsAnim);
