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);
