1.先初始化一个UIImageView的视图窗口 如：anima     UIImageView *anima = [UIImageView alloc]initWithFrame(0,0,100,100);2.animationImage 设置一个 UIImageView播放的动态数组      anima.animationImage = imageList()；3. animationDuration 设置一组动画需要的时间      anima.animationDuration = 1;(为-1时是一直播放) 4.animationRepeatCount 设置需要播放的次数      anima.animationRepeatCount = 4;5.startAnimating 让动画开始     [anima startAnimating];6.stopAnimating 让动画停止      [anima stopAnimating];7.isAnimating 判断动画是否正在播放      anima.isAnimating = YES;
