ImageView组图实现帧动画

UIImageView * gifImageView = [[UIImageViewalloc] initWithFrame:CGRectMake(100,100, 100,100)];
//添加图片
gifImageView.animationImages = [NSArrayarrayWithObjects:
[UIImageimageNamed:@"图片1"],
[UIImageimageNamed:@"图片2"],
[UIImageimageNamed:@"图片3"],
[UIImageimageNamed:@"图片4"],
nil];
gifImageView.animationDuration =1.0; //执行一次完整动画所需的时长
gifImageView.animationRepeatCount =0;  //动画重复次数 0为无限次播放
[gifImageView startAnimating];  // 开始动画
[gifImageView stopAnimating];   //停止动画››
[self.viewaddSubview:gifImageView];
