UIImageView中播放动画

NSArray *gifList = @[ [UIImage imageNamed:@"speekBtn_1"], [UIImage imageNamed:@"speekBtn_2"],[UIImage imageNamed:@"speekBtn_3"]];
self.speekBtn.imageView.animationImages = gifList;
self.speekBtn.imageView.animationDuration = 1; //执行一次完整动画所需的时长
self.speekBtn.imageView.animationRepeatCount = 0;  //动画重复次数 0循环
[self.speekBtn.imageView startAnimating]; //开始动画

动画结束时：

[self.speekBtn.imageView stopAnimating];
self.speekBtn.imageView.animationImages = nil;
