UIImageView *animationView = [[UIImageView alloc]initWithFrame:CGRectMake(40, 22.5, 15, 15)];
    //未开始的图片
    animationView.image = [UIImage imageNamed:@"icon_animation_01"];
    //动画效果图片（按照播放顺序放置）
    animationView.animationImages = [NSArray arrayWithObjects:
                                     [UIImage imageNamed:@"icon_animation_01"],
                                     [UIImage imageNamed:@"icon_animation_02"],
                                     [UIImage imageNamed:@"icon_animation_03"],nil];
    //设置动画间隔
    animationView.animationDuration = 1;
    animationView.animationRepeatCount = 0;
    animationView.userInteractionEnabled = NO;
    animationView.backgroundColor = [UIColor clearColor];
    
    [self.view addSubview:animationView];
    
    //开始动画
    [animationView startAnimating];
    //结束动画
    [animationView stopAnimating];
