UIImageView简单动画处理

1、使用imageview实现GIF小动画

    //创建一个数组，数组中按顺序添加要播放的图片（图片为静态的图片）
    NSMutableArray *imgArray = [NSMutableArray array];
    for (int i=0; i<35; i++) {
        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"donghua_%02d",i]];
        [imgArray addObject:image];
    }
    //把存有UIImage的数组赋给动画图片数组
    _animationImgView.animationImages = imgArray;
    //设置执行一次完整动画的时长
    _animationImgView.animationDuration = 35*0.06;
    //动画重复次数 （0为重复播放）
    _animationImgView.animationRepeatCount = 1;
    //开始播放动画
    [_animationImgView startAnimating];

2、imageview一定角度旋转动画

        self.static_lightImgView.image = [UIImage imageNamed:@"guang"];
        CABasicAnimation* rotationAnimation;
        rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
        rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 1.0];
        rotationAnimation.duration = 6;
        rotationAnimation.cumulative = YES;
        rotationAnimation.repeatCount = 1;
        
        [self.static_lightImgView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
