今天碰到个需要将图片一直旋转的需求，话不多说直接上代码

    CABasicAnimation *rotationAnimation;
    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];
    rotationAnimation.duration = 1;
    rotationAnimation.cumulative = YES;
    rotationAnimation.repeatCount = 10000;
    [_sendLoadingImageView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];

移除动画

[_sendLoadingImageView.layer removeAllAnimations];
