ios 图片简单360度旋转动画

只需要创建一个imgview，然后赋予图片和坐标
粘贴下面的代码就好啦。。。
旋转动画开启

- (void)rotateView:(UIImageView *)view
{
    CABasicAnimation *rotationAnimation;
    rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    rotationAnimation.toValue = [NSNumber numberWithFloat:M_PI*2.0];
    rotationAnimation.duration = 1;
    rotationAnimation.repeatCount = HUGE_VALF;
    [view.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
}

结束

[self.loadImgView.layer removeAllAnimations];
