iOS view无限360度旋转和停止

- (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"];

}

如上代码，传入要旋转的view即可。

如果想要停止：

[self.playStatusImageView.layer removeAllAnimations];//停止动画
