LZ的代码,并不是按照Y找转,Y,Z同时都会动,按Y轴循环转动,有以下两种方法可供参考,推荐第一种方法,过渡更平滑,自然.

方法一:

CABasicAnimation* rotationAnimation;

rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];

rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 ];

rotationAnimation.duration = 3;

rotationAnimation.cumulative = YES;

rotationAnimation.repeatCount = MAXFLOAT;

[self.imageView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];

方法二:

[UIView animateWithDuration:3

delay:0

options:UIViewAnimationOptionRepeat

animations:^{

self.imageView.layer.transform=CATransform3DMakeRotation(M_PI, 0, 1, 0);

}

completion:^(BOOL finished) {

self.imageView.layer.transform=CATransform3DMakeRotation(M_PI, 0, 1, 0);

}];
