CABasicAnimation基于二个方向的旋转

1     CABasicAnimation *transformAnimation = [CABasicAnimation animationWithKeyPath:@"transform"];
2     transformAnimation.fromValue = [NSValue valueWithCATransform3D:CATransform3DIdentity];
3     transformAnimation.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(DEGREES_TO_RADIANS(85), 0, 1, 1)]; //  基于Y轴和Z轴同时旋转
4     transformAnimation.duration = 1.5;
5     transformAnimation.autoreverses = YES;
6     transformAnimation.repeatCount = HUGE_VALF;
7     transformAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

 

 1     int tx = 0;

 3         [layer addAnimation:transformAnimation forKey:nil];  // 每个子层都加入Y轴和Z轴旋转
