CABasicAnimation* rotationAnimation = [CABasicAnimationanimationWithKeyPath:@"transform.rotation.z"];
rotationAnimation.toValue = [NSNumber numberWithFloat:(DEGREES_TO_RADIANS(angle))];
rotationAnimation.duration = 3;
rotationAnimation.autoreverses = YES; // Very convenient CA feature for an animation like this
[ballLayer addAnimation:rotationAnimation forKey:@"revItUpAnimation"];
transform.rotation.z 的意思是围绕着 Z轴做旋转（想象一下）
autoreverses = YES，当动画完了之后，回返回，YES表示慢慢返回，NO表示一下子返回。（当你设定这个属性为 YES 时,在它到达目的地之后,动画的返回到开始的值,代替了直接跳转到 开始的值。）
