【问题描述】：

我有对角向下动画的代码。

CABasicAnimation *rightAnimation = [CABasicAnimation animationWithKeyPath:@"transform.translation.x"];
[rightAnimation setToValue:[NSNumber numberWithFloat:160]];
[rightAnimation setBeginTime:0.0];
[rightAnimation setDuration:0.4];


CABasicAnimation *fall = [CABasicAnimation animationWithKeyPath:@"transform.translation.y"];
[fall setToValue:[NSNumber numberWithFloat:-20]];
[fall setBeginTime:0.1];
[fall setDuration:0.3];

//DOESN'T WORK
CABasicAnimation *rotate = [CABasicAnimation animationWithKeyPath:@"transform.translation.z"];
[rotate setToValue:[NSNumber numberWithFloat:DEGREES_RADIANS(30)]];
[rotate setBeginTime:0.0];
[rotate setDuration:0.4];

CAAnimationGroup *group = [CAAnimationGroup animation];
[group setDuration:0.4];
[group setAnimations:[NSArray arrayWithObjects:rightAnimation, fall, rotate, nil]];

[submitButton.layer addAnimation:rotate forKey:nil];

除了我还想让按钮旋转 30 度之外，它可以完美地工作。但是由于某种奇怪的原因，这并没有发生，怎么会呢？

【参考方案1】：

改变这一行：

CABasicAnimation *rotate = [CABasicAnimation animationWithKeyPath:@"transform.translation.z"];

到这里：

CABasicAnimation *rotate = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];

这应该可以解决您的问题。

【参考方案2】：

我从未见过“DEGREES_RADIANS”，我相信您实际上可能指的是“degreesToRadians”。如果是这样，下面的代码就足够了：

rotationAnimation.toValue = [NSNumber numberWithFloat:degreesToRadians(30)];
