iOS CAKeyFrameAnimation 회전

Question

나는이 CAKEyFrameAnimaton을 작성하여 CALayer을 X 축에 회전 시켰습니다. 그러나 그것은 회전하지 않습니다. 여기서 내가 뭘 잘못하고 있니?

CAKeyframeAnimation *topFoldAnimation = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation.x"]; 
topFoldAnimation.duration    = 15; 
topFoldAnimation.repeatCount   = 1; 
topFoldAnimation.removedOnCompletion = NO; 
topFoldAnimation.autoreverses   = NO; 
topFoldAnimation.fillMode    = kCAFillModeForwards; 

CATransform3D tTrans     = CATransform3DIdentity; 
tTrans.m34       = -1/900; 

topFoldAnimation.values    = [NSArray arrayWithObjects: 
             [NSValue valueWithCATransform3D:CATransform3DRotate(tTrans,DEGREES_TO_RADIANS(0),1,0,0)], 
             [NSValue valueWithCATransform3D:CATransform3DRotate(tTrans,DEGREES_TO_RADIANS(-30),1,0,0)], 
             [NSValue valueWithCATransform3D:CATransform3DRotate(tTrans,DEGREES_TO_RADIANS(-60),1,0,0)], 
             [NSValue valueWithCATransform3D:CATransform3DRotate(tTrans,DEGREES_TO_RADIANS(-90),1,0,0)], 
              nil]; 
topFoldAnimation.keyTimes    = [NSArray arrayWithObjects: 
              [NSNumber numberWithFloat:0.00], 
              [NSNumber numberWithFloat:0.25], 
              [NSNumber numberWithFloat:0.50], 
              [NSNumber numberWithFloat:1.00], 
              nil]; 
topFoldAnimation.timingFunctions  = [NSArray arrayWithObjects: 
             [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear], 
             [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear], 
             [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear], 
             [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear], 
              nil]; 
[[backgroundAnimationLayer.sublayers objectAtIndex:1] addAnimation:topFoldAnimation forKey:@"transform.rotation.x"]; 

도움을 주시면 감사하겠습니다. 감사합니다 ...

당신의 애니메이션 keyPath가 잘못되었습니다, 그것은 transform이 아니고 transform.rotation.x이 아니어야합니다.

또한 정수 배분을 사용하고 있기 때문에 0은 tTrans.m34으로 끝납니다. 아마 -1.0/900이어야합니다.
