Hello Dimitri.
CAAnimation* rotateAnimation = [CABasicAnimation
animationWithKeyPath:@"transform"];
rotateAnimation.fromValue = [NSValue
valueWithCATransform3D:nLayer.transform];
rotateAnimation.toValue = [NSValue
valueWithCATransform3D:transform];
its gives me an error, Error request for member "fromValue" in
something not a structure or union.
shouldn't it be CABasicAnimation which has the fromValue and toValue
properties.?

rotateAnimation.duration = 0.4;
[rotateAnimation setValue:nLayer forKey:@"rotatedLayer"];
[rotateAnimation setDelegate:self];
[CATransaction begin];
[CATransaction setValue:(id)bCFBooleanTrue
forKey:kCATransactionDisableActions];
nLayer.transform = transform; // set the layers "actual" value
without the user noticing
[CATransaction commit];
[nLayer addAnimation:rotateAnimation
forKey:@"RotationAnimation"]; // set this so it replaces the
previous rotation if you click before 0.4 sec
}
}
Hope that works :3 (apologies if I forgot a semicolon or something,
i wrote it directly in mail)
