Using 3D transforms with iOS (iPad)

I'm getting a compile time error "Undefined symbols for architecture i386" when trying to use any 3D animation stuff like CATransform3DIdentity or CATransform3DMakeScale.

I'm using them like this:

imgV.layer.transform = CATransform3DMakeScale(512, 384, -100);

An开发者_如何学JAVAy ideas?

I just had the same problem this morning. I had to add the QuartzCore framework for this to work.
