I'm trying to animate a CATransformLayer (the transform layer is a sublayer of
the layer of a layer hosting NSView). Here's my animation code:
CGFloat zDistance = 850;
CGFloat scaleFactor = BACK_COVER_WIDTH /
self.transformLayer.bounds.size.width;
CATransform3D rotation = CATransform3DMakeRotation(M_PI, 0.0, 1.0, 0.0);
CATransform3D scale = CATransform3DMakeScale(scaleFactor, scaleFactor, 0.0);
CATransform3D transform = CATransform3DConcat(rotation, scale);
transform.m34 = 1.0 / -zDistance;
CGPoint location = CGPointMake(CGRectGetMidX(self.layer.frame),
CGRectGetMidY(self.layer.frame));
[CATransaction begin];
[CATransaction setAnimationDuration:1.0];
self.transformLayer.transform = transform;
self.transformLayer.position = location;
[CATransaction commit];
self.transformLayer is a CATransformLayer with two sublayers, one for the front
and one for the back (I'm creating a "flip" effect). However, this code just
sets the position and transform without animation. So I thought that maybe
transform doesn't support implicit animation, so I took that out and just tried
setting the position, but that didn't animate either (and I know for sure that
position supports implicit animation).
Am I doing something wrong or does CATransformLayer just not support implicit
animation? The documentation does not say anything about it not supporting it,
so I'm assuming it does._______________________________________________
