Hi David, thank you for your response;
I've also tried to use:
[CATransaction begin];
[CATransaction setAnimationDuration:4.0];
hostViewLayer.affineTransform =
CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(-90));
[CATransaction commit];
and using:
hostViewLayer.transform =
CATransform3DMakeRotation(DEGREES_TO_RADIANS(-90),0,0,1);
(while animation is not played) coordinates still at the old position
(portrait) of the layer.
What am I wong?
