This works in the simulator like a charm. However, on the iPhone there's a really annoying flickering during the transition. I have no idea what is causing it.
If I transition (using kCATransitionFade) from the old view to the new view, it works ok, but if I do it like I described above, the annoying flickering happens. The only difference between these two situations is that in the latter case I'm launching a new transition from the animationDidStop method (while in the former case I'm not). I have no idea if this is what is causing the problem (or why it would be).

I've got exactly this same "flickering" problem, same symptoms. But I'm using only one CATransition. It happens randomly. Actually, I'm using several transitions but on different layers (sometimes with a parent relationship), so I don't think this will be the source of trouble. It would be nice to find some good explanation about the way calayer animate catransition, what (and when) it does things, in the "render tree" or anywhere else...
