I’ve been trying to figure this out for a while but I can’t seem to get it. How would I swap two NSViews using a push transition (like what UINavigationController does on iOS)? What I’ve tried so far:

  • Using an NSAnimation subclass <– too slow
  • Using NSViewAnimation and MGViewAnimation <– too slow
  • Using the NSView animator proxy <– too slow
  • Using CATransition <– I can’t use this because CATransition requires the views to be layer backed, and layer backing views causes text rendering glitches as well as various other graphical artifacts

    It seems that the animation is slow because I’m animating a pretty large view. I don’t think there’s any way around that other than the good old image swap trick (taking an image of the view and animating that instead of the view itself).
