I'm currently working on moving some Android-ndk code to the iPhone.
From looking at some samples it seems that the main loop is handled for you and all you've got to do is override the render method on the view to handle the rendering. Then add a selector to handle the update methods. The render method itself looks like it's attached to the windows refresh.
But in android I've got my own game loop that controls the rendering and updates using C++
time.h. Is it possible to implement the same here bypassing Apple's loop? I'd really like the keep the structures of the code similar.
