Hi, I just realised that my 'root' viewController should have been a UINavigationController. Now I want to change this to be a UINavigationController instead and just curious what my best option would be. I built this view and all other views using IB if that makes a different. I'm mostly worried that I would have to do a lot of copy/p...

I made a little clock-like app which should play and loop a sound at a given moment (lets say 18:00). But when I press the power button, and the phone locks, nothing happens at 18:00. When I press the power button again 18:05 and ...

I understand that an upgrade to the iPhone OS upgraded the OpenGL ES version support from 1.1 to 2.0. What I haven't been able to find is whether effort should be made to use 1.1 for backwards compatibility with older devices. Xcode seems to suggest I using 2.0, since it only seems to include that version. Should I use 2.0 and not loo...

I'm not sure if there's a name for this, but essentially what I need to do is take two opaque sprites, draw them both at 50% opacity, and where they overlap, don't have it look darker.
