I just opened an iPad app I'd been working on and it was working fine, until now. I open it and the screen remains black, even after it's loaded! It's an OpenGL and I just downloaded the iOS4 SDK. I also added a provisioning profile. Would any of these changes result in a completely black screen with no error for no reason at all?
It loads the MainWindow.xib but doesn't show it. It's thinking but doesn't register touch events. All this was working until now.
