I'm creating an openGL game and so far I have been using .pngs in the RGBA8888 format as texture sheets, but those are too memory hungry, and my app crashes frequently.

I have a requirement to create some NSDecimalNumber objects objects as part of my application (as I require the precision of calculation they offer) but I note that in calculations they return NSDecimalNumber objects which are, presumably, autoreleased.

My application's root view controller is a UITabBarController, where each tab is a UINavigationController. Everything works great. Now I've come to a place where I want to edit the stack, so I re...
