I have an idea for a mobile application (initially targeting iPhone but would like to target others in the future) and am trying to decide the best way to package/sell the product.

Hi there, I've seen in the example code supplied by Apple references to how you should handle Core Data errors. I.e: NSError *error = nil; if (![context save:&error]) { /* Replace this implementation with code to handle the error appropriately. abort() causes the application to generate a crash log and terminate. You should not use ...
Ok, what I'm trying to achieve is to load an image as a single resource and then save different parts of it as a number of different textures (basically chopping the image into smaller squares and then saving them separately). For my game, simply mapping different sections of the original image to my shapes won't work and being able to ...

Hi guys, I followed an example from "Beginning iPhone 3 Development" which puts the code for the main view controller, a Tab Bar, in the delegate method. Is this the correct place to put this or should it be in a separate .h and .m file? All my subviews are in separate files so I'm wondering if I should have my tab bar view controller ...
