I wonder if I've been doing too much myself, and could be relying on CoreData more. Suppose I have two managed objects, Dog and Tail, which have a one-to-one relationship. Dog has a relationship, tail, that is optional. Its inverse is owningDog. The delete rule from Dog to Tail is cascade. Tail's owningDog relationship is also optional. ...

I am looking for anyone that can help create some source and a tutorial with me to answer how to create a game like "air control" or "harbor patrol" - just a simple source file where a user can draw using their finger and an object will follow - no need for final collision detection just the simple follow path source.

I'm working on a game and I'd like to give a non-developer friend a little level editor so they can build levels while I continue working on the development. I quickly knocked up the following to see if it would create a file my friend could copy and email to me for later use. // Archive Test NSMutableDictionary *leveldata = [NS...

I don't have a mac, but I will be doing mo...
For a basic app with nonconsumable in-app purchases, has anyone figured out best practices for using SKPaymentQueue's restoreCompletedTransactions? Observations I know it's recommended to always register a transaction observer to receive pending transactions that make their way back to the app, but this is a different question. It loo...

I'm completely new to OpenGL, and I'm trying draw on a white background by reverse engineering GLPaint. I've gone through every combination of kSaturation, kLuminosity and glBlendFunc, AND just about every combination I can think of for brush texture (black on white, white on black, white on trans, alias/no alias, etc), but haven't stumb...
