Objective-C determine what objects retain another object?

The leaks tool (one of the "instruments" in XCode) is able to analyse that sort of thing, but I don't think you can do it programatically.

Try using the Build & Analyze. It can usually tell you if an object is being retained and not released.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
