What are the best practices for exceptions/returning NO/nil in Objective-c?

I won't be definitive about which to use, but here's some info about each of the options.

Exceptions should be used as little as possible in Objective-C. Where other languages would use exceptions, in Objective-C it's recommended to make use of NSError objects most of the time.

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.
