Writing an app that will include the ability to decompress zip and rar files. I think I'm OK on how to handle the .zips but .rars seem a little more trouble.

Say I have: @property (nonatomic,retain) NSString *foo; in some class.

Or the fact that nothing is pointing to th...

Thanks! ...
I know the title of this question is a bit confusing, but here it goes anyway: I'm creating an NSString after an if statement but it just doesn't seem to want to retain outside of the statement.
