When removed from array object gets released once. So if your retain/release are paired correctly in other places you must not release your object in this case.

If the NSArray (um, it is an NSArray, isn't it? C arrays provide no ownership management) is the only thing that owns the object -- that is, if the object added was acquired autorelease-d or you explicitly called release after adding -- then it will be cleaned up automatically on removal. Any other ownership claims will still need to be release-d as normal.

In fact, your talking about NSMutableArray
And it does the release 'automatically'. So do
[array add: @"SAFEY-STRING" ];
and don't do
[array add: [[NSString alloc] initWithFormat:@"LEAKY-STRING"] ];
