    The objects returned from -objectAtIndex: are technically both.

    The code looks something like this:

     -(id) objectAtIndex:(NSUInteger) index
 { 
      return [[objects_[index] retain] autorelease];
 }

    So they don’t belong to you, but if you remove it from the array, it won’t be immediately deallocated.
