Hard to help without seeing the code, but I guess you are calling stringByReplacingOccurrencesOfString:withString:, but not assigning the result back to a variable. Notice how this method returns a new object, but does not change the callee.

If you want to remove newlines, I suggest you use stringByTrimmingCharactersInSet::

key = [key stringByTrimmingCharactersInSet:[NSCharacterSet  newlineCharacterSet]];
