question about done button

[rogomantik]

Hi, Why did you used

    [self setDoneButton:[[UIBarButtonItem alloc] initWithTitle:NSLocalizedStringFromTable(@"Done", @"BSKeyboardControls", @"Done button title.")
                                                         style:UIBarButtonItemStyleDone
                                                        target:self
                                                        action:@selector(doneButtonPressed:)]];

instead of

[self setDoneButton:[[UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemDone target:self action:@selector(doneButtonPressed:)]];
