UIKeyboardTypeNumberPad without a done button

Question

How can we implement UIKeyboardTypeNumberPad so that it will have a \'done\' button? By default it does not have one.

Answer 1

If anybody had a problem that the DONE button keeps popping up when you try to load other types of keyboards in the same app, I know a lot of apps out there have this issue. Anyway, here is how I solved this: In your ViewController ( the same viewcontroller that you added DONE button ) add this code ( as is ) and it should solve your problems with DONE button keep reappearing. Hope it helps to some folks.

- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2) {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidShowNotification object:nil];   
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardDidHideNotification object:nil];

} else {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];  
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

}
