How to add Done button to the keyboard?

Question

thats quite simple 🙂

[textField setReturnKeyType:UIReturnKeyDone];

for dismissing the keyboard implement the <UITextFieldDelegate> protocol in your class, set

textfield.delegate = self;

and use

- (void)textFieldDidEndEditing:(UITextField *)textField {
    [textField resignFirstResponder];
}

or

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return YES;
}
