Answer 1

First of all we are declaring new variable:

@property (strong, nonatomic) UIButton *doneButton;

Call button initialization in viewDidLoad:

- (void)setupDoneButton {
    if (!self.doneButton) {
        self.doneButton = [UIButton buttonWithType:UIButtonTypeSystem];
        [self.doneButton addTarget:self action:@selector(tapGestureRecognizerAction) forControlEvents:UIControlEventTouchUpInside];
        self.doneButton.adjustsImageWhenHighlighted = NO;
        [self.doneButton setTitle:@"DONE" forState:UIControlStateNormal];
        [self.doneButton.titleLabel setFont:[UIFont systemFontOfSize:16.0]];
        [self.doneButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [self.doneButton setTitleColor:[UIColor blackColor] forState:UIControlStateHighlighted];
    }
}

Show button in keyboardDidShow or textFieldDidBeginEditingmethod:

- (void)addDoneButtonToKeyboard {
    dispatch_async(dispatch_get_main_queue(), ^{
    UIWindow *keyboardWindow = [[[UIApplication sharedApplication] windows] lastObject];
    CGFloat buttonWidth = CGRectGetWidth(keyboardWindow.frame)/3;
    self.doneButton.frame = CGRectMake(0.f, CGRectGetHeight(keyboardWindow.frame) - 53, buttonWidth, 53);
    [keyboardWindow addSubview:self.doneButton];
    [keyboardWindow bringSubviewToFront:self.doneButton];
    });
}

Than remove button in keyboardWillHide or textFieldDidEndEditing method:

    [self.doneButton removeFromSuperview];

This works on both iOS8 and iOS9.
