Answer 1

The below code is for showing "DONE" button on NumberPad iOS 8 also. I run this code in XCode-5.1.1 with iOS 6/7/8 devices. Its working perfectly.

I take the refrence from this link Can't find keyplane that supports type 4 for keyboard iPhone-Portrait-NumberPad given some code for add button on Number keyboard.

@property (nonatomic, retain) UIButton *doneButton;

AddButton

- (void)addButtonToKeyboard
{
    if (!self.doneButton)
    {
        self.doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
        [self.doneButton addTarget:self action:@selector(doneButtonClicked:) 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];

    // locate keyboard view
    if ([[[UIApplication sharedApplication] windows] count] <= 1) return;
    UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
    UIView* keyboard;
    for(int i=0; i<[tempWindow.subviews count]; i++)
    {
        keyboard = [tempWindow.subviews objectAtIndex:i];
        // keyboard found, add the button
        if ([[keyboard description] hasPrefix:@"

removeButtonFromKeyboard

- (void)removeButtonFromKeyboard
{
    NSArray *arTemp = [[UIApplication sharedApplication] windows];
    if ([arTemp count] <= 1) return;
    UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
    UIView* keyboard;
    for(int i=0; i<[tempWindow.subviews count]; i++)
    {
        keyboard = [tempWindow.subviews objectAtIndex:i];
        // keyboard found, add the button
        if ([[keyboard description] hasPrefix:@"

Let me know any issues.

Update: Testing on iOS 7.1, real device - the button is not being added unless the keyboard show animation has finished. The code below adds a delay to add button once the keyboard is fully visible:

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    [self performSelector:@selector(addButtonToKeyboard) withObject:nil afterDelay:0.75];

}
