IOS 8.3 Number Pad custom OK button - ios

Question

I am developing an IOS application. I am using custom Ok button for iPhone number pad. This code work in all IOS version but IOS 8.3 not working.OK button added to keyboard but click event not working.
- (void)updateKeyboardButtonFor:(UITextField *)textField {
// Remove any previous button
[self.numberPadDoneButton removeFromSuperview];
self.numberPadDoneButton = nil;
// Does the text field use a number pad?
if (textField==nil || textField.keyboardType != UIKeyboardTypeNumberPad){
return;
}
// If there's no keyboard yet, don't do anything
if ([[[UIApplication sharedApplication] windows] count] < 2)
return;
UIWindow *keyboardWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
// Create new custom button
self.numberPadDoneButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.numberPadDoneButton.frame = CGRectMake(0, 163, 106, 53);
self.numberPadDoneButton.adjustsImageWhenHighlighted = FALSE;
[self.numberPadDoneButton setImage:self.numberPadDoneImageNormal forState:UIControlStateNormal];
[self.numberPadDoneButton setImage:self.numberPadDoneImageHighlighted forState:UIControlStateHighlighted];
[self.numberPadDoneButton addTarget:self action:#selector(numberPadDoneButton:) forControlEvents:UIControlEventTouchUpInside];
/*
// Locate keyboard view and add button
NSString *keyboardPrefix = [[[UIDevice currentDevice] systemVersion] floatValue] >= 3.2 ? #"<UIPeripheralHost" : #"<UIKeyboard";
for (UIView *subView in keyboardWindow.subviews) {
if ([[subView description] hasPrefix:keyboardPrefix]) {
[subView addSubview:self.numberPadDoneButton];
[self.numberPadDoneButton addTarget:self action:#selector(numberPadDoneButton:) forControlEvents:UIControlEventTouchUpInside];
break;
}
}
*/
UIWindow* tempWindow;
UIView* keyboard;
for (UIWindow *window in [[UIApplication sharedApplication] windows])
{
if ([NSStringFromClass([window class]) isEqualToString:#"UITextEffectsWindow"])
{
tempWindow = window;
break;
}
}
for(int i = 0 ; i < [tempWindow.subviews count] ; i++)
{
keyboard = [tempWindow.subviews objectAtIndex:i];
// keyboard found, add the button
if([[keyboard description] hasPrefix:#"<UIPeripheralHost"] == YES){
[keyboard addSubview:self.numberPadDoneButton];
}
//This code will work on iOS 8.0
else if([[keyboard description] hasPrefix:#"<UIInputSetContainerView"] == YES){
for(int i = 0 ; i < [keyboard.subviews count] ; i++)
{
UIView* hostkeyboard = [keyboard.subviews objectAtIndex:i];
if([[hostkeyboard description] hasPrefix:#"<UIInputSetHost"] == YES){
[hostkeyboard addSubview:self.numberPadDoneButton];
BOOL isPortrait = UIInterfaceOrientationIsPortrait([UIApplication sharedApplication].statusBarOrientation);
self.numberPadDoneButton.frame = CGRectMake(((isPortrait) ? 0 : -1),((int) (hostkeyboard.frame.size.height*3)/4) + ((isPortrait) ? 0 : 1),(int) hostkeyboard.frame.size.width/3-1, (isPortrait) ? 60 : 40);
[self.numberPadDoneButton addTarget:self action:#selector(numberPadDoneButton:) forControlEvents:UIControlEventTouchUpInside];
}
}
}
}
}
