        UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];
        doneButton.frame = CGRectMake(0, 163, 106, 53);
        doneButton.adjustsImageWhenHighlighted = NO;

            else if([[keyboard description] hasPrefix:@"<UIInputSetContainerView"] == YES){
                for(int j = 0 ; j < [keyboard.subviews count] ; j++) {
                    UIView* hostkeyboard = [keyboard.subviews objectAtIndex:j];
