Add or hide Keyboard bottons in iOS

In a project I’m developing, I need to hide the language button of the keyboard. To do this I thought of adding a new button with the same background color as  the keyboard background color.

If you have this problem use this code to fix it.

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField

{

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];

…

}

-(void) keyboardDidShow:(NSNotification *)aNotification

{

     [self hideLanguageButtonInKeyboard:valueTextField];

}

- (void)hideLanguageButtonInKeyboard:(UITextField *)textField

{

UIButton *doneButton = [UIButton buttonWithType:UIButtonTypeCustom];

doneButton.frame = CGRectMake(38, 173, 43, 41);

doneButton.adjustsImageWhenHighlighted = YES;

[doneButton setImage:[UIImage imageNamed:@"hide_language_button.png"] forState:UIControlStateNormal];

[doneButton setImage:[UIImage imageNamed:@"hide_language_button.png"] forState:UIControlStateHighlighted];

//[doneButton addTarget:self action:@selector(resignKeyboard) forControlEvents:UIControlEventTouchUpInside];

if ([[[UIApplication sharedApplication] windows] count] > 1) {

UIWindow* tempWindow = [[[UIApplication sharedApplication] windows] objectAtIndex:1];

UIView* keyboard;

for(int i=0; i<[tempWindow.subviews count]; i++) {

keyboard = [tempWindow.subviews objectAtIndex:i];

if([[keyboard description] hasPrefix:@”

{

if(textField.keyboardType == UIKeyboardTypeDefault)

[keyboard addSubview:doneButton];

}

}

}

}
