iOS App Development - How to Dismiss Keyboard

[MacDeuterium]

Hello everybody,

I need to know how to dismiss a keyboard when the user taps a UITextField either by:

1. The user tapping the 'Done' or the 'Return' button in the bottom left hand side of the keyboard, or;
2. The user tapping outside the keyboard field, and the keyboard is dismissed (preferred method)

I'm coding in Xcode 5 for iOS 7 so Objective - C is my preferred language, not Swift.

Thanks!

For question 2, you can try the below code:

- (void)touchesBeganNSSet *)touches withEventUIEvent *)event {

UITouch *touch = [[event allTouches] anyObject];
if ([_textField isFirstResponder] && [touch view] != _textField) {
[_textField resignFirstResponder];
}
[super touchesBegan:touches withEvent:event];
}

Change _textField by your name of textField.

This works really well!

Thanks a million

For the first question, it is somewhat more complicated (but still easy) to make the keyboard go away when the user taps the Done button. First, you have to conform your view controller to the UITextFieldDelegate. Then, you have to use the UITextField delegate method called textFieldShouldReturn:

#pragma mark UITextFieldDelegate methods
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [self.textField resignFirstResponder];
    return YES;
}

Inside of the viewDidLoad method of the view controller, make sure to set self.textFieldX.delegate = self.
