iOS - Dismiss keyboard when touching outside of UITextField

Question

I'm wondering how to make the keyboard disappear when the user touches outside of a UITextField.

Answer 1

You'll need to add an UITapGestureRecogniser and assign it to the view, and then call resign first responder on the UITextField on it's selector.

The code:

In viewDidLoad

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];

[self.view addGestureRecognizer:tap];

In dismissKeyboard:

-(void)dismissKeyboard 
{
    [aTextField resignFirstResponder];
}

(Where aTextField is the textfield that is responsible for the keyboard)

Swift 3 version looks like that

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard (_:)))
self.view.addGestureRecognizer(tapGesture)

For dismissKeyboard

@objc func dismissKeyboard (_ sender: UITapGestureRecognizer) {
    aTextField.resignFirstResponder()
}

Answer 2

I mashed up a few answers.

Use an ivar that gets initialized during viewDidLoad:

UIGestureRecognizer *tapper;

- (void)viewDidLoad
{
    [super viewDidLoad];
    tapper = [[UITapGestureRecognizer alloc]
                initWithTarget:self action:@selector(handleSingleTap:)];
    tapper.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tapper];
}

Dismiss what ever is currently editing:

- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
    [self.view endEditing:YES];
}

Answer 3

Check this, this would be the easiest way to do that,

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
      [self.view endEditing:YES];// this will do the trick
}

Or

This library will handle including scrollbar auto scrolling, tap space to hide the keyboard, etc...
