dismiss keyboard when touching outside of textfield

You'll need to add an UITapGestureRecogniser and assign it to the view, and then call resign first responder on the textfield 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)
