resignFirstResponder not hiding keyboard on textFieldShouldReturn

Question

I have a view with a UITextField which should hide the keyboard when return is pressed.

My function is this:

- (BOOL)textFieldShouldReturn:(UITextFie         


        

Answer 1

I see you have the iPad tag on this. Do you happen to be presenting a modal view using UIModalPresentationFormSheet? If so, it looks like this is a limitation of the FormSheet modal presentation (either Apple is doing it intentionally for some reason, or it is a bug). See these other questions for more details:

Answer 2

The easiest way is:

1. Go to your user interface builder,

2. select UITextField and "Control-Drag" to "Detail View Controller-Detail" and release.

3. The window will pop-up. Then under "Outlets" select "Delegate".

That's it. It worked for me.

Answer 3

To deal with the bug mentioned by Brandon, you can try closing and re-opening your modal view controller as long as you still have a reference to it.

[textField resignFirstResponder];
[self dismissModalViewControllerAnimated:NO];
[self presentModalViewController:yourModalViewControllerReference animated:NO];

(where "self" should be the controller you used to originally open the modal view controller)

Answer 4

Based on your comment that it looks like focus has shifted, then I think what may be happening is that the keyboard is staying open for the next text input field. If your return key is a "Next" key, then returning YES for textFieldShouldReturn: will make the next textField the first responder, and keep the keyboard visible.

Answer 5

This solution worked for me after none of the above did. after calling resignFirstResponder i added a modal view & removed it.

    [myTextField resignFirstResponder];
    UIViewController *dummyController = [[UIViewController alloc] init];
    UIView *dummy = [[UIView alloc] initWithFrame:CGRectMake(-1, -1,1,1)];
    [dummyController setView:dummy];
    [self presentModalViewController:dummyController animated:NO];
    [dummyController dismissModalViewControllerAnimated:NO];

Swift 3.0:

override var disablesAutomaticKeyboardDismissal: Bool {
    get{
        return false
    }
    set {
        self.disablesAutomaticKeyboardDismissal = false
    }
}
