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:(UITextField *)textField {
 if ( textField == userPassword ) {
  [textField resignFirstResponder];
 }
 return YES;
}

Normally the keyboard should be hidden but it stays on the screen. resignFirstResponder is correctly called. What am I missing?

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:

Modal Dialog Does Not Dismiss Keyboard

Modal View Controller with keyboard on landscape iPad changes location when dismissed

Answer 2

There is this helpful method which allows you to dismiss the keyboard when presenting the Modal Dialog:

 - (BOOL)disablesAutomaticKeyboardDismissal { return NO; }

This will override the default behavior of the modal dialog set by Apple and allow you dismiss the keyboard. It is in the UIViewController Class.

I hope this helps someone!

If you are using the Interface Builder, look if your UITextField has the delegated linked with your class.

-Select your UITextField and in your Connections look if exits one connection in Outlets->delegate. If not, conect with you File's Owner Class.

This need to be linked with your File's Owner Class. This delegate tell where to search for a method. If your are overriding a method, you need to tell where the object will search for that.

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];

Answer 5

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 6

I was having the same problem. I realized that after connecting the delegate to the File's Owner in Interface Builder, I neglected to save in Interface Builder. Once I saved, I recompiled and the keyboard disappears correctly when hitting return.

Answer 7

xcode 4.5.1

Simply click control then on the textfield drag and release on the .h file

(control key+ drag)

then in the pop up menu select

connection=acton;
name= any name;
type=id;
event=did end on exit;
arguments=sender;

then click connect button

Answer 8

Did you remember to implement the UITextFieldDelegate protocol?

Answer 9

I have read so many articles about this issue, where the onscreen keyboard refuses to hide when you call resignFirstResponder, but none of the suggestions worked for me.

I'm using XCode 5 (iOS 7) and have a iPhone screen containing a couple of controls which require the onscreen keyboard, but if the user clicks on the UIButton, then I want the keyboard to disappear.

I probably wasted one full day experimenting with resignFirstResponder and adding disablesAutomaticKeyboardDismissal functions to return NO, but nothing worked. Once the onscreen keyboard appeared, I could never get it to disappear again.

But then I had a small brainwave (as I only have a small brain).

Now, when the user clicks on my UIButton, I simply disable the UITextField and UITextView controls.

- (IBAction)btnDate_Tapped:(id)sender {
    //  The user has clicked on the "Date" button.
    self.tbClientName.enabled = NO;
    self.tbComments.editable = NO;

And suddenly, the app finds it has no editable text fields needing an onscreen keyboard, and it neatly slides the keyboard out of sight.

(Relieved sigh.)

My UIButton actually makes a popup dialog appear. When the user dismisses the popup, I re-enable these two controls, so if the user taps in one of them, the keyboard will appear again.

-(void)popoverControllerDidDismissPopover:(UIPopoverController *) popoverController {
    //  The user has closed our popup dialog.
    //  We need to make our UITextField and UITextView editable again.
    self.tbClientName.enabled = YES;
    self.tbComments.editable = YES;
    ... etc...
}

Simple, isn't it !

And surprisingly, this workaround even works on UIViewControllers which appear in Modal style.

I hope this helps other XCode victims out there.

Answer 10

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 11

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 12

if you are in UIModalPresentationFormSheet just call

- (BOOL)disablesAutomaticKeyboardDismissal
{
    return NO;
}

Answer 13

Swift 3.0:

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

Answer 14

Swift 3.0

func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {

    if textField == addressTextField {
        textField.resignFirstResponder()

        return false
    }

    return true
}
