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

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 2

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 3

Did you remember to implement the UITextFieldDelegate protocol?

Answer 4

if you are in UIModalPresentationFormSheet just call

- (BOOL)disablesAutomaticKeyboardDismissal
{
    return NO;
}

Answer 5

Swift 3.0

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

    if textField == addressTextField {
        textField.resignFirstResponder()

        return false
    }

    return true
}

Answer 6

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!
