How do I dismiss the iOS keyboard?

Question

I have a UITextfield that i\'d like to dismiss the keyboard for. I can\'t seem to make the keyboard go away no matter what code i use.

Answer 1

1. Set up the "Did End On Exit" event in Xcode (right click on your text field).

2. Realize this method:

   -(IBAction) closeKeyboard:(id) sender {
       [_txtField resignFirstResponder];
   }
   

Answer 2

I've discovered a case where endEditing and resignFirstResponder fail. This has worked for me in those cases.

ObjC

[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];    
[self setEditing:NO];

Swift

UIApplication.shared.sendAction(#selector(resignFirstResponder), to: nil, from: nil, for: nil)

Answer 3

I suggest you add and action on your header file:

-(IBAction)removeKeyboard;

And in the implementation, write something like this:

-(IBAction)removeKeyboard
{
[self.textfield resignFirstResponder];
}

In the NIB file, connect from the UITextFiled to the File's Owner on the option DidEndOnExit. That way, when you press return, the keyboard will disappear.

Hope it helps!

Answer 4

This will resign one particular text field

// Swift
TextField.resignFirstResponder()

// Objective C
[TextField resignFirstResponder];

To resign any text field use below code

// Swift
self.view!.endEditing(true)

// Objective C
[self.view endEditing:YES];

Answer 5

If you don't know which textField is the first responder you can find it. I use this function:

UIView *resignFirstResponder(UIView *theView)
{
    if([theView isFirstResponder])
    {
        [theView resignFirstResponder];
        return theView;
    }
    for(UIView *subview in theView.subviews)
    {
        UIView *result = resignFirstResponder(subview);
        if(result) return result;
    }
    return nil;
}

Then in your code call:

    UIView *resigned = resignFirstResponder([UIScreen mainScreen]);

3 Simple & Swift steps

Add UITextFieldDelegate to your class as below:

class RegisterVC: UIViewController, UITextFieldDelegate {
    //class implementation 
}

in class implementation, add the delegate function textFieldShouldEndEditing::

internal func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    self.view.endEditing(true)
    return true
}

and as a last step, set your UITextField(s) delegate(s) to self, in somewhere appropriate. For example, inside the viewDidLoad function:

override func viewDidLoad(){
    super.viewDidLoad()
    myTextField1.delegate = self
    myTextField2.delegate = self
    ..
    ..
}

Now, whenever user hits the return key, keyboard will dismiss.

I prepared an example snippet too, you can check it from here.
