How to hide the keyboard when I press return key in a UITextField?

Question

Clicking in a textfield makes the keyboard appear. How do I hide it when the user presses the return key?

Solution 1

First make your file delegate for UITextField

@interface MYLoginViewController () <UITextFieldDelegate>

@end

Then add this method to your code.

- (BOOL)textFieldShouldReturn:(UITextField *)textField {        
    [textField resignFirstResponder];
    return YES;
}

Also add self.textField.delegate = self;

Solution 2

In viewDidLoad declare:

[yourTextField setDelegate:self];

Then, include the override of the delegate method:

-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

Solution 3

Try this in Swift,

Step 1: Set delegate as self to your textField

textField.delegate = self

Step 2: Add this UITextFieldDelegate below your class declaration,

extension YourClassName: UITextFieldDelegate {
    func textFieldShouldReturn(textField: UITextField) -> Bool {
         textField.resignFirstResponder()
        return true
    }
}

Solution 4

In swift do like this:
First in your ViewController implement this UITextFieldDelegate For eg.

class MyViewController: UIViewController, UITextFieldDelegate {
....
}

Now add a delegate to a TextField in which you want to dismiss the keyboard when return is tapped either in viewDidLoad method like below or where you are initializing it. For eg.

override func viewDidLoad() {

    super.viewDidLoad()   
    myTextField.delegate = self
}

Now add this method.

func textFieldShouldReturn(textField: UITextField) -> Bool {

    textField.resignFirstResponder()
    return true
}

Solution 5

Swift 4

Set delegate of UITextField in view controller, field.delegate = self, and then:

extension ViewController: UITextFieldDelegate {
    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        // don't force `endEditing` if you want to be asked for resigning
        // also return real flow value, not strict, like: true / false
        return textField.endEditing(false)
    }
}

The nice thing about Stack Overflow is that MANY questions have already been answered, especially simple ones. Therefore, please look for answers FIRST, before asking. See, it's simple: stackoverflow.com/search?q=iphone+hide+keyboard

[CodeInteractive]

This is a subclass of UITextfield that dynamically change the UIReturnKey according to text/string condition: github.com/codeinteractiveapps/OBReturnKeyTextField

@Felixyz, The first question there is ironically about Android.

[Felixyz]

@IulianOnofrei I suppose that might change from year to year. But it's nice to get a reply one decade later :) Not so nice to discover I wrote such a snarky comment ten years ago. (In my defense, perhaps, it wasn't as clear back then that snark is a rot that perpetually threatens to destroy everything that is nice about the internet.)

[Iulian Onofrei]

@Felixyz, Don't worry, I know the feeling :D

Curious, why is <UITextFieldDelegate> not necessary? Usually you'll see a warning in this case.

[Saurabh]

if you make your file delegate using Interface Builder then <UITextFieldDelegate> is not necessary in .h file..

[Piper]

+1 for the setDelegate: reminder. Definitely had forgotten and code wasn't working previously.

[orafaelreis]

that is not the best practice to do that.

[Clive Jefferies]

Shouldn't this be textField, rather than yourTextField as it is being passed in?

[oscar castellon]

is a way of saying that declare the delegate of your textField

[Umit Kaya]

adding <UITextFieldDelegate> in .h file and set delegate in viewdidload [yourTextField setDelegate:self]; will complete it!

[Umit Kaya]

<UITextFieldDelegate> should be in .h file, otherwise warning will appear!

[hris.to]

Second step not necessery if you set delegate in IB.

[Paul Brewczynski]

@Saurabh What's so special about storyboard created VC?

[lal]

Preferred way if using storyboards.

[Alp Altunel]

needs UITextFieldDelegate in the interface definition.

[Vineesh TP]

@AlpAltunel: Thanks for the comment, It was 4 years back.

[Bryce Sandlund]

Appears (in current versions of Swift) there should be an underscore before "textField:"

[Learn2Code]

how would you handle wanting users to 'tab' to the next text field with the press of the return key, until the last one and then it resigns ? Also in SwiftUI.

[dimpiax]

@Learn2Code make a manager, collect textfields and chain, the last one will trigger finish function.
