Easy way to dismiss keyboard?

I have quite a few controls scattered throughout many table cells in my table, and I was wondering if there's an easier way to dismiss the keyboard without having to loop through all my controls and resigning them all as the first responder. I guess the question is.. How would I get the current first responder to the keyboard?

Try:

[self.view endEditing:YES];

You can force the currently-editing view to resign its first responder status with [view endEditing:YES]. This hides the keyboard.

Unlike -[UIResponder resignFirstResponder], -[UIView endEditing:] will search through subviews to find the current first responder. So you can send it to your top-level view (e.g. self.view in a UIViewController) and it will do the right thing.

(This answer previously included a couple of other solutions, which also worked but were more complicated than is necessary. I've removed them to avoid confusion.)

You can send a nil targeted action to the application, it'll resign first responder at any time without having to worry about which view currently has first responder status.

Objective-C:

[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];

Swift 3.0:

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

Nil targeted actions are common on Mac OS X for menu commands, and here's a use for them on iOS.

To be honest, I'm not crazy about any of the solutions proposed here. I did find a nice way to use a TapGestureRecognizer that I think gets to the heart of your problem: When you click on anything besides the keyboard, dismiss the keyboard.

1. In viewDidLoad, register to receive keyboard notifications and create a UITapGestureRecognizer:

    NSNotificationCenter *nc = [NSNotificationCenter defaultCenter];
   
    [nc addObserver:self selector:@selector(keyboardWillShow:) name:
    UIKeyboardWillShowNotification object:nil];
   
    [nc addObserver:self selector:@selector(keyboardWillHide:) name:
    UIKeyboardWillHideNotification object:nil];
    	
    tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self
    action:@selector(didTapAnywhere:)];
   

2. Add the keyboard show/hide responders. There you add and remove the TapGestureRecognizer to the UIView that should dismiss the keyboard when tapped. Note: You do not have to add it to all of the sub-views or controls.

    -(void) keyboardWillShow:(NSNotification *) note {
        [self.view addGestureRecognizer:tapRecognizer];
    }
   
    -(void) keyboardWillHide:(NSNotification *) note
    {
        [self.view removeGestureRecognizer:tapRecognizer];
    }
   

3. The TapGestureRecognizer will call your function when it gets a tap and you can dismiss the keyboard like this:

    -(void)didTapAnywhere: (UITapGestureRecognizer*) recognizer {    
        [textField resignFirstResponder];
    }
   

The nice thing about this solution is that it only filters for Taps, not swipes. So if you have scrolling content above the keyboard, swipes will still scroll and leave the keyboard displayed. By removing the gesture recognizer after the keyboard is gone, future taps on your view get handled normally.

This is a solution to make the keyboard go away when hit return in any textfield, by adding code in one place (so don't have to add a handler for each textfield):

---

consider this scenario:

i have a viewcontroller with two textfields (username and password). and the viewcontroller implements UITextFieldDelegate protocol

i do this in viewDidLoad

- (void)viewDidLoad 
{
	[super viewDidLoad];
	
	username.delegate = self;
	password.delegate = self;
}

and the viewcontroller implements the optional method as

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

and irrespective of the textfield you are in, as soon as i hit return in the keyboard, it gets dismissed!

In your case, the same would work as long as you set all the textfield's delegate to self and implement textFieldShouldReturn

A better approach is to have something "steal" first responder status.

Since UIApplication is a subclass of UIResponder, you could try:

[[UIApplication sharedApplication] becomeFirstResponder]
[[UIApplication sharedApplication] resignFirstResponder]

Failing that, create a new UITextField with a zero sized frame, add it to a view somewhere and do something similar (become followed by resign).

Tuck this away in some utility class.

+ (void)dismissKeyboard {
    [self globalResignFirstResponder];
}

+ (void) globalResignFirstResponder {
    UIWindow * window = [[UIApplication sharedApplication] keyWindow];
    for (UIView * view in [window subviews]){
        [self globalResignFirstResponderRec:view];
    }
}

+ (void) globalResignFirstResponderRec:(UIView*) view {
    if ([view respondsToSelector:@selector(resignFirstResponder)]){
        [view resignFirstResponder];
    }
    for (UIView * subview in [view subviews]){
        [self globalResignFirstResponderRec:subview];
    }
}

@Nicholas Riley & @Kendall Helmstetter Geln & @cannyboy:

Absolutely brilliant!

Thank you.

Considering your advice and the advice of others in this thread, this is what I've done:

What it looks like when used:

[[self appDelegate] dismissKeyboard]; (note: I added appDelegate as an addition to NSObject so I can use anywhere on anything)

What it looks like under the hood:

- (void)dismissKeyboard 
{
    UITextField *tempTextField = [[[UITextField alloc] initWithFrame:CGRectZero] autorelease];
    tempTextField.enabled = NO;
    [myRootViewController.view addSubview:tempTextField];
    [tempTextField becomeFirstResponder];
    [tempTextField resignFirstResponder];
    [tempTextField removeFromSuperview];
}

EDIT

Amendment to my answer to included tempTextField.enabled = NO;. Disabling the text field will prevent UIKeyboardWillShowNotification and UIKeyboardWillHideNotification keyboard notifications from being sent should you rely on these notifications throughout your app.

Quick tip on how to dismiss the keyboard in iOS when a user touches anywhere on the screen outside of the UITextField or keyboard. Considering how much real estate the iOS keyboard can take up, it makes sense to have an easy and intuitive way for your users to dismiss the keyboard.

Here's a link

A lot of overly-complicated answers here, perhaps because this is not easy to find in the iOS documentation. JosephH had it right above:

[[view window] endEditing:YES];

Here's what I use in my code. It works like a charm!

In yourviewcontroller.h add:

@property (nonatomic) UITapGestureRecognizer *tapRecognizer;

Now in the .m file, add this to your ViewDidLoad function:

- (void)viewDidLoad {
    //Keyboard stuff
    tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapAnywhere:)];
    tapRecognizer.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tapRecognizer];
}

Also, add this function in the .m file:

- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
    [self.view endEditing:YES];
}

Even Simpler than Meagar's answer

overwrite touchesBegan:withEvent:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [textField resignFirstResponder];`
}

This will dismiss the keyboard when you touch anywhere in the background.

You should send endEditing: to working window being the subclass of UIView

[[UIApplication sharedApplication].windows.firstObject endEditing:NO];

In your view controller's header file add <UITextFieldDelegate> to the definition of your controller's interface so that it conform to the UITextField delegate protocol...

@interface someViewController : UIViewController <UITextFieldDelegate>

... In the controller's implementation file (.m) add the following method, or the code inside it if you already have a viewDidLoad method ...

- (void)viewDidLoad
{
    // Do any additional setup after loading the view, typically from a nib.
    self.yourTextBox.delegate = self;
}

... Then, link yourTextBox to your actual text field

- (BOOL)textFieldShouldReturn:(UITextField *)theTextField 
{
    if (theTextField == yourTextBox) {
        [theTextField resignFirstResponder];
    }
    return YES;
}

The best way to dismiss keyboard from UITableView and UIScrollView are:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag

In swift 3 you can do the following

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

Jeremy's answer wasn't quite working for me, I think because I had a navigation stack in a tab view with a modal dialog on top of it. I'm using the following right now and it is working for me, but your mileage may vary.

 // dismiss keyboard (mostly macro)
[[UIApplication sharedApplication].delegate dismissKeyboard]; // call this in your to app dismiss the keybaord

// --- dismiss keyboard (in indexAppDelegate.h) (mostly macro)
- (void)dismissKeyboard;

// --- dismiss keyboard (in indexAppDelegate.m) (mostly macro)
// do this from anywhere to dismiss the keybard
- (void)dismissKeyboard {    // from: http://stackoverflow.com/questions/741185/easy-way-to-dismiss-keyboard
    
    UITextField *tempTextField = [[UITextField alloc] initWithFrame:CGRectZero];
    
    UIViewController *myRootViewController = <#viewController#>; // for simple apps (INPUT: viewController is whatever your root controller is called.  Probably is a way to determine this progragrammatically)
    UIViewController *uivc;
    if (myRootViewController.navigationController != nil) { // for when there is a nav stack
        uivc = myRootViewController.navigationController;
    } else {
        uivc = myRootViewController;
    }
    
    if (uivc.modalViewController != nil) { // for when there is something modal
        uivc = uivc.modalViewController;
    } 
    
    [uivc.view  addSubview:tempTextField];
    
    [tempTextField becomeFirstResponder];
    [tempTextField resignFirstResponder];
    [tempTextField removeFromSuperview];
    [tempTextField release];
    
}

You may also need to override UIViewController disablesAutomaticKeyboardDismissal to get this to work in some cases. This may have to be done on the UINavigationController if you have one.

Subclass your textfields... and also textviews

In the subclass put this code..

-(void)conformsToKeyboardDismissNotification{
    
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(dismissKeyBoard) name:KEYBOARD_DISMISS object:nil];
}

-(void)deConformsToKeyboardDismissNotification{
    
    [[NSNotificationCenter defaultCenter] removeObserver:self name:KEYBOARD_DISMISS object:nil];
}

- (void)dealloc{
    [[NSNotificationCenter defaultCenter] removeObserver:self];
    [self resignFirstResponder];
}

In the textfield delegates (similarly for textview delegates)

-(void)textFieldDidBeginEditing:(JCPTextField *)textField{
     [textField conformsToKeyboardDismissNotification];
}


- (void)textFieldDidEndEditing:(JCPTextField *)textField{
    [textField deConformsToKeyboardDismissNotification];
}

All set.. Now just post the notification from anywhere in your code. It will resign any keyboard.

And in swift we can do

UIApplication.sharedApplication().sendAction("resignFirstResponder", to: nil, from: nil, forEvent: nil)

To dismiss a keyboard after the keyboard has popped up, there are 2 cases,

1. when the UITextField is inside a UIScrollView

2. when the UITextField is outside a UIScrollView

2.when the UITextField is outside a UIScrollView override the method in your UIViewController subclass

you must also add delegate for all UITextView

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.view endEditing:YES];
}

1. In a scroll view, Tapping outside will not fire any event, so in that case use a Tap Gesture Recognizer, Drag and drop a UITapGesture for the scroll view and create an IBAction for it.

to create a IBAction, press ctrl+ click the UITapGesture and drag it to the .h file of viewcontroller.

Here I have named tappedEvent as my action name

- (IBAction)tappedEvent:(id)sender {
      [self.view endEditing:YES];  }

I hate that there's no "global" way to programmatically dismiss the keyboard without using private API calls. Frequently, I have the need to dismiss the keyboard programmatically without knowing what object is the first responder. I've resorted to inspecting the self using the Objective-C runtime API, enumerating through all of its properties, pulling out those which are of type UITextField, and sending them the resignFirstResponder message.

It shouldn't be this hard to do this...

It's not pretty, but the way I resign the firstResponder when I don't know what that the responder is:

Create an UITextField, either in IB or programmatically. Make it Hidden. Link it up to your code if you made it in IB. Then, when you want to dismiss the keyboard, you switch the responder to the invisible text field, and immediately resign it:

  [self.invisibleField becomeFirstResponder];
  [self.invisibleField resignFirstResponder];

You can recursively iterate through subviews, store an array of all UITextFields, and then loop through them and resign them all.

Not really a great solution, especially if you have a lot of subviews, but for simple apps it should do the trick.

I solved this in a much more complicated, but much more performant way, but using a singleton/manager for the animation engine of my app, and any time a text field became the responder, I would assign assign it to a static which would get swept up (resigned) based on certain other events... its almost impossible for me to explain in a paragraph.

Be creative, it only took me 10 minutes to think through this for my app after I found this question.

the easist way is to call the method

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
	if(![txtfld resignFirstResponder])
    {
		[txtfld resignFirstResponder];
    }
    else
	{

	}
    [super touchesBegan:touches withEvent:event];
}

A slightly more robust method I needed to use recently:

- (void) dismissKeyboard {
	NSArray *windows = [UIApplication sharedApplication].windows;
	
	for(UIWindow *window in windows) [window endEditing:true];

	//	Or if you're only working with one UIWindow:

	[[UIApplication sharedApplication].keyWindow endEditing:true];
}

I found some of the other "global" methods didn't work (for example, UIWebView & WKWebView refused to resign).

Add A Tap Gesture Recognizer to your view.And define it ibaction

your .m file will be like

    - (IBAction)hideKeyboardGesture:(id)sender {
    NSArray *windows = [UIApplication sharedApplication].windows;
    for(UIWindow *window in windows) [window endEditing:true];
    [[UIApplication sharedApplication].keyWindow endEditing:true];
}

It's worked for me

Yes, endEditing is the best option. And From iOW 7.0, UIScrollView has a cool feature to dismiss the keyboard on interacting with the scroll view. For achieving this, you can set keyboardDismissMode property of UIScrollView.

Set the keyboard dismiss mode as:

tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag

It has few other types. Have a look at this apple document.

In swift :

self.view.endEditing(true)

You have to use one of these methods,

[self.view endEditing:YES];

or

[self.textField resignFirstResponder];

Update

I found another simple way

simply declare a property :-

@property( strong , nonatomic) UITextfield *currentTextfield;

and a Tap Gesture Gecognizer:-

@property (strong , nonatomic) UITapGestureRecognizer *resignTextField;

In ViewDidLoad

_currentTextfield=[[UITextField alloc]init];
_resignTextField=[[UITapGestureRecognizer alloc]initWithTarget:@selector(tapMethod:)];

[self.view addGestureRecognizer:_resignTextField];

Implement the textfield delegate method didBeginEditing

 -(void)textFieldDidBeginEditing:(UITextField *)textField{

     
      _currentTextfield=textField;
      
    }

Implement Your Tap Gesture Method (_resignTextField)

 -(void)tapMethod:(UITapGestureRecognizer *)Gesture{

     [_currentTextfield resignFirstResponder];

 }
