Easy way to dismiss keyboard

Question

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

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

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

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

Nicholas Riley  amp   Kendall Helmstetter Geln  amp   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

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

To dismiss a keyboard after the keyboard has popped up  there are 2 cases    when the UITextField is inside a UIScrollView  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        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        the abouve given Information was derived from the following link  please refer for more information or contact me if you dont understand the abouve data   http   samwize com 2014 03 27 dismiss-keyboard-when-tap-outside-a-uitextfield-slash-uitextview

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 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

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

Even Simpler than Meagar s answer  overwrite touchesBegan withEvent    -  void touchesBegan  NSSet   touches withEvent  UIEvent   event        textField resignFirstResponder        This will dismiss the keyboardwhen you touch anywhere in the background

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

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

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

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

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     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      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      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
