How to dismiss keyboard iOS programmatically when pressing return

Question

I created a UITextField programmatically making the UITextField a property of the viewController  I need to dismiss the keyboard with the return and the touch on the screen  I was able to get the screen touch to dismiss  but pressing return is not working  I ve seen how to do it with storyboards and by allocating and initializing the UITextField object directly without creating it as a property  Possible to do   h  import  lt UIKit UIKit h gt    interface ViewController   UIViewController  lt UITextFieldDelegate gt    property  strong  atomic  UITextField  username    end   m  import  quot ViewController h quot    interface ViewController      end   implementation ViewController  -  void viewDidLoad        super viewDidLoad               Do any additional setup after loading the view  typically from a nib           self view backgroundColor    UIColor blueColor       self username     UITextField alloc  initWithFrame CGRectMake 100  25  80  20        self username placeholder     quot Enter your username quot       self username backgroundColor    UIColor whiteColor       self username borderStyle   UITextBorderStyleRoundedRect      if  self username placeholder    nil            self username clearsOnBeginEditing   NO             username delegate   self             self view addSubview self username         username resignFirstResponder           -  void touchesBegan  NSSet   touches withEvent  UIEvent   event      NSLog   quot touchesBegan withEvent  quot         self view endEditing YES        super touchesBegan touches withEvent event       end

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

Try to get an idea about what a first responder is in iOS view hierarchy  When your textfield becomes active or first responder  when you touch inside it  or pass it the messasge becomeFirstResponder programmatically   it presents the keyboard  So to remove your textfield from being the first responder  you should pass the message resignFirstResponder to it there    textField resignFirstResponder     And to hide the keyboard on its return button  you should implement its delegate method textFieldShouldReturn  and pass the resignFirstResponder message   -  BOOL textFieldShouldReturn  UITextField   textField       textField resignFirstResponder       return YES
