How do you dismiss the keyboard when editing a UITextField

Question

I know that I need to tell my UITextField to resign first responder when I want to dismis the keyboard  but I m not sure how to know when the user has pressed the  Done  key on the keyboard  Is there a notification I can watch for

User · Answer

If you connect the DidEndOnExit event of the text field to an action (IBAction) in InterfaceBuilder, it will be messaged when the user dismisses the keyboard (with the return key) and the sender will be a reference to the UITextField that fired the event.

For example:

-(IBAction)userDoneEnteringText:(id)sender
{
    UITextField theField = (UITextField*)sender;
    // do whatever you want with this text field
}

Then, in InterfaceBuilder, link the DidEndOnExit event of the text field to this action on your controller (or whatever you're using to link events from the UI). Whenever the user enters text and dismisses the text field, the controller will be sent this message.

kubi  thanks  Your code worked   Just to be explicit  for newbies like  as you say you have to set the UITextField s delegate to be equal to the ViewController in which the text field resides  You can do this wherever you please  I chose the viewDidLoad method   -  void viewDidLoad           sets the textField delegates to equal this viewController     this allows for the keyboard to disappear after pressing done     daTextField delegate   self

Here s what I had to do to get it to work  and I think is necessary for anyone with a Number Pad for a keyboard  or any other ones without a done button    I changed the UIView in the ViewController to a UIControl  I created a function called   - IBAction backgroundIsTapped  id sender    This was also defined in the  h file   After this  I linked to to the  touch down  bit for the ViewController in Interface Builder   In the  background is tapped  function  I put this        answerField resignFirstResponder     Just remember to change  answerField  to the name of the UITextField you want to remove the keyboard from  obviously make sure your UITextField is defined like below        IBOutlet UITextField    lt nameoftextfieldhere gt     I know this topic probably died a long time ago    but I m hoping this will help someone  somewhere
