Answer 1

See Managing the Keyboard for a complete discussion on this topic.

Answer 2

When the return key is pressed, call:

[uitextfield resignFirstResponder];

Answer 3

in swift you should delegate UITextfieldDelegate, its important don't forget it, in the viewController, like:

class MyViewController: UITextfieldDelegate{

     mytextfield.delegate = self

     func textFieldShouldReturn(textField: UITextField) -> Bool {
          textField.resignFirstResponder()
     }
}

Answer 4

You can add an IBAction to the uiTextField(the releation event is "Did End On Exit"),and the IBAction may named hideKeyboard,

-(IBAction)hideKeyboard:(id)sender
{
    [uitextfield resignFirstResponder];
}

also,you can apply it to the other textFields or buttons,for example,you may add a hidden button to the view,when you click it to hide the keyboard.

Answer 5

Implement the UITextFieldDelegate method like this:

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

Answer 6

Set the Delegate of the UITextField to your ViewController, add a referencing outlet between the File's Owner and the UITextField, then implement this method:

-(BOOL)textFieldShouldReturn:(UITextField *)textField 
{
   if (textField == yourTextField) 
   {
      [textField resignFirstResponder]; 
   }
   return NO;
}
