How to change the keyboard Done button behavior?

Alright, so my goal is that when the keyboard Done button is tapped after introducing something in a UITextField, it should trigger one of my actions but not dismiss the keyboard.

Right now, I've connected the UITextField with my action through the Did End on Exit event and each time I tap the Done button when I'm finished typing, the keyboard goes away.

Let me know if you need further clarification.

In Swift it would be : 

//MARK: UITextFieldDelegate

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

    return true
}

You have to use the delegate method of UITextField. (Set delegate of TextField to correct viewController in Interface Builder or in source)

Then, go to .h file of textField's viewcontroller:

@interface correctViewController(type yours) :UIViewController <UITextFieldDelegate>
//now correctViewController "understands" our textfield.

Go to correctViewController.m file:

//Create delegate method of textField
-(BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder]; //to hide keyboard
    return NO;
}

Looks like this.

Take a look at UITextFieldDelegate Protocol Reference: http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html

You can use this method to control the behavior of your keyboard:

- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
    return NO;
}

Try setting textField.delegate = self in code, as well as conforming to the UITextFieldDelegate protocol. Then implement this method:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    // Do something
}
