iOS Xcode keyboard done button function

Question

I just can't make the "Done" button to quit the keyboard.

I used this in my controller.h file

- (IBAction)textFieldDoneEditing:(id)sender;

and this for my controller.m file

- (IBAction)textFieldDoneEditing:(id)sender {
  [sender resignFirstResponer];
}

and I'm mixed up in wiring the .xib part.

Answer 1

Make the controller a delegate of the UITextField/UITextView in IB or from code like textField.delegate = self;

Editted: For this you need to declare the controller a delegate of UITextFieldDelegate/UITextViewDelegate as

@interface Controller : <UITextFieldDelegate> { ...

, then override the method:

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

for UITextField and

-(BOOL)textViewShouldEndEditing:(UITextView *)textView{
    [textView resignFirstResponder];
    return YES;
}

for UITextView
