Answer 1

1.Define the done button (= return key):

textField.returnKeyType = UIReturnKeyDone;

2.Add the action-listener:

[textField addTarget:self action:@selector(textFieldDoneEditing:) forControlEvents:UIControlEventEditingDidEndOnExit];

3.Define the action-event:

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

Have fun!

EDIT:

Here you can find detailed instructions how to add a Toolbar with Next & Previous above UITextField Keyboard: http://www.randomsequence.com/articles/adding-a-toolbar-with-next-previous-above-uitextfield-keyboard-iphone/

EDIT2:

Now, I have a really great example for you: "This view extends UITextView adding on top of the keyboard associated with this UITextView a toolbar with a « Done » Button"

I check the code and it is a lot of easier than the first example:

EDIT3:

Hmmm, no, I doesn't test to code. But I will test it now!

1.Problem: the right initialization. If I add the UITextView in IB, initWithCoder gets called:

- (id)init {

    NSLog(@"init");

    if (self = [super init]) {
        //register a specific method on keyboard appearence
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    }
    return self;
}

- (id)initWithCoder:(NSCoder *)decoder {

    NSLog(@"initWithCoder");

    if (self = [super initWithCoder:decoder]) {
        //register a specific method on keyboard appearence
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    }
    return self;
}

- (id)initWithFrame:(CGRect)frame {

    NSLog(@"initWithFrame");

    if (self = [super initWithFrame:frame]) {
        //register a specific method on keyboard appearence
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    }
    return self;
} 

2.Problem: There's no view with the the Prefix "UIKeyboard":

for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) {
    NSLog(@"keyboardWindow = %@", keyboardWindow);
    for (UIView *keyboard in [keyboardWindow subviews]) {
        NSLog(@"keyboard = %@", keyboard);

            if([[keyboard description] hasPrefix:@"<UIKeyboard"] == YES) {
                // THERE'S NO VIEW 'UIKeyboard'!!!
            }

    }
}

The code doesn't work, I'm sorry... I don't know why there's no view "UIKeyboard"... Maybe the first example will help you at this point and you can build your own solution.
