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:

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.
