There are a lot of similar questions and answers, but they don't solve the main problem: how to properly add any text field in cocos2d with its workable delegate.
For example if I create UITextfield and simply add it to [[CCDirector sharedDirector] view] then it will call textFieldShouldReturn: method only. No more methods doesn't work, even textViewDidBeginEditing:
I gave the same result with using of separate view and UITextField. I also tried to create a separate UIViewController to use its view with UITextField but it even make my app falling down
My mistake was that UITextFieldDelegate and UITextViewDelegate have some similar mehods, and I used some methods from the second delegate. Example:
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView;
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField;
Of course I wrote (UITextView *)textField at the end.
