iphone - Is it possible to extend an protocol like this? -

I need to add some methods to the representative protocol of my custom UITFixified sub-class, so I put it in the header:

  @protocol MyTextFieldDelegate (UITextFileDelegate) - (zero) text field: (UITextField *) textField; @end  

Is this OK?

In principle, I think it looks fine. The only point I do, I will write something like this:

  @protocol MyTextFieldDelegate (MyTextFieldDelegateExtras) - (zero) text field: (UITextField *) textField; To differ from the methods defined in the  UITextFieldDigital  protocol, go to @end  

.

But actually, if you want to expand the protocol, then use:

  @protocol MyTextFieldDelegate & lt; UITextFieldDelegate & gt; - (zero) text field: (UITextField *) textField; @end
