Can I create a custom nib for UnknownPersonViewController without using an "undocumented api"?

I'd like to add some custom buttons to an ABUnknownPersonView. Can I use initWithNibName:bundle: in my ABUnknownPersonViewController to load a custom view that I've created in IB, while not using an "undocumented api?" And if I do, how can I make sure that it follows all the properties and responds to all the hooks that the controller e开发者_开发百科xpects?

I typically create all my views programmatically and I generally like the view that ABUnknownPersonViewController creates. I'd rather just start from there. And so I accessed the view and dropped in a button, but with later versions of iOS that broke since that isn't a hook that Apple created.

initWithNibName is also not mentioned in the ABUnknownPersonViewController documentation but it is a method of it's parent class UIViewController. Does that make it safe to use?

You cannot provide a replacement XIB. While I understand you want to avoid it, you will have to use the underlying AddressBook framework and building your own version out of it.

You can, of course, look at open source stuff such as this for a good starting point.
