Lack of the deterministic way to get a UINavigationButton

[trofima]

Description

There is no good way to get UINavigationButton which has no any label, but using index. But this way is dangerous because an order of the elements isn't guarantied.

[LeoNatan]

This is a known limitation in iOS, and there really isn't a very good way to do it there either.
