Answer 1

It’s quite simple to subclass a UINavigationController through inheritance. It’s a key concept of OOP.

//YourClass.h
@interface YourClass : UINavigationController

@end
//YourClass.m
@implementation YourClass

@end

But

This class is generally used as-is but may be subclassed in iOS 6 and later.

as written in the Overview of UINavigationController. So you may not be able to subclass a UINavigationController if you are supporting iOS 5 or earlier. Maybe your subclass could not work correctly. You can find a good discussion on this stackoverflow topic.
