How to make a common class for UINavigationController barbutton item actions?

Question

In my app, i need to have a UINavigationController which will have different navigation bar in different view controllers and based on that it will have different UIBarButton items which will required different actions.

Currently what i have is a navigation controller and i am customizing it where ever required and if there are any buttons i need to add i am writing its action method in the same class. But at many places the action is similar so i want to create a common controller for this. i know this is the inefficient way so i was thinking if somebody can guide me on how to make it more productive.

Thanks,

Configuring the bar button item in a UIViewController base class is the right way to go.

In the base class:

// Configure button.
button.target = self;
button.action = @selector(action:);


// Implement common action.
- (void)action:(id)sender {
    …
}

In subclass with special action:

// Implement special action.
- (void)action:(id)sender {
    …
}
