Question

this is probably quite simple.. but I don’t know what’s the best practice here.

i have a tabbarcontroller with 4 tabs, 3 of them should be a UINavigationController, the other one should also have the UINavigationBar to it but should not be a nav controller itself.
Now i want to give the UINavigationBar a tint color and an action button. I’d like to do this in the interface builder.
The navBar should always be the same one and i only want to create it once.

But where exactly would i do it? Would i create a .xib file with only the UINavigationBar in it and somehow link to that?

I’m very confused here, most tutorials only discuss the navBar for ONE navController but in my case i need the same bar for different ViewControllers..

NavBar comes with the navigationController or can come seperate. It is a subclass of UIView.

You cannot simply share your navBar with all controllers and the non-navigationController. I mean one instance of a navbar. You cannot even set the navbar for a navigationController. It is only readable.

In my understanding you are trying to make the navbar look the same in every controller, am I right?
So you can for instance subclass a UINavigationController and set it up as you want in the init method and init this subclass to add it to the view.

But what about the non-UINavigationController navBar?
Well, that’s easy: Simply add your subclassed navigationController to that tab. You don’t have to use it as NavController. You simply can add views to his view as to a standard ViewController.
