在所有视图上添加导航栏。 迅速

Question

This is a basic question, but I couldn't really find a answer.
In my swift app, I decide to add navigation bar on all the view controller in storyboard.

Do I have to manually add in the bar for each of them, or is there any clean way I could add them in automatically/programmatically only once?
(I just want to add the bar with title, not even the buttons or the navigation function.)

Thank you in advance!

Answer 1

Yeah, the Navigation Controller puts a navigation bar on every one in your storyboard. Just drag one onto your storyboard, connect your first controller as the root to it, and make every following view controller connected by "Show" segues to the last. Now all your view controllers should have a navigation bar on top of them.

You can access their navigation controller with this property in a view controller:

self.navigationController

Take a look at this tutorial , it'll give you more details on how navigation controllers / view controller hierarchy works.

Answer 2

Yes you will have to manually add the custom bar to each of them.

However, you can make it cleaner by defining a class for that custom view. For example HeaderBar then you do all the setup in this class itself ( HeaderBar.swift ). When you add this bar to any view controller, all you need to do is simply drag and drop from storyboard and typing class name HeaderBar and it is ready to go, no more further configuration.
