Restore original back button behavior

Question

In a UIViewController viewDidLoad method I customize icon and behavior of the navigation left button this way:

let backButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.action, target:self, action:#selector(handleBack))
self.navigationItem.leftBarButtonItem = backButton

Is there any way to restore its original appearence and behavior?

No you can't do that, you have only option to have a custom back image which looks similar to the original, and toggle as you need. — iphonic, Nov 15 '16 at 12:08
@zombie: as you know, you can change the left button in the navigation bar. I simply asked if, once "overriden" the original button (with its "go back" functionality) it is possible to restore its behavior — , Nov 15 '16 at 12:52
@iphonic: so, if you want to restore the original behavior, all you have to do is redefine its icon and behavior — , Nov 15 '16 at 12:53
@DeyaEldeen: in my current version of iOS (the latest) there are back buttons with arrow, etc. — , Nov 15 '16 at 12:53

You will have to do it this way:

In viewDidLoad method, add this:

self.navigationItem.hidesBackButton = YES;
let backButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.action, target:self, action:#selector(handleBack))
self.navigationItem.leftBarButtonItem = backButton;

To revert back, do this:

self.navigationItem.leftBarButtonItem = nil;
self.navigationItem.hidesBackButton = NO;

the navigation bar only supports these

I gone through extracting iOS assets assets with this and it was so annoying to calibrate the back button to not look fake even though i used the extracted, my advice is let the navigation controller handle this for you by keeping the back that appears when pushing to stack.

Problem is not always is the case. That is: sometimes, in some viewcontroller, you don't need the back functionality. For example, when a user is logged in, you want to put in that position an icon showing his avatar (when you click that avatar you access a section where the user can edit his profile), etc. – Nov 15 '16 at 13:58
