UINavigationController Back button doesn't hide title on iOS 11

Question

I've updated my device to iOS 11 Beta yesterday and my app using this code in AppDelegate for hide back button title on all screen:

@implementation UINavigationItem (Customization)

/**
 Removes text from all default back buttons so only the arrow or custom image shows up.
 */
-(UIBarButtonItem *)backBarButtonItem
{
    return [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
}

It's working normally on older version but when I run my app on iOS 11 Beta, the title of back button still shown. Does anyone face this problem? Is it a beta version bug of iOS or iOS 11 need another way to hide the back button title?

I've been using your approach previously, but unfortunately it's not working any more. After trying all possible solutions, that's the only thing that I found working without any issues and bugs. Please note, that it seems that there's no more a universal way to fix this globally for all UIViewControllers.

Call

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:self.navigationItem.backBarButtonItem.style target:nil action:nil];

on viewWillDisappear of the presenting controller.

Call
```
self.title = @"Title"
```

on viewWillAppear of the presenting controller.

Other solutions that I have tried have various issues, e.g. they are working fine but everything breaks when you swipe from left edge a bit.

Yeah, I though iOS 11 need a different way to hide back button title. So I was remove my old code then used custom button instead. At this time, it's working without any issues and bugs too. – Bad_Developer Aug 08 '17 at 09:08
Thank you for this solution. This is the only solution that works in iOS 11. iOS 11 broke so many things in our app. – coolcool1994 Sep 29 '17 at 01:56
Make sure you do this on the viewController it's referring to from the back button, not the one you're segueing into. – Lucas van Dongen Oct 30 '17 at 00:41

What I did in iOS 11 was simply to implement the UINavigationControllerDelegate protocol for my root navigation controllers and to set the "blank" UIBarButtonItem as back button everytime a new controller will be displayed. Here is the Swift 4 version:

func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
    viewController.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
}

Setting the bar button title text color to clear is the cleanest way I've found to apply for all screens

 UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.clear], for: .normal)
 UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.clear], for: .highlighted)

FOR SWIFT 3+

Use below code to support iOS 9 to 11

     if #available(iOS 11, *) {
            UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.clear], for: .normal)
            UIBarButtonItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.clear], for: .highlighted)
     } else {
            UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(0,
-60), for:UIBarMetrics.default)
        }

This sets all bar button items to clear, probably not what most people are looking for — john_ryan, Nov 17 '17 at 23:24
