Call on your ViewDidLoad the following method:

or

<pre><code>self.navigationItem.hidesBackButton = YES;

Swift:

I found that this was caused by pushing a new view in viewWillAppear, if I moved it to viewDidAppear then the back button didn't show. Strange that this issue only appeared in iOS8.

 NSString *name = [NSString stringWithFormat:@"%@",view.class];

Where have you written that code?

It should be as simple as in your view controller's loadView/viewDidLoad: method adding this

<pre><code>[self.navigationItem setHidesBackButton:YES];
</code></pre>

This works for me on an iPhone 6

Try to use <code>self.navigationItem.hidesBackButton = true</code> in <code>viewWillAppear()</code> method, this worked for me.

Hiding the back button using setHidesBackButton only works if you have not customized the button.

From the method reference: "Specify true if the back button should be hidden when this navigation item is the top item. Specify false if the back button should be visible, assuming it has not been replaced by a custom item."
(Note the last line)

The simply solution in that case is to first set the leftBarButtonItem to nil.

Swift 3.0:

<pre><code>self.navigationItem.leftBarButtonItem = nil
self.navigationItem.setHidesBackButton(true, animated: false)
</code></pre>

blocks|key|5433583|text|此错误仅在使用Storyboard时才会发生。另一个解决方案是添加一个空标题的UIBarButtonItem来“伪造”它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5433584|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This bug only happens when you use Storyboard. Another solution is add an UIBarButtonItem with empty title to "fake" it.

blocks|key|318695|text|我找到的唯一方法是隐藏导航条，并在情节提要中添加导航条，并在下一个ViewController中重新显示导航条。我所要做的就是在状态栏中添加一个标签，以便导航栏是统一的。我没有别的办法..。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|318696|​|318697|📷|atomic|offset|length|318698|318699|-+(void)viewWillAppear:(BOOL)animated

The only way I've found to do this is to hide the navigation bar and adding a navigation bar in storyboard and redisplay the navigation bar in the next ViewController. All I had to do is add a label in the status bar so that the navigation bar is uniform. I have found no other way...

<img src="https://i.stack.imgur.com/WPIxb.png" alt="screen">

<pre><code>- (void)viewWillAppear:(BOOL)animated
{
 [super viewWillAppear:YES];
 [[self navigationController] setNavigationBarHidden:YES animated:YES];
}
</code></pre>

so that the navigation bar is displayed in the next viewcontroller, declare in:

<pre><code>- (void)viewWillDisappear:(BOOL)animated
{
 [[self navigationController] setNavigationBarHidden:NO animated:YES];

}
</code></pre>

After I run my application in iOS 8 (XCode 6.0.1, iPhone 6), the back button does not hide.

My code:

<pre><code>- (void)removeCategoriesButton
{
 if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
 [_navigationController.topViewController.navigationItem setHidesBackButton:YES];
 [_navigationController.topViewController.navigationItem setLeftBarButtonItem:nil];
 } else {
 UIViewController *controller = _app.window.rootViewController;

 if ([controller isKindOfClass:[UINavigationController class]]) {
 UINavigationController *nav = (UINavigationController *)controller;
 [nav.topViewController.navigationItem setHidesBackButton:YES];
 [nav.topViewController.navigationItem setLeftBarButtonItem:nil];
 }
 }
}
</code></pre>

But the back button does not hide (see screenshot):

<img src="https://i.stack.imgur.com/RkQv5.png" alt="Simulator screen">

UPD:

I run application in another simulators, and i see this "bug" only on iOS 8.
