UINavigationBar custom back button without title

It's actually pretty easy, here is what I do:

Objective C

// Set this in every view controller so that the back button displays back instead of the root view controller nameself.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];

Swift 2

self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .Plain, target: nil, action: nil)

Swift 3

self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)

Put this line in the view controller that is pushing on to the stack (the previous view controller). The newly pushed view controller back button will now show whatever you put for initWithTitle, which in this case is an empty string.

I found an easy way to make my back button with iOS single arrow.

Let's supouse that you have a navigation controller going to ViewA from ViewB. In IB, select ViewA's navigation bar, you should see these options: Title, Prompt and Back Button.

ViewA navigate bar options

The trick is choose your destiny view controller back button title (ViewB) in the options of previous view controller (View A). If you don't fill the option "Back Button", iOS will put the title "Back" automatically, with previous view controller's title. So, you need to fill this option with a single space.

Fill space in "Back Button" option

The Result:

Just use an image!

OBJ-C:

- (void)viewDidLoad {     [super viewDidLoad];     UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"Icon-Back"]                                                                                        style:UIBarButtonItemStylePlain                                                                                       target:self.navigationController                                                                                       action:@selector(popViewControllerAnimated:)];     self.navigationItem.leftBarButtonItem = backButton;}

SWIFT 4:

let backBTN = UIBarButtonItem(image: UIImage(named: "Back"),                               style: .plain,                               target: navigationController,                               action: #selector(UINavigationController.popViewController(animated:)))navigationItem.leftBarButtonItem = backBTNnavigationController?.interactivePopGestureRecognizer?.delegate = self
