如何快速隐藏导航控制器中的后退栏按钮

Question

in the Storyboard (Xcode 6, iOS 8 and swift) i have embedded a TableViewController in a Navigation Controller.

From the object library, i have drag & drop a Bar Button Item as the back button and it show an icon image: when i click that button i show a setting view.

How can i hide that button? In the viewDidLoad() i've tried:

self.navigationItem.hidesBackButton = true;

The code is executed (i've tried with the debugger) but the button is always visible.

If the bar button item is on the right side of the navigation bar you have to set

self.navigationItem.rightBarButtonItems = []

if the bar button item in question is on the left side do the same, it will remove the bar button items from the navigation item

Try this,

self.navigationItem.setLeftBarButtonItem(nil, animated: true)
