        self.tabBarController!.navigationItem.rightBarButtonItem = UIBarButtonItem(title:"Cart", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
         self.tabBarController!.navigationItem.leftBarButtonItem = UIBarButtonItem(title:"Cart", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
        // Do any additional setup after loading the view.
        self.navigationItem.hidesBackButton = true
}

Answer 1

在这个地方

 self.navigationItem.hidesBackButton = true

尝尝这个

self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: UIView())

选项-2

 self.tabbarcontroller.navigationcontroller.navigationitem.hidesBackButton = true
self.tabBarController!.navigationItem.rightBarButtonItem = UIBarButtonItem(title:"Cart", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
self.tabBarController!.navigationItem.leftBarButtonItem = UIBarButtonItem(title:"Cart", style: UIBarButtonItemStyle.Plain, target: self, action: nil)

Answer 2

self.navigationItem.hidesBackButton = YES;

Answer 3

尝试使用下面的代码，在第一个导航控制器( PushViewController )之后出现的视图控制器上编写这段代码。

self.navigationItem.setHidesBackButton(true, animated: false)
