        self.navigationItem.hidesBackButton = true
}

Answer 1

self.navigationItem.hidesBackButton = YES;

Answer 2

在这个地方

 self.navigationItem.hidesBackButton = true

试试这个

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)

尝试下面的代码，在第一个导航控制器（PushViewController）之后出现的视图控制器上编写此代码。

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

Answer 4

 self.tabBarController!.navigationItem.hidesBackButton = true
