将此代码添加到视图控制器中

UIView *myView = [[UIView alloc] initWithFrame: CGRectMake(0, 0, 300, 30)];
UIBarButtonItem *btnL = [[UIBarButtonItem alloc]initWithCustomView:myView];
self.navigationItem.leftBarButtonItem = btnL;

objective - c: self.navigationItem.hidesBackButton = YES;

迅速: navigationItem。hidesBackButton = true

最好的方法是将它们结合起来，所以即使你手动设置它，它也会隐藏后退按钮:

self.navigationItem.leftBarButtonItem=nil;
self.navigationItem.hidesBackButton=YES;

navigationItem.leftBarButtonItem = nil
navigationItem.hidesBackButton = true

如果你在didLoad或loadView中使用这个代码块，但工作不完美。İf你仔细看，你可以看到后退按钮隐藏时，你的视图加载。看起来很奇怪。

完美的解决方案是什么?

从componentView (Command + Shift + L)添加BarButtonItem组件到你的目标viewControllers导航栏。

从右侧面板选择BarButtonItem set Title = " "

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

迅速:

将此添加到控制器中

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.setHidesBackButton(true, animated: false)
}
