将自定义uinavigationbar与uinavigationcontroller一起使用时,请删除“后退”按钮

当我用自定义uinavigationbar初始化uinavigationcontroller时,我很难找到删除“ghost”后退按钮(只有一个蓝色的返回箭头)的方法。当我点击后退按钮时,我会看到我的自定义导航栏,但我不想点击后退按钮。

我已经尝试了几乎所有其他的解决方案,包括setHidesBackButton等,并按照调用这些函数的顺序进行了处理。

class TabsVC : UITabBarController {

func setupTabBar() {
    // setup feed tab
    let navVC = UINavigationController(navigationBarClass: NavBar.self, toolbarClass: nil)

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

    let feedVC = FeedVC()
    navVC.pushViewController(feedVC, animated: false)
    let feedIcon = UIImage.fontAwesomeIcon(name: .home, textColor: ColorConstants.baseColor, size: CGSize(width: 40, height: 40))
    navVC.tabBarItem = UITabBarItem(title: "", image: feedIcon, tag: 1)

    // other tabs stuff
}

class NavBar : UINavigationBar {

func prepare() {
    let item = UINavigationItem(title: "")
    let titleV = titleView()
    item.titleView = titleV

    item.hidesBackButton = true
    item.setHidesBackButton(false, animated: false)

    item.leftBarButtonItem = UIBarButtonItem(image: UIImage.fontAwesomeIcon(name: .userCircle, textColor: ColorConstants.baseColor, size: CGSize(width: 40, height: 40)), style: .plain, target: nil, action: nil)
    item.leftBarButtonItem?.tintColor = .white
    item.leftBarButtonItem?.action = #selector(moveToProfileScreen)
    self.pushItem(item, animated: false)
}
