Question

我试图在UINavigationController中推送TabBarController但是只要我按下显示器没有导航栏的第一个控制器，只要我使用标签栏按钮在其他屏幕上导航它显示，我尝试在标签栏的登录页面上手动添加它，如下所示：

    self.navigationController?.navigationController?.setNavigationBarHidden(false, animated: false)
    let barItem = UIBarButtonItem(image: UIImage(named: "upload"), style: UIBarButtonItemStyle.Plain, target: self, action: Selector("cameraTap"))
    self.navigationController?.navigationBar.topItem?.rightBarButtonItem = barItem
    self.navigationController?.navigationBar.topItem?.title = "welcome to the jungle"

这就是我调用TabBarController的方式

func startApp(){
    let sb = UIStoryboard(name: "Main", bundle: nil)
    let overviewVC = sb.instantiateViewControllerWithIdentifier("TabBarController") as! UITabBarController
    overviewVC.navigationItem.setHidesBackButton(true, animated: false)
    if logInController != nil{
        logInController.dismissViewControllerAnimated(true, completion: nil)
    }
    overviewVC.selectedIndex = 0
    self.navigationController?.pushViewController(overviewVC, animated: true)
}

我也尝试将它分配给self.navigationController.tabBarController，但它似乎只是读取到目前为止没有运气。

查看组织：

Nav Contr -> View Contr -> Tab Contr -> View Contr 1
                                     -> View Contr 2
                                     -> View Contr 3
