ios - 从 App Delegate 推送 View Controller

Question

我正在尝试呈现并推送到另一个 Storyboard文件中的 View Controller 。但我不能忘记显示 TabBar，这里是我的代码和我如何设置它的屏幕截图。

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
    let rootView = self.window!.rootViewController as! TabBarViewController
    rootView.selectedIndex = 4
    let storyBoard = UIStoryboard(name: "Main", bundle: nil)
    let navVC = storyBoard.instantiateViewControllerWithIdentifier("moreNav") as! UINavigationController
    storyBoard.instantiateViewControllerWithIdentifier("moreView") as! MoreTableViewController
    let vc = navVC.visibleViewController as! MoreTableViewController


    let pdfLockerSB = UIStoryboard(name: "PDFLocker", bundle: nil)
    let pdfvc = pdfLockerSB.instantiateViewControllerWithIdentifier("pdfLockerTable") as! PDFLockerTableViewController

    vc.navigationController?.pushViewController(pdfvc, animated: true)

    return true
}

知道我做错了什么吗？它是一个 UITabBarController 链接到一个 UINavigationController 链接到一个 UITableViewController。

我已经设置好 segue，但我不确定为什么它不执行。使用推送或执行

Answer 1

试试这个

let navVC: UINavigationController =  rootView.viewControllers![4] as! UINavigationController;
let vc = navVC.topViewController as! MoreTableViewController

代替

let navVC = storyBoard.instantiateViewControllerWithIdentifier("moreNav") as! UINavigationController
let vc = navVC.visibleViewController as! MoreTableViewController
