Question

我想提供一个名为BaseViewController的视图控制器，它应该有导航，以便我可以从BaseViewController导航。我尝试使用以下代码，但它没有帮助

@IBAction func presentBaseViewControllerButtonAction(sender: AnyObject) {

    let baseViewController = getViewControllerInstance("Base", storyboardId: "BaseViewControllerID") as! PostServiceViewController

    self.window = UIWindow(frame: UIScreen.mainScreen().bounds) //error this viewcontroller has no member window
    var navigationController = UINavigationController()
    var mainView = baseViewController(nibName: nil, bundle: nil) 
    navigationController.viewControllers = [mainView]
    self.window!.rootViewController = navigationController
    self.window?.makeKeyAndVisible()

    self.presentViewController(baseViewController, animated: true, completion: nil)
}

我找到了答案。如果还有人为此而苦苦挣扎，那就是

let navigationController = UINavigationController(rootViewController: setupController) navigationController.navigationBarHidden = true self.presentViewController(navigationController, animated: true, completion: nil)

Answer 1

试试这个

self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
var nav = UINavigationController()
var mainView = ViewController(nibName: nil, bundle: nil) //ViewController = Name of your controller
nav.viewControllers = [mainView]
self.window!.rootViewController = nav
self.window?.makeKeyAndVisible()

Answer 2

试试这个

let baseViewController = getViewControllerInstance("Base", storyboardId: "BaseViewControllerID") as! PostServiceViewController
let nav = UINavigationController(rootViewController: baseViewController!)
self.window?.rootViewController = nav

Answer 3

您需要将storyboard id作为ViewController名称

    let next = self.storyboard?.instantiateViewControllerWithIdentifier("DashboardController") as! DashboardController
    self.presentViewController(next, animated: true, completion: nil)

以编程方式在swift中导航viewcontroller
