swift - 快速以编程方式导航 View Controller

Question

我想展示一个名为 BaseViewController 的 View Controller ，它应该具有导航功能，以便我可以从 BaseViewController 进行导航。我已尝试使用以下代码，但没有帮助

@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。如果有人仍在为此苦苦挣扎，这里就是

让 navigationController = UINavigationController(rootViewController: setupController)
导航 Controller .navigationBarHidden = true
self.presentViewController(navigationController，动画:true，完成:nil)

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()
