使用swift从app delegate打开视图控制器 [英] Opening view controller from app delegate using swift

问题描述

我正在尝试创建推送通知，根据从推送中获得的信息确定要打开的视图。

I am trying to create a push notification which determines which view to open according to information obtained from the push.

我已设法从推送中获取信息，但我现在正努力让视图开启

I have managed to get the information from the push, but I am now struggling to get the view to open

查看其他堆栈溢出问题我目前有以下内容：

Looking at other stack overflow questions I have the following currently:

App Delegate完成加载：

App Delegate Did finish loading:

     //Extract the notification data
    if let notificationPayload = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {
        // Get which page to open
        let viewload = notificationPayload["view"] as? NSString
        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
        //Load correct view
        if viewload == "circles" {

            var viewController = self.window?.rootViewController?.storyboard?.instantiateViewControllerWithIdentifier("Circles") as! UIViewController
            self.window?.rootViewController = viewController

                        }
    }

目前这在var ViewController = self ... line上失败。

Currently this is failing on the var ViewController = self... line.

推荐答案

你必须设置ViewController StoryBoardId属性如下图所示。

You have to set ViewController StoryBoardId property as below image.

在swift中使用以下编码打开viewController

open viewController using coding as below in swift

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

         let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
         let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewControllerWithIdentifier("Circles") as UIViewController
         self.window = UIWindow(frame: UIScreen.main.bounds)
         self.window?.rootViewController = initialViewControlleripad
         self.window?.makeKeyAndVisible()

         return true
    }
