swift - 如果在应用程序终止后从通知主体启动应用程序，则打开弹出窗口

Question

如果在应用程序终止后从通知正文启动应用程序，我将尝试打开弹出窗口。我想通过 AppDelegate 来完成它。我正在使用 LocalNotifications。如果我使用操作按钮，我知道如何打开特定 View ，但如果单击通知正文，我不知道如何打开某些内容。

编辑:我的解决方案仅在应用未终止时才有效。

Edit2:这样做是否正确？:

为简单起见，我尝试在代码中打开 viewController 但实际上我需要警告消息，为此我正在使用 JSSAlertView

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.



    if let TappedNotification = launchOptions?[UIApplicationLaunchOptionsLocalNotificationKey] as? NSDictionary {

        print("The notification is \(TappedNotification)")
        let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewControllerWithIdentifier("Main") as UIViewController
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        self.window?.rootViewController = initialViewControlleripad
        self.window?.makeKeyAndVisible()

    }
}





return true

我试过这个来检测应用程序处于哪个状态，但如果应用程序被终止并从通知中打开，我无法测试它:

if application.applicationState == UIApplicationState.Active {
    print("App already open")

} else {
    print("App opened from Notification")
}

我试图将它添加到 else{ 中，但它没有打开特定 View :

让 mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

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

如果点击通知正文，我想要与 Twitter 或 Instagram 相同的效果，它会重定向您进行发布。但就我而言，我只想要 popover(modal)。

如果您的应用终止并且您收到通知并点击通知，那么您可以通过以下代码获取此信息，并且您需要在 didFinishLaunchingWithOptions 方法中编写代码:

    if let TappedNotification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {

        print("The notification is \(TappedNotification)")
        let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
        let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewControllerWithIdentifier("Main") as UIViewController
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        self.window?.rootViewController = initialViewControlleripad
        self.window?.makeKeyAndVisible()

    }

如果您的应用程序不处于后台模式或事件模式，您可以通过这种方式为通知设置特定的 Root View Controller 。然后，一旦您从通知 View Controller 返回，您需要根据您的应用程序流程更改您的 Root View Controller 。

在查看您的示例代码后，我通过以下更改进行修复:

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        let tintColor = UIColor(red: 252/255, green: 72/255, blue: 49/255, alpha: 1)
        window!.tintColor = tintColor

        application.registerForRemoteNotifications()
        application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert , categories: nil))


        let notification = launchOptions?[UIApplicationLaunchOptionsLocalNotificationKey] as! UILocalNotification!
        if (notification != nil) {
                                  print("The notification is \(notification)")

                    let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
                    let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewControllerWithIdentifier("Main") as! NotificationViewController

                    self.window?.rootViewController = initialViewControlleripad
                    self.window?.makeKeyAndVisible()


                    let alert = UIAlertController(title: "Alert", message: "YES NOTIFICITO", preferredStyle: UIAlertControllerStyle.Alert)
                    alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.Default, handler: nil))
                    window!.rootViewController?.presentViewController(alert, animated: true, completion: nil)
                    return true


        }else{

            let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
            let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewControllerWithIdentifier("first") as UIViewController
            self.window?.rootViewController = initialViewControlleripad
            self.window?.makeKeyAndVisible()

            let alert = UIAlertController(title: "Alert", message: "NO NOTIFICIATION", preferredStyle: UIAlertControllerStyle.Alert)
            alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.Default, handler: nil))
            window!.rootViewController?.presentViewController(alert, animated: true, completion: nil)
             return true
        }

    }
