【问题描述】：

如果应用程序终止后从通知正文启动应用程序，我正在尝试打开弹出框。我想从AppDelegate 开始。我正在使用LocalNotifications。如果我使用操作按钮，我知道如何打开特定视图，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，我试图在代码中打开viewController，但实际上我需要警报消息，因为我正在使用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")

我尝试将其添加到else，但它没有打开特定视图：

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()

如果单击通知正文，我想要与 Twitter 或 Instagram 相同的效果，它会将您重定向到帖子。但就我而言，我只想要 popover(modal)。

【参考方案1】：

如果您的应用程序被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()

    

如果您的应用程序未处于后台模式或活动模式，您可以通过这种方式为通知设置特定的 rootview 控制器。从通知视图控制器返回后，您需要根据应用程序流程更改根视图控制器。

查看您的示例代码后，我修复了以下更改：

 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
        

    

【讨论】：

@So 如果我理解你正确我的代码现在应该可以工作了。但它不起作用。检查我的编辑。方法对吗？

在 UIApplicationLaunchOptionsRemoteNotificationKey 中是否不需要检查 application.applicationState == UIApplicationState.Active

我试过没有它，但它仍然无法工作。哦等等。我需要将我的初始 viewcotroller 设置为 "Main" 吗？因为它实际上不是初始 ATM。
