在远程推送通知上重定向以更正 ViewController

Question

我正在努力让我的 iOS 应用程序在通过远程推送通知（使用 Swift）打开时按预期运行。我想要的是，当通过点击推送通知打开应用程序时，它应该直接跳转到某个 ViewController，但仍保持导航堆栈。更复杂的是，目标视图控制器取决于推送消息。

示例：我的应用已关闭，我收到推送通知："You got a new message"。我单击通知，应用程序打开并显示新消息，而不是常规的初始视图控制器。如果我的应用程序打开并且我收到推送通知，则什么也不会发生。

一般来说，这里是响应通知的方法。通过这些方法，您需要实现代码以根据通知向您的堆栈显示适当的视图。

要在应用运行在前台或后台运行时响应通知，请实施 application:didReceiveRemoteNotification:fetchCompletionHandler: 方法。如果您启用了远程通知后台模式，系统会启动您的应用程序（或将其从挂起状态唤醒）并在远程通知到达时将其置于后台状态。但是，如果用户强行退出，系统不会自动启动您的应用程序。

要在您的应用运行在前台而非后台时响应通知，请实施 application:didReceiveRemoteNotification: 方法

要在您的应用不是运行时响应通知，请实施 application:willFinishLaunchingWithOptions: 或 application:didFinishLaunchingWithOptions: 方法

所以我最后做的是：

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
        if application.applicationState == .Inactive || application.applicationState == .Background {
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            let navigationController = self.window?.rootViewController as? UINavigationController
            let destinationController = storyboard.instantiateViewControllerWithIdentifier("dashboard") as? DashboardViewController
            navigationController?.pushViewController(destinationController!, animated: false)
            let destinationController2 = storyboard.instantiateViewControllerWithIdentifier("notificationsSettings") as? AppSettingsTableViewController
            navigationController?.pushViewController(destinationController2!, animated: false)
        }
    }

所以在 didReceiveRemoteNotification 中，我检查应用程序来自哪个状态，然后导航到我想呈现给用户的 viewController。我不直接转到 ViewController 的原因是因为我希望导航堆栈是 "intact" 以便用户可以通过 navigationController 导航回来。

我在 Objective C 中做了同样的事情，基于 @NikMos 回答

// Handle notification messages after display notification is tapped by the user.
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
#if defined(__IPHONE_11_0)
         withCompletionHandler:(void(^)(void))completionHandler {
#else
withCompletionHandler:(void(^)())completionHandler {
#endif


    if (([UIApplication sharedApplication].applicationState == UIApplicationStateBackground) ||
        ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive)) {
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
        UINavigationController *navigationController=[[UINavigationController alloc] init];
        self.window.rootViewController =nil;
        self.window.rootViewController = navigationController;
        ScannerViewController *scannerVc = [storyboard instantiateViewControllerWithIdentifier:@"ScannerID"];
        [navigationController pushViewController:scannerVc animated:YES];
        NotificationVC * notificationVC  = [storyboard instantiateViewControllerWithIdentifier:@"NotificationVCID"];

        [navigationController presentViewController:notificationVC animated:YES completion:nil];

         [self.window makeKeyAndVisible];
}

编码并享受编码。干杯 :)
