当iOS应用程序被挂起/终止且用户单击通知时，如何处理Firebase推送通知？

我想知道当我的应用程序被挂起/终止时，应该回调什么函数，或者何时收到通知。当我的应用程序处于前台/后台时，我可以处理，但是当应用程序被终止时，我不确定如何以及在哪里处理或解析我的通知负载？

在通知打开的应用程序上，您将在应用程序中获得通知数据：将调用didFinishedLaunchingWithOptions方法

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if (launchOptions != nil)
    {
        // opened from a push notification when the app is closed
        NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        if (userInfo != nil)
        {
             NSLog(@"userInfo->%@", [userInfo objectForKey:@"aps"]);
        }
    }
    else
    {
        // opened app without a push notification.
    }
}

Swift 5.1

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
    if launchOptions != nil {
        // opened from a push notification when the app is closed
        let userInfo = launchOptions?[.remoteNotification] as? [AnyHashable : Any]
        if userInfo != nil {
            if let object = userInfo?["aps"] {
                print("userInfo->\(object)")
            }
        }
    } else {
        // opened app without a push notification.
    }
}

用Swift怎么样？现在我需要从appdelegate演示和演示一个Viewcontroller。如何实现这一点？您可以使用ApplicationLegate.window.rootviewcontroller演示viewcontroller
