ios - 推送通知不会快速调用 didReceiveRemoteNotification

Question

我已经使用 FCM 实现了推送通知。当我的应用程序位于前台并且通知到达时，将调用 didReceiveRemoteNotification 方法，但当应用程序未处于事件状态时，它不会调用此方法

当应用程序在后台时，我通过将 bool 值设置为 true 来检查这一点，但不更改 bool 值，这意味着它不会执行此行。这是我的方法。

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
        self.application(application, didReceiveRemoteNotification: userInfo) { (UIBackgroundFetchResult) in
            if UIApplication.sharedApplication().applicationState != .Active{


            NSUserDefaults.standardUserDefaults().setBool(true, forKey: "AriveNotification")
            NSUserDefaults.standardUserDefaults().synchronize()
            }else{

                NSUserDefaults.standardUserDefaults().setBool(false, forKey: "AriveNotification")
                NSUserDefaults.standardUserDefaults().synchronize()
            }
        }
    }


    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
        if UIApplication.sharedApplication().applicationState != .Active{


            NSUserDefaults.standardUserDefaults().setBool(true, forKey: "AriveNotification")
            NSUserDefaults.standardUserDefaults().synchronize()
            }else{

                NSUserDefaults.standardUserDefaults().setBool(false, forKey: "AriveNotification")
                NSUserDefaults.standardUserDefaults().synchronize()
            }
        }
        completionHandler(.NewData)
    }

为了注册 GCM 推送通知，我在用户成功登录时使用这些方法。

func userDidLoggedIn() -> Void {
    tabBarController = storyboard.instantiateViewControllerWithIdentifier("TabBarController") as! VaboTabBarController


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

    self.registerDeviceForPushNotification(UIApplication.sharedApplication())

}
func connectToFcm() {

    FIRMessaging.messaging().connectWithCompletion({error in


        if (error != nil) {
            print("Unable to connect with FCM. \(error)")
        } else {
            print("Connected to FCM.")
        }


    })
}
func application(application: UIApplication,
                 didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
}


func registerDeviceForPushNotification(application:UIApplication) -> Void {

    let settings: UIUserNotificationSettings = UIUserNotificationSettings.init(forTypes: [.Alert,.Badge,.Sound], categories: nil)
    self.pushNotificationToken = FIRInstanceID.instanceID().token()!
    let userID = self.userData["id"] as! NSNumber

    print("InstanceID token: \(self.pushNotificationToken)")
    self.registerDeviceOnServerWith(self.pushNotificationToken, userID: userID)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()
}


func tokenRefreshNotification(notification: NSNotification) {
    if let refreshedToken = FIRInstanceID.instanceID().token() {

        let userID = self.userData["id"] as! NSNumber

        self.registerDeviceOnServerWith(refreshedToken, userID: userID)
        print("InstanceID token: \(refreshedToken)")
    }

    // Connect to FCM since connection may have failed when attempted before having a token.
    connectToFcm()
}

PS。我已经从功能以及 info.plist 中设置了远程通知检查。另外，我还尝试从通知负载中添加 "content-available":1 。

Answer 1

您必须在通知负载中写入正确的拼写和字符位置。根据您的陈述，您可能在内容可用的位置放置了不正确的字符。请以此格式发送您的有效负载..

{
    "aps":{
        "alert":{
            "title":"Notification Title Text",
            "Body" :"Notification Body",
            "content_available":1

        }
    }
}

您已经编写了content-available，它应该是content_availble。现在这将唤醒您的应用程序以在后台运行您的逻辑
