OneSignal Not calling didReceiveRemoteNotification

问题:

We migrated from UA to One Signal. We are sending push from cloud code like

var pushInfo = {
      "app_id" : "xxxxxx",          
      "data": {
          "objectId": objectId,
          "placeId": placeId,
      },
      "included_segments": ["All Users"],
      "contents": {"en": message}
};
var headers = {
    "Content-Type": "application/json; charset=utf-8",
    "Authorization": "Basic XXXXX"
};

var options = {
 host: "onesignal.com",
 port: 443,
 path: "/api/v1/notifications",
 method: "POST",
 headers: headers,
};

var https = require('https');
var req = https.request(options, function(res) {  
res.on('data', function(data) {
  console.log("Response:");
  console.log(JSON.parse(data));
});
});

req.on('error', function(e) {
console.log("ERROR:");
console.log(e);
 });  
req.write(JSON.stringify(pushInfo));
req.end();

In my AppDelegate.m I do

[OneSignal initWithLaunchOptions:launchOptions appId:@"XXXXX"];

Now earlier when a notification is received and user Taps on it, it used to call

-(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler

Q. This is not getting called now. How do I handle it with OneSignal. Q. What I need to do to handle a silent notification (no visible badge/banner etc)

回答1:

I Assume you are testing/running your app on an iOS10 device,

I looked at OneSignal SDK Code and I think the SDK automatically uses the new UserNotifications Framework (add in iOS10), when iOS10 is detected on device.

In this case, the AppDelegate method you mentioned above does not get invoked, instead methods in UNUserNotificationCenterDelegate get invoked, which are captured by SDK to record clicks/views.

To Fix the issue, Create a new class which implements OSUserNotificationCenterDelegate and provide its instance to OneSignal using [OneSignal setNotificationCenterDelegate:yourCustomNotificationCenterDelegateInstance]

Please note that application:didReceiveRemoteNotification:fetchCompletionHandler: is still called when a silent push notification (content-available: 1) arrives, but its not called when user taps the notification if UNUserNotificationCenterDelegate is used.

Also, there was an issue on iOS 10.0.X where the application:didReceiveRemoteNotification was called instead of application:didReceiveRemoteNotification:fetchCompletionHandler: See: https://forums.developer.apple.com/thread/54332 , but I doubt if this is the case with you.

One Signal Notification Integration

Use Following Block Of Code TO Handle PushNotification Message Content

Put below code in AppDelegate's ApplicationDidFinishLaunch Options method

    let notificationReceivedBlock: OSHandleNotificationReceivedBlock = { notification in

        print("Received Notification: \(notification!.payload.notificationID)")
    }

    let notificationOpenedBlock: OSHandleNotificationActionBlock = { result in
        // This block gets called when the user reacts to a notification received
        let payload: OSNotificationPayload = result!.notification.payload

        var fullMessage = payload.body
        print("Message = \(String(describing: fullMessage))")

        if payload.additionalData != nil {
            if payload.title != nil {
                let messageTitle = payload.title
                print("payload.category \(payload.category)")
                print("payload.subtitle \(payload.subtitle)")
                print("Message Title = \(messageTitle!)")
            }

            let additionalData = payload.additionalData
            if additionalData?["actionSelected"] != nil {
                fullMessage = fullMessage! + "\nPressed ButtonID: \(String(describing: additionalData!["actionSelected"]))"
            }
        }
    }

    let onesignalInitSettings = [kOSSettingsKeyAutoPrompt: false,
                                 kOSSettingsKeyInAppLaunchURL: true]

    OneSignal.initWithLaunchOptions(launchOptions,
                                    appId: "Your App Id",
                                    handleNotificationReceived: notificationReceivedBlock,
                                    handleNotificationAction: notificationOpenedBlock,
                                    settings: onesignalInitSettings)
   **Use following block of code To Receive OneSingnal Notification Content** 

    OneSignal.inFocusDisplayType = OSNotificationDisplayType.notification;

    // Recommend moving the below line to prompt for push after informing the user about
    //   how your app will use them.
    OneSignal.promptForPushNotifications(userResponse: { accepted in
        print("User accepted notifications: \(accepted)")
    })

application:didReceiveRemoteNotification:fetchCompletionHandler: is the correct selector for background silent content-available notifications. Make sure you are using the latest 2.2.2 OneSignal SDK as there were some fixes to maintain compatibility with the older AppDelegate selectors.

You may want to look into using UNNotificationServiceExtension with mutable-content for iOS 10 devices as this still works when the app has been swiped away.
