My app uses an Azure Notification Hub to send messages to both Windows Phone and iOS devices. The problem is that they work if one is called, but it doesn't work if both are called.
For example, If I send a message to an iOS device from my iOS emulator, the following code works fine and the notification appears.
var toast = PrepareMpnsToastPayload("myapp", notificationText);
var appleToast = PrepareAppleToastPayload("myapp", notificationText);
//await NotificationHelper.Instance.Hub.SendMpnsNativeNotificationAsync(toast, userTag);
await NotificationHelper.Instance.Hub.SendAppleNativeNotificationAsync(appleToast, userTag);
However, if I uncomment the SendMpns..() line, the notification never gets to the apple device. When stepping through this code with remote debugging, the call to SendMpns..() doesn't seem to return. I step over it and it just resumes.. and the breakpoint on the SendApple..() call below it never gets hit.
This works the same with the Windows Phone Mpns line (works fine without the apple call).
How am I supposed to send an alert to a user when I don't know what device they are on? I just want to send the notification to all types. Any pointers would be greatly appreciated.
EDIT: The below answers of removing await() did work. However as I now have authenticated notification hub I need to capture the return value of the call so I can see if I need to get another auth token if it has expired!
If posted code runs as trivial console application then we should wait for tasks to be completed. Easiest way to do so is removing await and calling Wait() against Task object returned by xAsync() methods:
NotificationHelper.Instance.Hub.SendMpnsNativeNotificationAsync(toast, userTag).Wait();
NotificationHelper.Instance.Hub.SendAppleNativeNotificationAsync(appleToast, userTag).Wait();

Our app has to receive silent notification from a service to work properly. Like check-in now with location info...etc.
It worked perfectly before IOS13. However it stopped working since the update. The phone receive the silent notification but IOS never wakes the app to process it if the app is in background.
I use the new headers :
request.Headers.Add("apns-id", Guid.NewGuid().ToString("D"));
request.Headers.Add("apns-push-type", "background");
request.Headers.Add("apns-priority", "5"));
request.Headers.Add("apns-topic", {BundleId});
My payload worked before however I tried the one from Apple docs as well still no luck :
{
"aps" : {
"content-available" : 1
},
"acme1" : "bar",
"acme2" : 42
}
I found on Apple forum few workarounds like send empty alert object..etc. I tried all of them still no luck.
And this all worked perfectly before IOS13!
Is anyone have any idea what is going on with the silent push notifications now on IOS13 and how to actually send one ?!
Update: maybe important info, I can send alerted notification so pushtoken..etc must be ok.
Also, when the phone connected to the Mac (not debugging, only connect trough USB) I get the silent notifications and the app waken up as before.
Found a workaround! I send a normal alerted message with the proper alert header, but add the content-available:1, then IOS13 does not show the notification, only lights the phone up for a sec, and wakes my application to process the message!
I have to send NOT the silent message format (with the "background" header)!!!, but the proper alerted message, like a normal push notification, but with content-available included!
Hello i'm newbie and im hardly to understand this notification in service-worker, and because my knowledge isn't good yet then probably i will unable to explain my problem clearly.
so here's the code :
// triggered everytime, when a push notification is received.
self.addEventListener('push', function(event) {
console.info('Event: Push');
var title = 'New commit on Github Repo: RIL';
var body = {
'body': 'Click to see the latest commit',
'tag': 'pwa',
'icon': './images/48x48.png'
};
event.waitUntil(
self.registration.showNotification(title, body)
);
});
this is the code that trigger to POP the notification, what I do not understand is where the argument to accept/ receive the data ?
I've been searched a lot: https://auth0.com/blog/introduction-to-progressive-web-apps-push-notifications-part-3/ ,
https://developers.google.com/web/updates/2015/03/push-notifications-on-the-open-web
there's some new data JSON or from git-server or push api, but I still hardly to understand where's to accept the data.
sorry if you still do not understand what's my problem.
Here to make it simple what I want :
Let's say i make a button, and everytime i click the button it will value as 'True' and I want that 'True' value to pass into argument and trigger the push of notication in service-worker.
2nd questions: am I able to trigger notification with header or text in html ? since we can manipulate the text with DOM ?
am I able to trigger notification without GCM, or API cause I just want a simple notification in serivce-worker like above without passing much data.
If you give more advice or maybe notification without service-worker but real time , I am surely happy to read it but I hope Im able to understand.
There are basically two concepts involved that work well together but can be used independently. The first is the visible UI shown to a user that tells them information or prompts them for an action. The second is sending an event from a server to the browser without requiring the user to currently be active on the site. For full details I recommend reading Google's Web Push docs.
Before either of those scenarios you have to request permission from the user. Once permission is granted you can just create a notification. No server or service worker required.
If you want to send events from a server you will need a service worker and you will need to get a subscription for the user. Once you have a subscription you would send it to a server for when you want to send an event to that specific browser instance.
Once you receive a push event from a server you display the UI the same as in the first scenario except you have to do it from the service worker.
I'm new to IOS programming, I'm trying to send message to Facebook friends using the below
[FBSDKMessageDialog showWithContent:content delegate:(id)self];
I have added callback as below:
- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results
{
NSLog(#"complete");
}
- (void)sharerDidCancel:(id<FBSDKSharing>)sharer
{
NSLog(#"Cancelled")
}
But the sharer method is not called when I send a message in FB messenger rather the sharerDidCancel is called. The sharerDidCancel method is called when user cancels or send a message, how can I differentiate send vs cancel?
Facebook has a confirmed bug concerning this, however the addressed bug there is that it always calls sharer:didCompleteWithResults instead of sharerDidCancel.
Their next release contain a fix for this (v45) and hopefully this fixes our bug too (I'm having the same problem).
In my Windows Phone 7 and 7.5 apps I used to prompt a message box when the app was launched if the user was already playing music, to notify the user to stop current music to play the sounds, or to exit the app, this was working, but when I coded from the beginning for Windows Phone 8, for some reason this code doesn't work, if you are playing a sound, instead to prompt the notification, the apps opens and close itself.
This is the code I was using:
private void Application_Launching(object sender, LaunchingEventArgs e)
{
FrameworkDispatcher.Update();
if (MediaPlayer.GameHasControl != true)
{
if (MessageBox.Show("This application requires play sounds and stop your currently playlist", "Information",
MessageBoxButton.OK) == MessageBoxResult.OK)
{
MediaPlayer.Stop();
FrameworkDispatcher.Update();
}
}
}
I'm pretty sure must be some change in the Api with the MediaPlayer? I couldn't find any information about that, someone knows how can I fix that?
Thanks!!!
As you guessed,there are some changes in APIs.
First thing I notice, calling MessageBox.Show(string) from the Application_Launching event causes an exception. You app is probably shutting down due to an unhandled exception.
From MSDN: "If you call Show(String) method from the app Activated and Launching event handlers an InvalidOperationException is thrown with the message Error Displaying MessageBox."
EDIT: The documentation on MSDN is unclear whether calling .Show(string, string, messageBoxButton) raises the same exception.

I am creating an iPhone app in which I am providing a call feature with the help of which a user can call place a call on a specified number. I am able achieve the above feature via open URL.
Now after completion of the call I want to resume the execution of app automatically. Although a user can make a fast app switch in iOS 4.0. but I want this to be done automatically.
I have seen the same behavior in "TomTom" app but I am not sure how this app has achieved it.
Thanks

Apple does not allow you to resume an app after a phone call. What you can however try doing is using a local notification.
After calling the 'call' url handler you will need to start a background task and monitor for a call state change:
CTCallCenter *c=[[CTCallCenter alloc] init];
c.callEventHandler=^(CTCall* call){
if(call.callState == CTCallStateDisconnected) {
// do stuff here
}
}
When you get a call state change, create a local notification to alert the user to resume the app. If the user taps on "view" your application will then come to the foreground. Obviously if the call is longer than 10 minutes this won't work as Apple only allows 10 minutes to background tasks.
