I am having the case when i am getting multiple notifications and when i select any one of them it opens up my app and does according my code.Then when i check other notifications are disappeared from the tray. Is this the usual case with notifications that opening one will remove others too or I am missing something?
I also have the question about bedge icons for multiple notifications also it is always shows 1 on the app icon. on opening of any of notification i set it to 0(zero). Does this bedge manage by server? If so how server will identify that this device is sent this many number of notifications?
As bedge are always shows 1, if i set bedge count as
int bedge = [UIApplication sharedApplication].applicationIconBadgeNumber;
bedge--;
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:bedge];
It goes to negative numbers.
you're not missing anything its usual case just because by clicking on any noti your app is getting open so all were disappear because all are related to the same application that's why once you open your app from any noti other were disappears.
About APNS:
Once your app is registered to APNS you will receive the device token. That device icon your are passing to third party server and if third party want to send the notification to the device then it will contact to APNS and ask to push the notification.
About Badges:
The badges will handled by OS. That means whenever third party pushing the notifications to the device then OS is automatically increase the count.Once you open the any notification in device notification bar or lock screen it will directly navigate to the application. Because your app ID is registered to APNS and it automatically sets the count to 0.

I am creating an app in Swift 4 and I want it to send a push notification when the wind is above a specific value. I already have the app created and when you open the app you can see the current wind (scraped from a website).
Is it possible to send a message when my phone is turned off and the app isn't running? and how to do that?
You need a server to send push notifications when your phone is turned off.
I want to reset the notification badge number whenever the app is opened. This works perfectly fine calling
application.applicationIconBadgeNumber = 0
UNUserNotificationCenter.current().removeAllDeliveredNotifications()
However, when I one ore more new notifications come in, the icon badge number again goes to 42 no matter how many notifications come in.
Does anyone know how to fix this?
You can follow one of the following for achieving this,
You can store notifications received in your database and when user opens app, you can get the count of unread notifications and update the count.
If you are targeting single users then, you can get the delivery of Push notifications using https://stackoverflow.com/a/50044201/5084797 and then when the notification is opened you can pass notification Open event to server. So the next time the server sends push notification, they can just check for the difference in Deliver and Open and send that count in badge. If user has cleared all notifications from Notification centre without opening them. In that case as soon as App opens you need to update that at server, Else you might be getting wrong count from server.
When push notification comes, it the user click the app icon instead of clicking the notification to open this app.
Then how can I get the notification payload?
As others have mentioned, you can't.
You can only get the payload when launching from Notification Center because it means the user is interested in that specific notification. If you choose to ignore the notification and open the app by pushing the icon, you won't be able to get the push payload.
They have seemingly designed the architecture in such a way as to prevent the processing of piled up push payloads (say that 10 times).
This is proven because they really only allow you to process a push payload (when the app is closed or in the background) by going through individual notifications. If this wasn't the case, they would have to allow push payload processing code to run for all apps even when they were closed or in the background state.
I have successfully created a server that sends Apple Push Notifications, and my iphone receives them.
For example I have Notification of type A and notifications of type B,
How can I control the types of notifications I received on the iphone side? For example I only want type A and not B (Just like Facebook, I want notifications for Friend Request, but not for Walls)
Thanks
you cannot stop your device on receiving a specific type of notification unless it is done on server side. Though you can ignore a notification when app is in running state as you get the notification in didReceiveRemoteNotification and you can simply ignore it after checking it but if app is in background or it is closed then you cannot control the incoming notifications from within your app.
you can make a service on server to set preferences for notification types.
from device, user can enable/disable the push service for individual features and update the preferences on server from device.
On server, before sending the PUSH, you can check for the preferences selected by user from the table and send only those notifications which the user has opted for.
I am running into a problem here. I am able to receive, capture and save an APNS message just fine if I do it while my app is running or if I click "View" when it comes in if the app is closed.
The problem I am running into is.. If the app is NOT running and I receive a APNS message and chose to look at it later by selecting "Close"... the next time I open the app, the app is not opening "with options". Therefor, the APNS message is lost. The same thing happens if the screen lock comes on before "viewing" the APNS message.
How do I handle this?
Thanks in advance!
Don’t assume that push notifications will make it to your app—their delivery isn’t guaranteed, even if the user doesn’t “close” the alert a notification brings up. Your server should have the authoritative state of whatever notifications your app needs to display when it launches, and the app should check that state regardless of whether it’s launched from a notification or not; one reason for this is that if your app receives multiple notifications while in the background, only one of those notifications will get delivered to the app when the user chooses to view it.
