Update badge with push notification while app in background
(12 answers)
Closed 9 years ago.
I am creating one iOS Application in which I am getting badge number from server, while the application is in foreground, I am updating the badge number in
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
}
but when the application is in background, I have no idea which function I should call.
You may send badge number in push notification like this
{"aps":{"badge":"3","alert":"help","sound":"sound.caf"}}
When the application is in the background didReceiveRemoteNotification method never calls. For doing something when your App is in background you need to implement your logic in AppDelegate's applicationDidEnterBackground: method like.
-(void)applicationDidEnterBackground:(UIApplication *)application
{
[UIApplication sharedApplication].applicationIconBadgeNumber = 2;
}
You can send the badge number from your server itself.
By default when u specify the badge number in your APN payload there is no need to set the badge number of your application. If you didn't receive the badge number from server then you cant do it anyway until the user open the application.
But in ios7 APN had a new feature.
By setting the flag Content-Available:1 will let your application run immediately after received the notification,there you can set your badge number.
Use this
- (void)applicationDidEnterBackground:(UIApplication *)application
{
[UIApplication sharedApplication].applicationIconBadgeNumber = X;
NSLog(#"Application Did Enter Background");
}
Send you badge number in the payload of push notification

iOS push notification received when app is running in foreground

How to get Push Notifications when app is opened. Get Push Notifications only when app is close or in background.
When the app is background or foreground
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(nonnull NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler
will be invoked when app is not in memory ,user interaction is needed on the push notification which opens the app and need to handle it on
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
Your question is not very clear but if you want to show notifications in notification window even when your app is active then you need to handle the same in
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)pushMessage
and post a new local notification with the same payload. which you can then handle in
- (void)application:(UIApplication *)app didReceiveLocalNotification:(UILocalNotification *)notif
Generally If the application is running in the foreground, iOS won't
show a notification banner/alert.That's by design.When app is in forground if you want to show push notification you can use UserNotification Framework for iOS 10 and it shows or displaysnotification as banner.Also you can use UILocalNotification to achieve this.Mainly we use didReceiveRemoteNotification method for achieving this.Now we have UIUserNotification methods from iOS 10.
When application is foreground and background state getting push notification
Showing Push Notification in foreground state iOS 10
I have an app and a server-side push sender. When new notifications arrive, the server sends an empty push message which only contains a badge update.
When the app is in the background, the badge is successfully updated. However, when the app is in the foreground, the badge is not updated at all - the push is delivered to the app, which discards it.
The obvious workaround is to catch the push and update the badge from within the app. For some technical reasons this would take some time to take effect (development time, app store check time, users who don't frequently upgrade etc.)
I wonder if there's a way to circumnavigate this and update the badge using a server side APNs push regardless of the app state, foreground or background.
Is there a way to change an iOS app badge using a push message, when the app is in the foreground, without handling the push notification from within the app?
This can only be achieved through application delegate methods defined in your AppDelegate
Deprecated in iOS 10
- (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo;
or,
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler;
The above delegate functions gets called when app is in foreground there you can decode your Push Payload and assign the application badge as follows
[UIApplication sharedApplication].applicationIconBadgeNumber=[[userInfo objectForKey:#"aps"] valueForKey:#"badge"];
Cheers.
I want to handle badge count increment in iOS application. On the basis of research I did so far I understand that app can read/update badge programmatically when it is in foreground. Also, ‘application:didReceiveRemoteNotification’ is called only when application is in foreground state.
However, I want to be able to increase badge even when my app is in background state. I came across the notification callback method below which gets invoked even during the background state -
application:didReceiveRemoteNotification:fetchCompletionHandler
It is introduced in iOS 7. However I noticed that even this newly introduced callback is not invoking in background state. Then after doing little more research I realised that this method calls only in case of Silent iOS notifications. So now my question is, is it possible to show badge count for silent notifications, can I receive badge count in payload ? I was just thinking of implementing the badge count calculation by leveraging the background support available for silent notifications.
Any suggestions/guidance/help is extremely invaluable for us at this moment.
Thanks.
You can put badge count in payload. In this case, the server side should handle the number of badge count. For example:
{
"aps" : {
"badge" : 5,
},
}
If your app is running foreground and to increase/decrease the badge count sent by server, this following example would help.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(#"remote notification: %#",[userInfo description]);
if (userInfo) {
NSLog(#"%#",userInfo);
if ([userInfo objectForKey:#"aps"]) {
if([[userInfo objectForKey:#"aps"] objectForKey:#"badgecount"]) {
[UIApplication sharedApplication].applicationIconBadgeNumber = [[[userInfo objectForKey:#"aps"] objectForKey: #"badgecount"] intValue];
}
}
}
}
I'm Working on PushNotification, I want to manage AppIconBadge no. in IOS.
Badge no is Receiving From parse Site, Suppose Badge no. received from parse id 20. now 20 will show on App logo when the app in background and kill State. i want it show only counting that is Remaining to read in the Notification Center. please help me how can i Manage the App Icon badge no.
App is kill state,one push notification arrived , then Which Function Called by IOS. Can i Control that Function
In kill state you can't access it. You should manage this number from parse before you send the push. to change badge number from the app itself:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: wantedNumber];
you can handle you badge count in app delegate.m didReceiveRemoteNotification method
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
alert = userInfo[#"aps"][#"alert"];
//Handle you badge count here
}
Badge number comes in payload. You need to increment the badge number at server and keep a track of badge number there itself. On receiving any notification if you open the app the badge count should be reset to any value that you can do # setApplicationIconBadgeNumber.
On app launch reset the counter to 0 or whatever you want at your server thru a network request, so that the next notification send a payload with badge number from 0.
I have the following issue: "My app receive some remote notifications from an own server just to show to the user some practical information. I am not using a icon badge, because I don't need it. If the application user touch the remote notification from the iOS Notification Center my application can catch it without any problem, I receive the options from application:didFinishLaunchingWithOptions: or, if the application is open I catch the remote notification with application:didReceiveRemoteNotification: selector. But, now I want to remove these notifications from iOS Notification Center because It is just a message and I have been looking for the answer in another posts and I've tried these solutions in my app and they don't work"
Some solutions were the next:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
[application cancelAllLocalNotifications];
application.applicationIconBadgeNumber = 0;
...
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
...
if (launchOptions) {
[application cancelAllLocalNotifications];
application.applicationIconBadgeNumber = 0;
}
...
}
And the remote notification still in the iOS Notification Center, how can I remove from that place without any tricky code or is an iOS SDK issue? I don't think that an issue was possible because Tweetbot app remove its remote notifications from iOS Notification Center after you enter to the app.
Regards!
With introduction of UNUserNotificationCenter for iOS 10 and above, it is now possible to remove few or all remote notifications of your app.
UNUserNotificationCenter documentation
With a shared singleton instance of this class, it is possible to manage delivered remote notifications on the device. Specifically, the following methods can be used:
func removeDeliveredNotifications(withIdentifiers: [String]) if you want to remove specific notification of your app, OR func removeAllDeliveredNotifications() to remove all notifications of your app.
First of all make sure you haven't set badge notification to be off in the control panel (I noticed that if the badge has a number to begin with, then badging is turned off in the control panel, it cannot be set to 0).
If its not turned off then in addition to setting applicationIconBadgeNumber to 0, also try canceling all local notifications (even if you haven't queued any, if you have first get a list of them, then cancel them, then register them back again). Yes clearing local notifications can have an effect on being able to clear the badge number for remote notifications.
