I have this problem now, I need to handle the info of push notification when app in backround, I mean, even not tap the notifcation.
That mean this application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler must be called in background !
Here is my code for it
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
NSLog(#"full message %#", userInfo);
NSDictionary *aps = [userInfo objectForKey:#"aps"];
NSLog(#"full aps %#", aps);
NSString *custom = [userInfo objectForKey:#"custom"];
NSLog(#"full custom %#",custom);
completionHandler(UIBackgroundFetchResultNewData);
[[NSNotificationCenter defaultCenter] postNotificationName:#"notificationRemote" object:nil userInfo:userInfo];
}
I really need handle the info, such that save it to local everytime I have any notification, no matter I tap in push notification.
I search and I saw that I need content-available for my payload, but I can't find it in Firebase Console Notification.
Yup, you need content-available key in payload for silent push notification.
for more about FCM, U can see this link:
Firebase silent apns notification
You can use FireBase Cloud Function to create a payload and Fire a Notification.You can handle events in the Firebase Realtime Database.
The Realtime Database supports the onWrite() event, which triggers anytime data is created, destroyed, or changed in a specified database location.
Please refer this tutorial for detail which may help you

How to insert the push notification payload data into database when app is in background. I tried the content-available tag but it doesn't work for me.
Please help me out
content-available tag also required and use this method:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
//add notification data to your database here
completionHandler(UIBackgroundFetchResultNewData);
}
And add this to your xcode.
I have setup silent push notification and all works fine when app is in foreground or in background.
The problem is when the application is not active/killed (if i have understand well, any application is killed automatically after 30 seconds when it is in background).
My payload is like this
{"aps":{"alert":"test","sound":"bingbong.aiff","badge":33,"content-available":1}}
All works fine but when i receive this push, badge icon is not update (no 33 is appear near the application icon). This is the first problem.
The second problem is that i dont know how to get the notification when the app is killed.
My idea was to call the service if the badge icon was great than 1, in this way i know that there are some notification to download and i can contact the server to get them.
A silent push notification doesn't need the alert, either the sound to be specified, since it's not presented to the user.
The silent notification you will get through application:didReceiveRemoteNotification:fetchCompletionHandler::
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
//load the new available content and call the completionhandler.
}
The badge should be displayed if the app has the correct permissions. You can register your app to display the badge like this:
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge];
Anyway you don't have to check the badge number to download new content. You can simply attach your own key-value-pairs to the notification:
{
"aps": {
"badge": 33,
"content-available":1
},
"load-data": 1,
"load-data-id": 12
}
When you receive the notification in the app just check for your param in the userInfo dictionary:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
int loadData = [[userInfo objectForKey:#"load-data"] intValue];
int loadDataId = [[userInfo objectForKey:#"load-data-id"] intValue];
}
All of this is documented in the Local and Push Notification Programming Guide in the iOS documentation.
Hi I am developing small IOS application in which I am using push notification. So in my case I am able get notifications and I am also able to access data for notification. Data from notification mean title, description etc. So in my case I am not saving my notification at my server side. I want to save those locally. For that what I want as soon as notification come I want to save that data locally. I am able to access my data when App is in foreground but I am not able to access my notification data when app is in background. I want to access the data of notification so that I can save it. For notification I did following things:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[application registerForRemoteNotificationTypes:
UIRemoteNotificationTypeBadge |
UIRemoteNotificationTypeAlert |
UIRemoteNotificationTypeSound];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
return YES;
}
- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken {
}
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo {
for (NSString *key in [userInfo allKeys])
{
NSString *data = [userInfo objectForKey:key];
NSLog(#"inside did register for notification .... %# ---- > %#",key,data);
}
}
My requirement is simple I want access to notification when my app is in background. Any one is here who already did this? Need Help. Thank you.
In iOS, the app cannot access it's push notification until the user taps on the push notification from the notification center.
Once the push notification is tapped and the app loads/becomes active, only then will you be able to access the push notification.
FYI:
When the app is in background and a push notification is recieved.
After the user taps on the push notification:
the contents will be accessible in the -didReceiveRemoteNotification: method.
When the app is not open and a push notification is received.
After the user taps on the push notification
the contents will be accessible in the -didFinishLaunchingWithOptions: method in it's launchOptions parameter.
Also... push notifications aren't 100% reliable. They may or may not be delivered (although them not being delivered is pretty rare in my observation but worth pointing out none-the-less)
There is a way in iOS 7.0 and later where you can send notifications and access its content without user tapping it.
So, the notification payload which you send has a parameter called content-available. You can view the payload parmeters in the following link:
https://developer.apple.com/library/ios/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/ApplePushService.html
So when you set the content available to 1 and deliver the notification, iOS calls the below function even if the app is not in the background or foreground(must have remote notification enabled)
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))handler
Then you can use the userInfo dictionary to fetch your notification data.
By default, when a push (remote) notification is received, is a NSNotification posted to the default NSNotification center?
I know that - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo is called, but I'd like another class to know that a push notification was received.
Do I have to post a NSNotification by myself or is it automatically posted?
I am trying to develop an iOS app using UrbanAirship. I receive push
notifications but cannot get any delegate to be called when the app is in
the background. I (wrongfully it seems) assumed that the
handleBackgroundNotification API from the UAPushNotificationDelegate
class would provide me the functionality to execute custom actions when
receiving the notification when app is in the background.
This is what their documentation says:
"handleBackgroundNotification:
Called when a push notification is received when the application is in the background
- (void)handleBackgroundNotification:(NSDictionary *)notification
Parameters
notification
the push notification
"
- see https://docs.urbanairship.com/ios-lib/Classes/UAPushNotificationHandler.html#//api/name/handleBackgroundNotification:
Doesn't seem to work that way - sure seems the OS is keeping the notification
for itself - which is inline with Apple's documentation.
I am questioning the purpose of the function if the OS doesn't allow it. I use didReceiveRemoteNotification for receiving remote push notifications which works just fine!
However, since this is an enterprise application (i.e. not App Store),
if there are private APÏs and frameworks that would allow me to do this,
I would appreciate any assistance. There is no way this app would ever
make it to the app store!
The custom actions I am trying to execute include, for example, a
notification receipt sent to a server that would "prove" the recipient
app did indeed receive the notification, play a custom sound at maximum
volume (bypassing silence and do not disturb mode). These are some
requirements from the client.
This is what I use and its working just fine:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if(!loggedIn) return;
NSLog(#"WOW: got notification! %#", userInfo);
// see this for fine tuning: http://fivelakesstudio.blogspot.com/2012/04/push-notifications-and-urban-airship.html
[[UAPush shared] handleNotification:userInfo applicationState:application.applicationState];
[[UAPush shared] resetBadge];
sharedApplication.applicationIconBadgeNumber = 0; // probably redundant
[self handlePushNotification:userInfo isBooting:NO]; // my common handler
}
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
UA_LINFO(#"Application received remote notification: %#", userInfo);
[[UAPush shared] appReceivedRemoteNotification:userInfo applicationState:application.applicationState fetchCompletionHandler:completionHandler];
NSDictionary *values = [userInfo objectForKey:#"aps"];
NSString *title = [values objectForKey:#"alert"];
}
process the notification received for all states in this block.
NB. you can monitor the application.applicationState value to note the state of the app when the notification is received.
Hope this helps
