I use push notifications but while my app is closed,and push received it is not executed(i perceived by putting break point didreceived method),only appears on screen.What can i do to detect push received while app is closed?
I use also background fetch and remote notifications in target->Capabilities
MY Codes :
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^) (UIBackgroundFetchResult))completionHandler {
1) You have to set "content-available" to 1 in the notification body.
2) And have the right background modes: Background Modes
Also: Your users can turn this off by disabling Background App Refresh in the iPhone Settings. You can check this in code:
[UIApplication sharedApplication].backgroundRefreshStatus!=UIBackgroundRefreshStatusAvailable

iOS push notification received when app is running in foreground
(3 answers)
Closed 6 years ago.
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.
This method is called when a push notification is received while the app is in background mode and the user clicks on notification. But I want to call a method when notification comes in background mode without the user to click on the notification.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
NSLog(#"%#",userInfo);
}
For this to happen you need to enable Background mode for remote notifications. You can find it Capabilities section of the project. Besides that your incoming Notification Payload should contain content-available:1 key-value pair.
Then this method will be called immediately without user interaction.
Note: This works if the app is in Background or suspended state. If the app is completely killed or force quit by the user, it will not work.
There's a new feature in iOS 8: using a push notification to wake an app, which also lets the app refresh data in the background. How do I use this feature?
The push notification arrives with a value of 1 for the key 'content-available'. However, no data is received if the app is not already running in background. Why not?
There are couple of things here,
1.U need to check Remote Notification on under Background mode of the target in Capabilities section.
2.U need to implement below method,
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
I am using iOS7 and I am trying to determine if I can get the JSON payload in the following situation.
I have background mode "remote-notifications" enabled
The push notification is received while the app is terminated
The app is launched manually from the icon not from the notification center
When I launch the app from the icon itself after the notification has been received I do not get the push in the launch options from
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions;
and the following method does not get called either when app is manually launched from the icon
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
I finally figured out how you can get this!
As of iOS 7 you can get it!
Basically, you need to configure your application for background remote notifications.
So, in your info.plist file:
For required backgrounds - set it to app downloads content from push notifications.
In the AppDelegate.m file, you need to implement this method:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
See this for how to implement that: didReceiveRemoteNotification: fetchCompletionHandler: open from icon vs push notification
For your push notifications, you must have 'content-available': 1, as part of the push notification. This is what tells the application that there is new content before displaying the alert.
