I have implemented remote notification in objective-c . But my problem is I want to stop alert notification .Blow my code which I am using
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
IRemoteNotificationTypeSound ];
but I still getting banner notification . and didreceiveremotenotificationmethod is successfully called
but when I change the code to
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
IRemoteNotificationTypenone ];
Then I receive no alert, no sound, and also didreceiveremotenotification not called. I want that app not show alert banner. But it must call didreceiveremotenotification in background mode, because in didreceiveremotenotification I am receiving necessary data
.

How can we pragmatically remove any pending remote notifications sent for my app from notification centre. I want to clear them up on app launch.
I have tried with [[UIApplication sharedApplication] cancelAllLocalNotifications]; API but its not helping.
PS: This question is specific to iOS 10 and old threads are not duplicates for this one.
Finally...
This one works like charm!
[[UNUserNotificationCenter currentNotificationCenter] removeAllDeliveredNotifications];
You can clear all notifications from notification centre by using these simple lines of code
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
use wherever you want. From my side I have used when user pressed logout.
You can use in
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
method to clear notifications after app opens
AFAIK, you should do it by using the background mode for remote notifications, and then responding to these notifications by issuing a local notifications.
You can remove local notifications, but not remote notifications.
Reseting the application badge number also remove all the notifications (local & remote) from the notification center.
Objective C
[UIApplication sharedApplication].applicationIconBadgeNumber = 0;
Swift
UIApplication.shared.applicationIconBadgeNumber = 0
This can definitely be achieved by using removeDeliveredNotifications(withIdentifiers:) method available in UserNotifications.framework.

I created a application. That receives push notifications from server.
This all works for me.
But the only thing is that i want that my old push notification in notification center will be removed when i receive a new one.
What do i need to do in this function
- (void)application:(UIApplication *)application didReceiveRemoteNotification: (NSDictionary *)userInfo {
This doesn't solve my problem
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
doesn't work
It is for Background(when you are home screen or locked your phone).
Or is it possible to replace your old push notification for new one
I need to clear the notification in notification center , when i click notification in notification center or badge when app in background. I can able to get log in didreceiveremoteNotification . But not clearing the notification in notification center.
you could try these two lines which i am always using when receiving a notification
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
setApplicationIconBadgeNumber is a multipurpose property to set the badge number and also clear the notifications
If I understand you correctly, you are trying to clear the badge of the push notification.
If so, use this code in
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
applicationDidBecomeActive
If a push notification is displayed to the user and the user taps it and the app is brought to the foreground from a background state then how can the app get the payload of the notification?
Because the app is already running didFinishLaunchingWithOptions: won't get called and because the app was in the background when the push arrived didReceiveRemoteNotification: won't have been called.
There are two places so I usually make a method that handles both something like this:
- (void)handleMessageFromRemoteNotification:(NSDictionary *)userInfo
Then in: application:didFinishLaunchingWithOptions:
if ([launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]) {
[self handleMessageFromRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
}
also in: application:didReceiveRemoteNotification:
[self handleMessageFromRemoteNotification:userInfo
If you want to do something different if the app is running check application.applicationState == UIApplicationStateActive in didReceiveRemoteNotification
According to Apple documentation the method didFinishLauchingWithOptions: is called when the user taps the action button of the notification.
As a result of the presented notification, the user taps the action
button of the alert or taps (or clicks) the application icon. If the
action button is tapped (on a device running iOS), the system launches
the application and the application calls its delegate’s
application:didFinishLaunchingWithOptions: method (if implemented); it
passes in the notification payload (for remote notifications) or the
local-notification object (for local notifications).
Then in this method it is easy to recover the content of the notification by doing for example :
UILocalNotification *localNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
NSString *itemName = [localNotif.userInfo objectForKey:ToDoItemKey];
[viewController displayItem:itemName]; // custom method
app.applicationIconBadgeNumber = localNotif.applicationIconBadgeNumber-1;
}
"because the app was in the background when the push arrived didReceiveRemoteNotification: won't have been called."
This, or didReceiveRemoteNotification:withExpirationHandler, should get called if the app is in the background and gets switched to the foreground when the user taps on the notification.
However I got into a situation when this wasn't working as the reason was the content of the push was incorrect, I can't remember the details but double check what's in there.
My goal is to open a specific screen when user clicks on a UILocalNotification from the iOS Notification Center.
Now if the app is being resumed from the background when user acts on the Notification, I notice didReceiveLocalNotification is called:
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
Now I can get the userInfo dictionary from the UILocalNotification object and opens the proper screen.
Unfortunately, this same method is called also when my app publishes a UILocationNotification while the app is running in the foreground:
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
How would I distinguish between the 2 cases?
It passes to you the application object that contains the state in its .applicationState property.
Consequently, you can make sure it is not active by testing...
if (application.applicationState != UIApplicationStateActive){
// do your stuff
}
And that's it!
