We used Pushwhoosh for remote notification. Its working fine but Icon badge count not increased.
Here is code:
- (void) onPushReceived:(PushNotificationManager *)pushManager withNotification:(NSDictionary *)pushNotification onStart:(BOOL)onStart
{
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge)];
PushNotificationManager * pushManager = [PushNotificationManager pushManager];
pushManager.delegate = self;
if ([launchOptions objectForKey:UIApplicationLaunchOptionsLocationKey]) {
PushNotificationManager * pushManager = [PushNotificationManager pushManager];
[pushManager startLocationTracking];
}
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
How to increase app Icon badge count upon push delivery ?
It is a badge number issue from server side.Check whether the push notification payload contains application badge field and set to values greater than 0.
Because when the application is closed/in Background,the value in notification payloads is used to set badge in default by iOS and not the value in your code.Your code will set badge only when the application is running state.In your case,most probably the badge value passing in payload will be 0.
Got solution. We have option to set notification badge number in push whoosh server.
I have noticed that when a local notification is being received in an ios device, the notification appears in the Notification Center but the app badge number is not updated when the app is closed.
I need to touch the notification in the Notification Center for the local push message to be transferred to the app.
Is this the normal behavior? Can this be solved by using remote push notifications?
You can utilize the applicationIconBadgeNumber parameter in a UILocalNotification object.
Basically:
localNotificationObject.applicationIconBadgeNumber++;
Example:
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = [[NSDate date] dateByAddingTimeInterval:20];
localNotification.alertBody = #"Some Alert";
//the following line is important to set badge number
localNotification.applicationIconBadgeNumber++;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
But the issue with this is that the badge number doesn't increment on subsequent (multiple) local notifications (there's a scenario here but for simplicity sake, lets just say the badge stays 1 even after 2 or more, back to back, local notifications).
In this case, Yes... Push Notification seems to be the way to go
(but be aware that Push Notifications aren't always reliable... check: link)
Well... to use Push Notifications for proper badge number updates, you should know that you can send a badge count in the Push Notification's payload.
When this push notification is received, the badge count is changed by iOS to the badge count specified in the Push Notification (& the app need not be open for this).
Example (continued):
Set applicationIconBadgeNumber to 0 as it helps in certain scenarios (optional)
- (void)applicationWillResignActive:(UIApplication *)application {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
- (void)applicationWillTerminate:(UIApplication *)application {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
Extra:
You can also manually set the badge number when you terminate/close or resign the application.
Generally... in any or all of the following methods:
-applicationWillResignActive
-applicationDidEnterBackground
-applicationWillTerminate (set badgeNumber when app closes)
Example:
- (void)applicationWillResignActive:(UIApplication *)application {
//Called when the application is about to move from active to inactive state.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:[[[UIApplication sharedApplication] scheduledLocalNotifications] count]];
//...
}
- (void)applicationWillTerminate:(UIApplication *)application {
// Called when the application is about to terminate.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:[[[UIApplication sharedApplication] scheduledLocalNotifications] count]];
//...
}
iPhone: Incrementing the application badge through a local notification
It is not possible to update dynamically the badge number with local notifications while your app is in the background. so You have to use push notifications. You can only increment badge while application is running in foreground and look for alternative solution you can go with here
iPhone: Incrementing the application badge through a local notification
[[UIApplication sharedApplication] cancelAllLocalNotifications];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];'
I added the above code to didfinishLaunchingWithOptions but when a user taps a notification in his notification center and enters my app the notification does not gets cleared.
Edit:
I also tried adding this to my code:
You Also need to increment then decrement the badge in your
application:didReceiveRemoteNotification: method if you are trying
to clear the message from the message centre so that when a user
enters you app from pressing a notification the message centre will
also clear, ie:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
as describes here: iOS application: how to clear notifications? but the notification still won't clear from the notification center
I just Added a Badge number manually to my application and pasted
- (void)applicationDidBecomeActive:(UIApplication *)application
{
application.applicationIconBadgeNumber = 0;
}
To my AppDelegate. For me this works like a charm.
Note that didfinishLaunchingWithOptions and applicationDidBecomeActive are not the same as Mouhammad Lamaa explained. If you paste this to your AppDelegate and tap the notification in notification center it should disapper. If it does not your App maybe creates a new Notification after becoming active?
add this code
- (void)applicationDidBecomeActive:(UIApplication *)application
{
application.applicationIconBadgeNumber = 0;
}
the didfinishlaunchingwithoptions launched at the initial launch of your app. if your app the running in the background, didfinishlaunchingwithoptions will not be launched.
When the user open application from notification action - it launches with
- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *remoteNotif =
[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (remoteNotif) {
//handle remote notification
}
....
}
But when the app was in background it calls
- application:didReceiveRemoteNotification:
Also method [[UIApplication sharedApplication] cancelAllLocalNotifications]; cancel registered LOCAL notifications only. Push notifications can't be canceled - they delivered immediately and executed only once.
I've an iOS application where some Push Notification are sent to. My problem is, that the messages/notifications stays in the Notification Center in iOS after then are tapped. How can I remove a notification for my application in the Notification Center next time the application opens?
I came across posts where people are calling setApplicationIconBadgeNumber to a zero-value to clear the notifications. That's seems very weird to me, so I believe that maybe another solution exists?
EDIT1:
I'm having some problems clearing the notifications. Please see my code here:
- (void) clearNotifications {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (launchOptions != nil)
{
NSDictionary* dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (dictionary != nil)
{
NSLog(#"Launched from push notification: %#", dictionary);
[self clearNotifications];
}
}
return YES;
}
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
NSLog(#"Received notification: %#", userInfo);
[self clearNotifications];
}
I'm running the App through Xcode. When the App is minimized and I start the App using the notification in the Notification Center, I can see in the log, that the didReceiveRemoteNotification is called and using breakpoints I can see, that the clearNotifications has ran. But still the notification hangs in the Notification Center. Why?
Most likely because Notification Center is a relatively new feature, Apple didn't necessarily want to push a whole new paradigm for clearing notifications. So instead, they multi-purposed [[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0]; to clear said notifications. It might seem a bit weird, and Apple might provide a more intuitive way to do this in the future, but for the time being it's the official way.
Myself, I use this snippet:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
which never fails to clear all of the app's notifications from Notification Center.
Just to expand on pcperini's answer. As he mentions you will need to add the following code to your application:didFinishLaunchingWithOptions: method;
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
You Also need to increment then decrement the badge in your application:didReceiveRemoteNotification: method if you are trying to clear the message from the message centre so that when a user enters you app from pressing a notification the message centre will also clear, ie;
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
It might also make sense to add a call to clearNotifications in applicationDidBecomeActive so that in case the application is in the background and comes back it will also clear the notifications.
- (void)applicationDidBecomeActive:(UIApplication *)application
{
[self clearNotifications];
}
Update for iOS 10 (Swift 3)
In order to clear all local notifications in iOS 10 apps, you should use the following code:
import UserNotifications
...
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.removeAllPendingNotificationRequests() // To remove all pending notifications which are not delivered yet but scheduled.
center.removeAllDeliveredNotifications() // To remove all delivered notifications
} else {
UIApplication.shared.cancelAllLocalNotifications()
}
This code handles the clearing of local notifications for iOS 10.x and all preceding versions of iOS. You will need to import UserNotifications for the iOS 10.x code.
If you have pending scheduled local notifications and don't want to use cancelAllLocalNotifications to clear old ones in Notification Center, you can also do the following:
[UIApplication sharedApplication].scheduledLocalNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;
It appears that if you set the scheduledLocalNotifications it clears the old ones in Notification Center, and by setting it to itself, you retain the pending local notifications.
If you're coming here wondering the opposite (as I was), this post may be for you.
I couldn't figure out why my notifications were clearing when I cleared the badge...I manually increment the badge and then want to clear it when the user enters the app. That's no reason to clear out the notification center, though; they may still want to see or act on those notifications.
Negative 1 does the trick, luckily:
[UIApplication sharedApplication].applicationIconBadgeNumber = -1;
In Swift I'm using the following code inside my AppDelegate:
func applicationDidBecomeActive(application: UIApplication) {
application.applicationIconBadgeNumber = 0
application.cancelAllLocalNotifications()
}
Maybe in case there are scheduled alarms and uncleared app icon badges.
NSArray *scheduledLocalNotifications = [application scheduledLocalNotifications];
NSInteger applicationIconBadgeNumber = [application applicationIconBadgeNumber];
[application cancelAllLocalNotifications];
[application setApplicationIconBadgeNumber:0];
for (UILocalNotification* scheduledLocalNotification in scheduledLocalNotifications) {
[application scheduleLocalNotification:scheduledLocalNotification];
}
[application setApplicationIconBadgeNumber:applicationIconBadgeNumber];
When you have repeated notifications at future, you do not want to cancel those notifications, you can clear the item in notification center by:
func clearNotificationCenter() {
UIApplication.sharedApplication().applicationIconBadgeNumber = 1
UIApplication.sharedApplication().applicationIconBadgeNumber = 0
}
You cannot clear notification when your app is open in the foreground by calling the method below immediately after receiving local notification, otherwise you will receive tens of hundreds of notifications. Maybe because the same notification apply again, and now is the time to fire, so you keep fire, apply again, fire, apply....:
[UIApplication sharedApplication].scheduledLocalNotifications = [UIApplication sharedApplication].scheduledLocalNotifications;
When you logout from your app, at that time you have to use a below line of code on your logout button click method.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
and this works perfectly in my app.
You need to add below code in your AppDelegate applicationDidBecomeActive method.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
Got it from here. It works for iOS 9
UIApplication *app = [UIApplication sharedApplication];
NSArray *eventArray = [app scheduledLocalNotifications];
for (int i=0; i<[eventArray count]; i++)
{
UILocalNotification* oneEvent = [eventArray objectAtIndex:i];
//Cancelling local notification
[app cancelLocalNotification:oneEvent];
}
Is there any way to handle the push notification from the Notification Center after being tap, and remove it when my application has already launched?
I know this is hack and slash, but you can clear all notifications by changing the badge number on your application.
- (void)application:(UIApplication*)application didReceiveRemoteNotification (NSDictionary*)payload
{
NSLog(#"Received notification: %#", payload);
//swapping between two badge numbers to clear notifications
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
...
}
If you already had a badge number you don't want to lose (above example will simply clear badge number in the end) you can do something like
- (void)application:(UIApplication*)application didReceiveRemoteNotification (NSDictionary*)payload
{
NSLog(#"Received notification: %#", payload);
/*
storing current badge number then swapping between 2 values to make sure we
clear the badge number. Once this is done set badge number back to original
value.
*/
int badgeNum = [[UIApplication sharedApplication] applicationIconBadgeNumber]
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:1];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badgeNum];
...
}
This may not be best practice, but it gets the job done and the client will not know the difference. I like to call it a temp. fix until I stumble upon a better solution. Hope this helps someone!
