iphone: Set badge on a tabbarItem when receiving a PUSH message, when the app is inactive - iphone

I have a application that uses PUSH. But I have one problem when the application is inactive/in the background.
When the PUSH messages come and the user clicks on Close, the badge is set on the application-icon.
But I also want to set a badge on a tabBarItem.
I have this code that saves the PUSH
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
if (application.applicationState == UIApplicationStateInactive) {
//Save the PUSH until the app is active.
newPush = [userInfo copy];
}
}
And in:
- (void)applicationDidBecomeActive:(UIApplication *)application
I have the following code:
//Check if there is new PUSH messages.
if (newPush!=nil) {
//There is a new PUSH!
NSInteger badge = [[[newPush objectForKey:#"aps"] objectForKey:#"badge"] intValue];
if (badge > 0) {
//Set badge-numbers to 'badge'
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:badge];
[[[[[self tabBarController] tabBar] items] objectAtIndex:3] setBadgeValue:[NSString stringWithFormat:#"%d",badge]];
}
else {
//Set badge-numbers to zero
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
[[[[[self tabBarController] tabBar] items] objectAtIndex:3] setBadgeValue:nil];
}
}
My code for handling the PUSH when the application is active works fine and the badges are set both on the application-icon and on the tabBarItem.
Someone know what's wrong?
Thanks in advance!

If the application is inactive, didReceiveRemoteNotification is not executed. The only way the notification data can reach your app in this case is if the user taps on the notification to open the app. Then, when the app is launched, you can get the notification data in application:didFinishLaunchingWithOptions: by using this code :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions {
NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
//Accept push notification when app is not open
if (remoteNotif) {
[self handleRemoteNotification:application userInfo:remoteNotif];
return YES;
}
return YES;
}

How to create a local notification which does not show an alert but only wakes up the app to perform a calculation? [duplicate]

I would like to know, if it is possible to somehow "wake up" a task that is in the background, to quickly check something on the network.. I think that this could be done with UILocalNotification, however, no matter what I tried, I could not get the didReceiveLocalNotification to do ANYTHING when the app is in the background.. After starting up, I immediately close the app by pressing the Home button (there is a 10 second delay for local notification to fire). This code works PERFECTLY when the app is in the foreground, and just kind of sitting there...
In app delegate header file:
UILocalNotification *localNotif;
For testing, I set up local notification to fire quickly in the appDelegate startup.
localNotif = [[UILocalNotification alloc] init];
localNotif.fireDate = [NSDate dateWithTimeIntervalSinceNow:10]; // the date you want the notification to fire.
localNotif.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
NSLog(#"setup the timer for 10 seconds");
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
UIApplicationState state = [application applicationState];
NSLog(#"getting kicked");
if (state == UIApplicationStateInactive) {
// Application was in the background when notification was delivered.
NSLog(#"INACTIVE..");
} else {
NSLog(#"ACTIVE..");
}
}
The user has a couple of choices: #1) Do they want to see a notification for your app. #2) If notifications are enabled for your app, do they want to click on your notification to launch your app. If they do accept notifications and open your notification while your app is in the background, application:didReceiveLocalNotification is called. To be clear, the user has to accept the notification (such as sliding the slider underneath the notification)... otherwise NOTHING is called.
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
NSLog(#"%#", notification);
}
If your app has been terminated application:didFinishLaunchingWithOptions: is called -
- (BOOL)application:(UIApplication *)
application didFinishLaunchingWithOptions:
(NSDictionary *)launchOptions {
UILocalNotification *theNotification =
[launchOptions
objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
NSLog(#"%#", theNotification);
return YES;
}

How to clear a single notification from a list of notifications on clicking?

Once i click a notification, all the notifications are cleared.In ios, is there any option to clear a single notification after tapping on it? i have received 4 notifications. now i need the clicked notification alone to get cleared and retain the other ones.Can anyone help me on this?
- (void) clearNotifications {
[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];
[[UIApplication sharedApplication] cancelAllLocalNotifications];
}
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
NSLog(#"Received notification: %#", userInfo);
[self clearNotifications];
}
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
{
// when you tap on any of notification this delegate method will call...
[[UIApplication sharedApplication] cancelLocalNotification:notification];
}

Clearing the badge when received Push Notification

How can I clear the badge which appears on application icon when I receive Push Notification? I want to clear it once user has either tapped on "View" of Push notification alert or has tapped on the app icon.
I suspect you are talking about the SpringBoard's badge:
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]
Badge count set Zero
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0]
Cancel all local notifications with this code:
[[UIApplication sharedApplication] cancelAllLocalNotifications];
Cancel one local notification with this line of code:
[[UIApplication sharedApplication] cancelLocalNotification:theNotification];
here theNotification is a UILocalNotification object, so in order to cancel a specific notification, you need to hold on to it's UILocalNotification.
Check this.
For Mac OS X Lion, it's:
[NSApp dockTile].badgeLabel = #"";
(Lion supports badge-type push notifications.)
From Apple's documentation, set the application.applicationIconBadgeNumber to the number you want displayed on the badge. If you set it to 0, it will be cleared.
- (BOOL)application:(UIApplication *)app didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
UILocalNotification *localNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if (localNotif) {
NSString *itemName = [localNotif.userInfo objectForKey:ToDoItemKey];
[viewController displayItem:itemName]; // custom method
application.applicationIconBadgeNumber = localNotif.applicationIconBadgeNumber-1;
}
[window addSubview:viewController.view];
[window makeKeyAndVisible];
return YES;
}

Crash when handling remote notification when app not running

I receive a remote notification and according to the type of notification, change navigation controller's view controllers.
It all works fine when the app is in the foreground, or when the app is in the background but not completely closed (from multi-tasking bar).
But, when the app is closed, and receives a remote notification it crashes as soon as it opens. Am I doing wrong with the way I am setting up the ViewControllers?
Here's some code.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions {
// Push required screens into navigation controller
UILocalNotification *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
//Accept push notification when app is not open
if (remoteNotif) {
[self handleRemoteNotification:application userInfo:remoteNotif.userInfo];
return YES;
}
[window addSubview:navigationController.view];
[window makeKeyAndVisible];
return YES;
}
-(void) handleRemoteNotification:(UIApplication *)application userInfo:(NSDictionary *)userInfo {
application.applicationIconBadgeNumber = 0;
NSMutableArray *viewControllers = [NSMutableArray array];
[viewControllers addObject:driverWaitViewController];
[viewControllers addObject:newJobsViewController];
[navigationController setViewControllers:viewControllers];
}
I got this resolved, and it has nothing to do with view controllers, as I thought.
The issue was in the following lines. I was sending in remoteNotif.userInfo rather than remoteNotif itself. Also, remoteNotif is obviously not of type UILocalNotification. It is a NSDictionary object.
Before
UILocalNotification *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
[self handleRemoteNotification:application userInfo:remoteNotif.userInfo];
Should be
NSDictionary *remoteNotif = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
[self handleRemoteNotification:application userInfo:remoteNotif];
if you close the app which start from xcode debug mode, and when the app start with push notification(closed app) if the your phone connected to mac(still your phone in debug mode with xcode) it will be crash. test this senario with unplugged phone.
You aren't properly initializing your application when receiving a notification.
Change the application:didFinishLaunchingWithOptions: method to this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions (NSDictionary *)launchOptions {
// Push required screens into navigation controller
NSDictionary *notif= [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
[window addSubview:navigationController.view];
[window makeKeyAndVisible];
//Accept push notification when app is not open
if (notif) {
[self handleRemoteNotification:application userInfo:notif];
}
return YES;
}

Push notification and view button action[iphone sdk APNS]

I am developing a Push Notification enabled application for Iphone.
In My application I have two List View (UITableView)
1st for Category List and the 2nd is Contents List.
User clicks the desired category then the contents related to that category will be displayed then user will choose the contents and the contents will be displayed in detail view(generally a UIWebView).
Push notification is successfully coming in my application.
My requirement is:-
After VIEW button of Push alert is clicked application will directly display a particular
detail view (UIWebView)[Omitting category and contents list].
I have a unique ID for category and contents.
So will you please guide me how to relate a particular content with Push Notification and directly display of that content.
Thanks and regards.
HI,
I have solved the problem.
This is what I have done.
When application received push notification, it stored notification in launchOptions NSDictionary.
/* Push notification received when app is not running */
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSString *params=[[launchOptions objectForKey:#"UIApplicationLaunchOptionsRemoteNotificationKey"] objectForKey:#"contTag"];
if ([params length] > 0 ) {//app launch when VIEW button of push notification clicked
//do some processing
........
WebViewController *webViewController =
[[WebViewController alloc] initWithNibName:#"WebView" bundle:[NSBundle mainBundle]];
// Put your custom code
[[self navigationController ] pushViewController:webViewController animated:YES];
[window addSubview:navigationController.view];
/* Remote Notification Received while application was open. */
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(#"remote notification: %#",[userInfo description]);
NSString *contentsInfo = [userInfo objectForKey:#"contTag"];
NSLog(#"Received contents info : %#", contentsInfo);
NSDictionary *apsInfo = [userInfo objectForKey:#"aps"];
NSString *alert = [apsInfo objectForKey:#"alert"];
NSLog(#"Received Push Alert: %#", alert);
NSString *sound = [apsInfo objectForKey:#"sound"];
NSLog(#"Received Push Sound: %#", sound);
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
//-----------------------APNS HANDLE----------------
UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive){
NSLog(#" It is in active state");
application.applicationIconBadgeNumber = [[apsInfo objectForKey:#"badge"] integerValue];
}
else {
if ([contentsInfo length] > 0 ) {
// Do whatever u want for push notification handle
}
NOTE:
Here contTag is a key set in server side for pay load of push notification.
U can set any key in server side.
Hope it will help some body.
Thanks
