You need to implement core data for Notifications but it can only happen when your Application is is Active state.
1-create a new identity everytime a new notification arrive.
2-save it.
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSDictionary *Notification = userInfo;
NSString *title = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:@"aps"] valueForKey:@"alert"] valueForKey:@"title"];
NSString *body = [(NSDictionary*)[(NSDictionary*)[Notification valueForKey:@"aps"] valueForKey:@"alert"] valueForKey:@"body"];
XXNotification *objNotification = [XXNotification create];
objNotification.title = title;
objNotification.detail = body;
[XXNotification save:nil];
NSArray *arrNotification =[XXNotification allUnRead:nil];
[UtilityFunctions setApplicationBadgeNumber:[arrNotification count]];//Utility functions is my class for common functions.
if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive)
{
[UtilityFunctions showAlertView:title message:body delegate:self cancelButtonTitle:@"Ok" otherButtonTitle:@"Cancel" withTag:99 withAccessibilityHint:[NSString stringWithFormat:@"%@:|:%@", title,body]];
}
else if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateInactive || [[UIApplication sharedApplication] applicationState] == UIApplicationStateBackground)
{
UILocalNotification *localNotification = [[UILocalNotification alloc] init];
localNotification.userInfo = userInfo;
localNotification.soundName = UILocalNotificationDefaultSoundName;
localNotification.alertBody = body;
localNotification.fireDate = [NSDate date];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
if (![IsLocationSaved isEqualToString:@"NO"])
{
[[NSNotificationCenter defaultCenter]postNotificationName:kNotificationForShowingNotification object: nil userInfo:nil];
}
}
}
On showing the UIAlertView, on its click event either delete that notification in DB or make a bool in it as isRead and make it YES. then save it,
On Notifications list Query the notification from DB or only those whose isRead = NO.
That is the way I did it in My Application.
