didReceiveLocalNotification triggered when presentLocalNotificationNow is called

Question

When I create my local notification callback didReceiveLocalNotificationgets triggered. The same callback gets triggered when I click on the local notification. Currently I was dividing those two cases by checking

if ([UIApplication sharedApplication].applicationState == UIApplicationStateInactive) {
    //this means notification is clicked
}

But the main problem here is that when you are in the foreground and you slide your notification menu, and then receive your local notification, this callback didReceiveLocalNotification gets called. And in this case my app goes into this if. Because of this, I can't really distinguish from clicking the notification and creating a local notification while app is in the inactive state. Any ideas on how can I fix this?

This is the code for scheduling a local notification:

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.alertBody = @"aaaa";
localNotification.alertTitle = @"title";
localNotification.userInfo = myUserInfo;
[[UIApplication sharedApplication] presentLocalNotificationNow:localNotification];

After calling this, I get didReceiveLocalNotification delegate triggered.

I had to work around the exact same issue in my app. I couldn't find an offical way in the API to tell the difference, but here is a workaround.

Pass the current date in the userInfo when the local notification is created:

localNotification.userInfo = ["alertDate": NSDate()]

And when you handle didReceiveLocalNotification, check against current date again, to make sure it didn't just fire just a moment ago:

if application.applicationState == .Inactive {
    if let alertDate = notification.userInfo?["alertDate"] as? NSDate 
        where (NSDate()).timeIntervalSinceDate(alertDate) > 0.1 {
        // this means notification was initiated by user
    }
}
