CancelAllLocalNotifications Not Working Sometimes

Question

Every time my app enter background, I call [[UIApplication sharedApplication] cancelAllLocalNotifications]; first.Then I reschedule localnotifications as need.

But sometimes localnotification that scheduled long time ago and should be canceled still fired.I put create time in userinfo of each localnotification. In didReceiveLocalNotification:(UILocalNotification *)notification method I get create time of this notification. And cancelAllLocalNotifications was called after that time. So I'm 100% sure this notification should be canceled.It's so wired that it still fired!

My app was tested on iOS9.0.2.Does any one has similar problem?

Use this way for remove one by one Local Notification of app. It's working, exactly as you want.

    NSArray *arrayLocalNotif = [[UIApplication sharedApplication] scheduledLocalNotifications] ;
    for (UILocalNotification *localNotification in arrayLocalNotif) {
        [[UIApplication sharedApplication] cancelLocalNotification:localNotification] ;
    }
