应用终止后删除本地通知

Question

In my app, I set up local notifications to notify the user while the app is running. In order to clean these up in case the app is terminated, I have set up applicationWillTerminate: to clear these notifications:

- (void)applicationWillTerminate:(UIApplication *)application
{
    NSLog(@"applicationWillTerminate");
    [[UIApplication sharedApplication] cancelAllLocalNotifications];
}

Unfortunately, if the app crashes, or I terminate debugging, this function isn't called and therefore I still get the local notifications delivered to the device.

Is there a way of definitely checking if the application has quit unexpectedly so I can tidy these up?

I'm using this KSCrash library with great success. Maybe it can help you also:

Or alternatively, have you set UIApplicationExitsOnSuspend on your .plist file? If you don't, there is no guarantee that applicationWillTerminate will be called, when using iOS 4.
