User Profile

I have an app that uses NotificationServiceExtension and it works great.There is a function inside this extension that calculates the distance of the notification from user and shows in the title.I want to prevent the app from showing notification based on userDefaults/any condition. Like if (distance>x) don't show the notification.if I do this, if(condition_met){show} in extension, it delivers the original push by calling serviceExtensionTimeWillExpire.Please help me on this, I want to prevent any notification if certain conditions aren't met. As we required user location here to measure distance, this can't be done on server side.
