Getting facebook sdk (JSON) file in app sharing apps.
So,here is my problem,it has been around for a while which is very weird, I always get this Facebook file"com-facebook-sdk-AppEventsPersistedEvents.json" in apps such as nplayer,Documents by readdle and any other file sharing app in which I can drag and drop files from desktop.I have deleted Facebook account very long time ago and I have even checked in my iPhone that I have successfully logged out of Facebook from iPhone and I have no apps which relate to Facebook login.I have deleted this file from desktop iTunes and also from iPhone several hundreds of times from past 6-7 months but again its always there in those apps I mentioned earlier.
iPhone 6 Plus, iOS 8.2
