To get your app to show up in the first photo, your app must register for the type of files it supports. Your app's plist must contain a CFBundleDocumentTypes key and inside this array you declare the different file types that your app supports. See this Apple doc for more information: https://developer.apple.com/library/ios/documentation/filemanagement/conceptual/documentinteraction_topicsforios/Articles/RegisteringtheFileTypesYourAppSupports.html
