ReAuthorize Facebook App in Parse ios SDK

Question

I logged into my app using my FB credentials via the standard Parse SDK instructions. All worked fine, until I was playing with the phone settings and decided to switch off the application's fb authorization in the privacy settings in my phone.

I then couldn't log into the app using my FB credentials anymore. So I tried to remove the app from my facebook apps via facebook.com and waited a while, but still I get error:

com.facebook.sdk:ParsedJSONResponseKey={ body = { error = { code = 190; "error_subcode" = 458; message = "Error validating access token: The user has not authorized application xxxxxx."; type = OAuthException; }; }; code = 400; headers = ( { name = "Access-Control-Allow-Origin"; value = "*"; }, { name = "Content-Type"; value = "text/javascript; charset=UTF-8"; }, { name = Pragma; value = "no-cache"; }, { name = Vary; value = "Accept-Encoding"; }, { name = "Cache-Control"; value = "no-store"; }, { name = "WWW-Authenticate"; value = "OAuth \\"Facebook Platform\\" \\"invalid_token\\" \\"Error validating access token: The user has not authorized application xxxxxxxxx.\\""; }, { name = Expires; value = "Sat, 01 Jan 2000 00:00:00 GMT"; } ); }}

Answer 1

I ended up solving the issue on my phone by resetting my privacy settings. Its an issue with iOS for not flushing the privacy settings once a user de-authorizes the application. It should have just asked for permission but the didn't.
