iOS Parse Facebook Login error 308 FBSDKLoginBadChallengeString

Question

I\'m trying to implement Facebook login in my iOS app, using Parse.

let permissionsArray = [\"public_profile\", \"email\"]

PFFacebookUtils.logInInBackgroun         


        

Answer 1

I'm using

pod 'FBSDKCoreKit', '~> 4.8.0'
pod 'FBSDKLoginKit', '~> 4.8.0'
pod 'FBSDKShareKit', '~> 4.8.0'

... and had the code 308 problem when I logged out and logged in during the same session. Using [[FBSDKLoginManager alloc] logOut] or [facebookLoginManager logOut] (with a persisted manager) just before calling logInWithReadPermissions: didn't work, but adding

[FBSDKAccessToken setCurrentAccessToken:nil];
[FBSDKProfile setCurrentProfile:nil];

before the logInWithReadPermissions: call works ok. (Tested in iOS 9.2.)
