Question

I keep getting

\"Error Domain=com.facebook.sdk.login Code=308 \"The operation couldn’t be completed. (com.facebook.sdk.login error 308.)\"\"

Answer 1

In the FBSDKDelegate Method loginButtonWillLogin put this

- (BOOL) loginButtonWillLogin:(FBSDKLoginButton *)loginButton{
[FBSDKAccessToken setCurrentAccessToken:nil];
return YES;}
