Just like what the title says, is this a bug or is it really possible? I use the [FBSDKAccessToken currentAccessToken].tokenString
to check whether an existing Facebook session is existing, then afterwards I'll use the [FBSDKProfile currentProfile].userID
to get the session's userId. However sometimes I encounter that [FBSDKAccessToken currentAccessToken].tokenString
has a value but [FBSDKProfile currentProfile]
is nil.
I use this for the auto-login feature of my application.
Thanks for your response!
So I have this code snippet:
if ([FBSDKAccessToken currentAccessToken].tokenString){
//proceed to auto login since Facebook is still logged in
NSLog(@"Facebook user id: %@",[FBSDKProfile currentProfile].userID)
}
The return of that log is nil.
if ([FBSDKAccessToken currentAccessToken].tokenString) {
[FBSDKProfile enableUpdatesOnAccessTokenChange:YES];
NSLog(@"Facebook user id: %@",[FBSDKProfile currentProfile].userID);
}
you need to call [FBSDKProfile enableUpdatesOnAccessTokenChange:YES]
so that it automatically observes changes to the [FBSDKAccessToken currentAccessToken]
