Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[FIXED] Facebook OSS empty AuthToken after restart game on iOS

Repro steps on iOS:

  1. Open game

  2. Login by Facebook

  3. Facebook login was successful: True

  4. AuthToken is valid

  5. Close game

  6. Open game

  7. Login by Facebook

  8. Facebook login was successful? - Already had token!

  9. AuthToken is empty!!!

FIX: In Runtime/Online/OnlineSubsystemFacebook/Private/IOS/OnlineIdentityFacebook.cpp in line 141 add following code:

 FString Token([accessToken tokenString]);
 UserAccount->AuthTicket = Token;
 GConfig->SetString(TEXT("OnlineSubsystemFacebook.Login"), TEXT("AuthToken"), *Token, GEngineIni);

Cheers! :D
