Apple Game Center Login

[torch-ray]

1.03 버전 기준 버그 발생 -> 1.04에서 수정 필요

• Apple Game Center 오류 일부 유저에게서 발생 ( 정상 동작되는 유저도 있고 오류 발생하는 유저도 있음)
• 네트워크 미연결 상태에서는 게임센터 로그인이 정상 진행
• 네트워크 연결 상태에서는 게임센터 로그인이 진행되지 않음
• 미연결상태에서 로그인 후, 네트워크를 연결해도 로그아웃 처리됨( 로그아웃 되었다는 메시지가 나오는 건 아니고, rank Scene에 들어가보면 네트워크 미연결 시에는 점수만 안뜨는데, 네트워크 연결하고 다시 들어가보면 게임센터 로그인되어있지 않다고 메시지 나옴)

if GKLocalPlayer.local.isAuthenticated {
  //네트워크 연결과 관계없이 계속 true값을 리턴하고 있음
}

여기값이 true일 때는 gcViewController는 항상 nil을 반환

[torch-ray]

else if let error = error { 
  // User가 Apple Game Center 로그인 3회 이상 취소했을 때 발생하는 Error
 // GKLocalPlayer.local.authenticateHandler = { [unowned self] _, error in 여기에서의 Error임
}

[torch-ray]

GameCenterAuthProvider.getCredential { credential, error in 
  // 여기 에러는 credential을 못가져오면 발생하는 에러인 것 같음
  // 에러발생할 때 credential값은 nil
}

상기까지 에러 분석은 네트워크 연결여부와 관계없이 모두 동일한 에러메시지를 반환

단, 네트워크 미연결시에는 아래와 같은 추가 에러 메시지

애플 게임 센터 Auth 자체를 생성하게 되는 경우, Firebase database 데이터 연동까지 잘 넘어가는지 확인해볼 필요 있음
