NSNotificationCenter 알림이 전송되지/

Question

가

질문 대답했다 // basicly 내가 적은 더/코드를 잘해야합니다 :) 내 응용 프로그램이 시작 내가 먼저 시작 화면을로드 할 때

이되는 SplashScreen은 데이터 다운로드가 시작됩니다 받았을 때 화면 자체 수행 로딩 :

Splash.m는

는 는 는 알림 데이터를 분석 멀리 저장 될 때마다 DataManager에 다음 별도의 스레드에서 데이터를로드 및 구문 분석 Dataloader에 자사의 인스턴스를 사용하여 진행됩니다

DataLo에서 보낸 ader. 이전에 많은 경우에 알림 작업을했는데 이번에는 작동하지 않으며 이유를 파악할 수 없습니다. 오류 또는 기타 사항은 없지만 옵저버에 설정된 기능은 절대로 호출되지 않습니다. 무엇이 잘못되었는지에 대한 아이디어는 대단히 환영합니다. 여기, 그리고 다른 사이트에서 꽤 많은 글을 읽었지만 아직 내 대답을 찾지 못했습니다.

Answer 1

, 당신은 return 문 전에 등록 코드를 삽입해야합니다. 그렇지 않으면 절대 실행되지 않습니다.

건배!
