연결 직후 서버 연결 해제

Question

Bonjour를 사용하는 동일한 서비스를 사용하는 다른 장치와 연결을 설정하기 위해 GCDAsyncsocket Library를 사용하여 Singleton Class를 작성했습니다. 나는 또 다른 장치 (클라이언트) 난에서 사용할 수있는 장치를 찾아 "StartBrowsing"를 호출 오전의 응용 프로그램에서, 그것은 호스트 (서버)로 설정하려면 "startPublishing을"의 방법을 사용하고 하나 개의 장치에

회로망. 사용자가 해당 네트워크에서 서비스 중 하나를 선택하면 "initConnectionWithService"메서드를 호출하고 연결할 NetService의 주소를 확인하여 연결 흐름을 시작합니다.

BonjourUtilClass.h 매우 예상치 못한 일이 happending 위의 것을 실행, 클라이언트 역할을하는 장치에 BonjourUtilClass.m

+(id)sharedInstance{ 
    if(!sharedObject){ 
     sharedObject = [[BonjourUtilClass alloc]init];

가 연결됨 호스트가이고 immediatly 다른 콜백이 올 것입니다. di Paulw11의 서버 장치에 클라이언트 장치

Answer 1

코멘트 솔루션을 찾기 위해 저를 도왔다. 사실 클라이언트쪽에 Socket을 저장했지만, 콜백 메소드 "didAcceptNewSocket"을 가져 오는 새로운 소켓에 대한 참조를 저장하는 것을 잊어 버렸습니다.

그래서 didAcceptNewSocket 방법은 다음과 같아야 newSocket이 방법에서 수신되도록

-(void)socket:(GCDAsyncSocket *)sock didAcceptNewSocket:(GCDAsyncSocket *)newSocket{ 
    NSLog(@"Accepted new Socket: HOST : %@ , CONNECTION PORT :%li",newSocket.connectedHost,(long)newSocket.connectedPort); 
    socketConnected = newSocket; 
} 

추가 통신을 유지할 수있다. 이전의 경우에는 메소드가 끝날 때 해제되었습니다.
