IOS 앱 (IOS SDK 8.0)에 PubNub를 사용하고 있습니다. "applicationDidEnterBackground"이벤트에서 채널 구독을 취소하려고 할 때 다음 콘솔 출력이 표시됩니다. 채널의 구독이 취소되었지만 관리 콘솔에서 확인한 후에도 채널에 있습니다. 이것에 대해 조언을 해줄 수 있습니까?채널에서 아직 구독 취소되었습니다. 채널에 아직 있습니다.

다음 
PubNub.unsubscribeFromChannel(channelToReceive,{(list, err:PNError!)-> Void in 
     if(err != nil){ 
      println(err.localizedFailureReason) 
     } else { 
      println("Unsubscribed...") 
     } 
    })

는 "applicationDidEnterBackground :와"이벤트 이후의 PubNub 콘솔 출력입니다 : 사전에

응용 프로그램을 백그라운드에서 지속적으로 실행할 수없는 경우 앱이 백그라운드 실행 상태로 전환 할 때 해당 명령을 호출 할 수 없습니다. PubNub 클라이언트가 귀하의 응용 프로그램과 함께 중단되기 전에 당신은 몇 가지 요청을 수행하기 위해 콜백을 사용하려고 할 수 있습니다 배경에있는 동안 pubnub 어떤 알림을 전송하지 않았기 때문에

- (void)pubnubClient:(PubNub *)client willSuspendWithBlock:(void(^)(void(^)(void(^)(void))))preSuspensionBlock { 

    if ([client isConnected]) { 

     preSuspensionBlock(^(void(^completionBlock)(void)){ 

      // Do last calls here 
      // Always call this block as soon as required amount of tasks completed. 
      completionBlock(); 
     }]; 
    }); 
    } 
}

나는 똑같은 문제가 있습니다. @moonlight 코드를 사용해 보았지만 isConnected는 FALSE이므로 아무 일도 일어나지 않습니다. – GrandSteph

답을 자세히 설명해 주시겠습니까? willSuspendWithBlock은 배경을 입력하기 전에 호출되지 않고 포 그라운드로 돌아올 때 호출됩니다. 정말 실망 스럽습니다. 백그라운드로 가기 전에 채널에 알림을 보내야 만 간단하게 알 수 있습니다. 별로 자기가 좋아하지 않아 : ( – GrandSteph

당신은 여전히 ​​연결되어 있습니다. 더욱 까다로워지면 포 그라운드로 돌아올 때 대기중인 notif를 보냅니다.

Pubnub를 백그라운드에서 실행하려면 적절한 백그라운드 모드를 활성화해야합니다. 웹 소켓이 필요한 곳 ​​(pubnub에서도 사용) 왼쪽에서 프로젝트를 선택하고 기능 탭으로 이동하십시오. 여기에서 사용할 수있는 모든 배경 모드를 찾을 수 있습니다. Pubnub 들어, 나는 VOIP를 듣고 및 위치 업데이 트가 작동합니다.

개인적으로 위치 업데이트를 선택합니다. 실제 위치 서비스에 위치 서비스를 사용하지 않으면 Apple에서 앱을 거부합니다. Pubnub로 일부 연구를하는 것은 나에게 좋지만 전개 할 때 백그라운드에서 실행할 수 있으므로 HTTP 요청으로 전환 할 수 있습니다.
