멀티 페어 연결성 진행률 표시 줄이있는 피어 투 피어 연결.

Question

나는이 일을 얼마 동안 해왔다. (주) 발신자와 수신자 모두에서 피어 투 피어 연결에 % 완료를 나타내는 레이블이있는 진행률 또는 활동 표시기를 추가 할 위치와 방법을 보여줄 수 있습니까?

내 작품.

//New Variable for spinner. 
    var spinnerOnOff = "" 

    //New Function to start, stop, hide and unhide spinner. 
    func spin(){ 
    if spinnerOnOff == "on"{ 
     activityIndicatorOutlet.isHidden = false 
     activityIndicatorOutlet.startAnimating() 
    }else{ 
     activityIndicatorOutlet.isHidden = true 
     activityIndicatorOutlet.stopAnimating() 
    } 
} 


//Updated function. (code block will ran "Quickly")

구현 한 MCSessionDelegate 기능을 사용해야합니다.

func session(MCSession, didStartReceivingResourceWithName: String, fromPeer: MCPeerID, with: Progress) 

진행률 개체를 사용하여 전송을 취소하거나 진행 상황을 확인할 수 있습니다.

데이터를 보내는 동안 데이터를 보내는 데 사용 된 함수의 완료 핸들러를 사용할 수 있습니다.

func sendResource(at resourceURL: URL, 
    withName resourceName: String, 
     toPeer peerID: MCPeerID, withCompletionHandler completionHandler: ((Error?) -> Void)? = nil) -> Progress? 

다시 진행률 개체를 사용하여 진행 상황을 추적 할 수 있습니다.

iOS 10에서 MultipeerConnectivity를 사용해 본 적이 있고 작동하는 경우 알려 주시기 바랍니다. 나는 지난 주 전체를 시도해 왔지만 그것은 동료와 연결되어 있지 않습니다. (감사합니다)

희망이 도움이됩니다.
