Swift：MCSession连接，但从未完全连接

Question

我在swift中有一个对象来管理MCSessions并连接到它找到的任何对象。但是，似乎总是存在一些问题，因此当它连接到会话时，它会断开连接。

func browser(browser: MCNearbyServiceBrowser, foundPeer peerID: MCPeerID, withDiscoveryInfo info: [String : String]?) {
    browser.invitePeer(peerID, toSession: session, withContext: nil, timeout: 10)
    print("Found someone looking for a session to join: " + peerID.displayName);

}
//Error function
func advertiser(advertiser: MCNearbyServiceAdvertiser, didNotStartAdvertisingPeer error: NSError) {
    print(error.localizedDescription)
}
func browser(browser: MCNearbyServiceBrowser, lostPeer peerID: MCPeerID) {
    //Do something when we lost a connection to someone.
}

// Remote peer changed state.
func session(session: MCSession, peer peerID: MCPeerID, didChangeState state: MCSessionState){
    print("WE HAVE A PEER THATS CHANGING");
    var str = "";
    switch(state){
    case .NotConnected: str = "Not Connected";
    case .Connecting: str = "Connecting";
    case .Connected: str="Connected";
    }
    print("Count: " + String(session.connectedPeers.count) + " State: " + str);
}

观察人们对此的其他问题，几乎总是由广告客户，浏览器和会话之间的MCPeerID不同引起的。但是，我明确地为整个类设置了一个常量peerID。

    let devicePeerID = MCPeerID(displayName: UIDevice.currentDevice().name)
