多点连接广告商

Question

我有一个 class 实现了 MCNearbyServiceAdvertiserDelegate。初始化后，如果我调用 MPCManager.advertiser.startadvertisingpeer()，我可以从客户端看到通告的对等点。我正在尝试实施一种方法来停止广告，更改广告商发现信息，然后使用新的发现信息再次开始广告。

这些方法成功地停止了通告对等方，但它没有再次开始通告。你能帮我吗

代码详情

classMPCManager:NSObject,MCSessionDelegate,MCNearbyServiceBrowserDelegate, MCNearbyServiceAdvertiserDelegate {

var delegate: MPCManagerDelegate?

var session: MCSession!
var sessionList: [MCSession]! = []
var peer: MCPeerID!

var browser: MCNearbyServiceBrowser!

var advertiser: MCNearbyServiceAdvertiser!

var foundPeers:[NSDictionary]! = [] 

var invitationHandler: ((Bool, MCSession!)->Void)!

var discoveryInfo:[String: String]!

init(discoveryInfo:[String:String]!, peer:MCPeerID!) {
    super.init()
    self.discoveryInfo = discoveryInfo
    self.peer = peer
    session = MCSession(peer: self.peer)
    session.delegate = self
    browser = MCNearbyServiceBrowser(peer: peer, serviceType: "myservicetype")
    browser.delegate = self
    advertiser = MCNearbyServiceAdvertiser(peer: self.peer, discoveryInfo: self.discoveryInfo, serviceType: "myservicetype")
    advertiser.delegate = self
}
 /////some other methods
///the problematic method
 func setAdvertising(discoveryInfo:[String:String]!){
    print("setting advertising")
    self.discoveryInfo = discoveryInfo
    advertiser.stopAdvertisingPeer()
    advertiser = nil
    self.advertiser =  MCNearbyServiceAdvertiser(peer: self.peer, discoveryInfo: self.discoveryInfo, serviceType: "myservicetype")
   self.advertiser.delegate = self
   print("advertising from set advertising")
   advertiser.startAdvertisingPeer()
 }

终于成功了。我在另一篇文章中寻求将发现信息用作字典而不是 [String:String] 奇怪的东西，但它现在可以工作了 :D!。感谢大家花时间阅读
