【问题描述】：
我正在使用 Multipeer 连接。当所有设备都连接到同一个 wifi 时，它可以正常工作。
我有 1 个主设备和 5 个从设备。我想与个人热点进行连接，但每次连接都会被拒绝。 我想使用个人热点将所有从设备与主设备连接以在它们之间共享数据。
这是我的代码：
class SessionManager: NSObject, MCSessionDelegate, MCBrowserViewControllerDelegate, MCNearbyServiceAdvertiserDelegate, MCNearbyServiceBrowserDelegate {
func browser(_ browser: MCNearbyServiceBrowser, foundPeer peerID: MCPeerID, withDiscoveryInfo info: [String: String] ? ) {
browser.invitePeer(peerID, to: mcSession, withContext: nil, timeout: 10)
}
func browser(_ browser: MCNearbyServiceBrowser, lostPeer peerID: MCPeerID) {
print("Lost Peer")
}
static
let shared = SessionManager()
var peerID = MCPeerID(displayName: UIDevice.current.name)
var mcSession: MCSession!
var mcAdvertiserAssistant: MCAdvertiserAssistant!
var delegate: SessionDelegate!
var serviceBrowser: MCNearbyServiceBrowser
var serviceAdvertiser: MCNearbyServiceAdvertiser
override init() {
serviceBrowser = MCNearbyServiceBrowser(peer: peerID, serviceType: "demo")
serviceAdvertiser = MCNearbyServiceAdvertiser(peer: peerID, discoveryInfo: nil, serviceType: "demo")
super.init()
peerID = MCPeerID(displayName: UIDevice.current.name)
mcSession = MCSession(peer: peerID, securityIdentity: nil, encryptionPreference: .required)
mcSession.delegate = self
serviceBrowser.delegate = self
serviceBrowser.startBrowsingForPeers()
serviceAdvertiser.delegate = self
serviceAdvertiser.startAdvertisingPeer()
}
//MARK: Start Hosting
func startHosting() {
mcAdvertiserAssistant = MCAdvertiserAssistant(serviceType: "demo", discoveryInfo: nil, session: mcSession)
mcAdvertiserAssistant.start()
}
//MARK: Join Session
func joinSession() {
let mcBrowser = MCBrowserViewController(serviceType: "demo", session: mcSession)
mcBrowser.delegate = self
mcBrowser.navigationController ? .navigationBar.backgroundColor = .black
UINavigationBar.appearance().tintColor = .black
UIApplication.visibleViewController.present(mcBrowser, animated: true)
}
//MARK: Delegate Methods
func session(_ session: MCSession, didReceive stream: InputStream, withName streamName: String, fromPeer peerID: MCPeerID) {}
func session(_ session: MCSession, didStartReceivingResourceWithName resourceName: String, fromPeer peerID: MCPeerID, with progress: Progress) {}
func session(_ session: MCSession, didFinishReceivingResourceWithName resourceName: String, fromPeer peerID: MCPeerID, at localURL: URL ? , withError error : Error ? ) {}
func browserViewControllerDidFinish(_ browserViewController: MCBrowserViewController) {
UIApplication.visibleViewController.dismiss(animated: true, completion: nil)
}
func browserViewControllerWasCancelled(_ browserViewController: MCBrowserViewController) {
UIApplication.visibleViewController.dismiss(animated: true, completion: nil)
}
func session(_ session: MCSession, peer peerID: MCPeerID, didChange state: MCSessionState) {
switch state {
case MCSessionState.connected:
print("Connected:SessionManager \(peerID.displayName)")
case MCSessionState.connecting:
print("Connecting:SessionManager \(peerID.displayName)")
case MCSessionState.notConnected:
print("Not Connected:SessionManager \(peerID.displayName)")
}
}
func session(_ session: MCSession, didReceive data: Data, fromPeer peerID: MCPeerID) {
let sessionData = SessionModel.init(session, peerID, data)
delegate.didRecieveSessionData(sessionData)
}
func advertiser(_ advertiser: MCNearbyServiceAdvertiser, didReceiveInvitationFromPeer peerID: MCPeerID, withContext context: Data ? , invitationHandler : @escaping(Bool, MCSession ? ) - > Void) {
print("Receive Invitation")
invitationHandler(true, self.mcSession)
}
func advertiser(_ advertiser: MCNearbyServiceAdvertiser, didNotStartAdvertisingPeer error: Error) {
print("Ddn't Start")
}
}
有什么办法可以做到这一点。
任何帮助将不胜感激。
