Question

在Android上我这样做是用一个简单的attacched地图创建一个服务广播作为信息

HashMap<String, String> record = new HashMap<>();
record.put("info, "my android info");    
WifiP2pDnsSdServiceInfo serviceInfo = WifiP2pDnsSdServiceInfo
        .newInstance("_myservice", "_tcp", record);
WifiP2pManager manager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
Channel channel = manager.initialize(this, this.getMainLooper(), null);
manager.addLocalService(channel, serviceInfo, null);

检索另一个信号

manager.setDnsSdResponseListeners(channel, this, this);

@Override
public void onDnsSdTxtRecordAvailable(String fullDomainName, Map<String, String> txtRecordMap, WifiP2pDevice srcDevice)

在iOS上，它是相同的服务名称和信息地图

MCPeerID* _myPeerId=[[MCPeerID alloc] initWithDisplayName:@"my ios peer"];
NSDictionary* _serviceInfo=@{@"info": @"my ios info"};

MCNearbyServiceAdvertiser* _serviceAdvertiser = [[MCNearbyServiceAdvertiser alloc] 
         initWithPeer:_myPeerId discoveryInfo:_serviceInfo serviceType:@"myservice"];
_serviceAdvertiser.delegate=advertiseDelegate;

MCNearbyServiceBrowser* _serviceBrowser=[[MCNearbyServiceBrowser alloc] 
      initWithPeer:_myPeerId serviceType:@"myservice"];
_serviceBrowser.delegate=browserDelegate;

[_serviceAdvertiser startAdvertisingPeer];
[_serviceBrowser startBrowsingForPeers];

和代表

-(void)browser:(MCNearbyServiceBrowser *)browser lostPeer:(MCPeerID *)peerID
-(void)browser:(MCNearbyServiceBrowser *)browser foundPeer:(MCPeerID *)peerID withDiscoveryInfo:(NSDictionary<NSString *,NSString *> *)info

Android设备只能在iOS设备之间看到另一个Android设备。但是，这两个家庭看不到对方。无论操作系统如何，我都想让其他设备看到它们。
