XMPPFramework - TURNSocket 收不到自己发送的数据？

Question

我用openfire作为xmpp服务器，想通过Turnsocket传输文件。

openfire（本地）配置：

xmpp.auth.anonymous                true
xmpp.domain                        local
xmpp.enabled                       true
xmpp.externalip                    proxy.local, 192.168.1.101, 127.0.0.1
xmpp.proxy.enabled                 true
xmpp.proxy.port                    7777
xmpp.proxy.transfer.required       false
xmpp.server.socket.active          true
xmpp.session.conflict.limit        0
xmpp.socket.ssl.active             true

我在本地环境下测试了文件传输，一个用户通过Simulator（Sender）登录，另一个用户通过Device（iPod，receiver）登录。

1. TURNSocket.m（均已更改），更改代理

   + (void)initialize {
       ...
       proxyCandidates = [[NSMutableArray alloc] initWithObjects:@"local", nil];
       ...
   }
   

2. 在发送者和接收者上都配置

   - (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq {
   
       ...
   
       if ([TURNSocket isNewStartTURNRequest:iq]) {
   
           NSLog(@"IS NEW TURN request Receive.. TURNSocket..................");
   
           TURNSocket *turnSocket = [[TURNSocket alloc] initWithStream:xmppStream incomingTURNRequest:iq];
           [turnSockets addObject:turnSocket];
           [turnSocket startWithDelegate:self delegateQueue:dispatch_get_main_queue()];
           [turnSocket release];
       }
       return YES;
   }
   

3. 设置和调用 TURNSocket (Sender)

   TURNSocket *turnSocket = [[TURNSocket alloc] initWithStream:[self xmppStream] toJID:user.primaryResource.jid];
   [turnSockets addObject:turnSocket];
   [turnSocket startWithDelegate:self delegateQueue:dispatch_get_main_queue()];
   [turnSocket release];
   

4. didSucceed 同时调用（发送者和接收者）

   - (void)turnSocket:(TURNSocket *)sender didSucceed:(GCDAsyncSocket *)socket {
   

   }

5. 发送文件？在发件人上

   - (void)turnSocket:(TURNSocket *)sender didSucceed:(GCDAsyncSocket *)socket {
   
       NSData *dataF = [[NSData alloc] initWithContentsOfFile:
                                      [[NSBundle mainBundle] pathForResource:@"a1" ofType:@"png"]];
   
       [socket writeData:dataF withTimeout:60.0f tag:0];
   }
   

   或者：这里接收到数据？ （接收者）

   - (void)turnSocket:(TURNSocket *)sender didSucceed:(GCDAsyncSocket *)socket {
   
       NSData *dataF = [[NSData alloc] init];
   
       [socket readDataToData:dataF withTimeout:30.0 tag:0];
       NSLog(@"dataF: %d", [dataF length]); //  dataF: 0
   }
   

有谁知道问题出在哪里？

非常感谢！

要设置外部ip地址，需要使用xmpp.proxy.externalip而不是xmpp.externalip
