通过在IOS中使用XMPPFrameWork XEP-0065和XEP-0096进行FileTransfer

Question

我在IOS中有很多关于文件传输的搜索。我正在使用XEP-0065和XEP-0096进行FileTransfer。我正在使用的代码：

- (void)sendToOtherDevice:(NSData *)fileData receiverJid:(NSString *)receiverJid
{

     NSString *s = [NSString stringWithFormat:@"%@/Smack",receiverJid];
    XMPPJID *jid = [XMPPJID jidWithString:s];

//    XMPPSIFileTransfer * sifiletransfer = [[XMPPSIFileTransfer alloc] initiateFileTransferTo:jid withData:fileData];

    XMPPSIFileTransfer *sifiletransfer = [[XMPPSIFileTransfer alloc] init];
    [sifiletransfer initiateFileTransferTo:jid withData:fileData];
    //XMPPJID *jid = [XMPPJID jidWithString:receiverJid];


    NSString *jabbarID = [[[[self appDelegate] xmppStream] myJID] bare];
     XMPPJID *senderjid = [XMPPJID jidWithString:jabbarID];

    //[TURNSocket setProxyCandidates:[NSArray arrayWithObjects:s, nil]];
  // [TURNSocket setProxyCandidates:[NSArray arrayWithObjects:s,jabbarID, nil]];

    [TURNSocket setProxyCandidates:[NSArray arrayWithObjects:jid.domain,senderjid.domain, nil]];

   // [TURNSocket setProxyCandidates:[NSArray arrayWithObjects:jid.domain, nil]];
    //[TURNSocket setProxyCandidates:[NSArray arrayWithObjects:@"111.11.111.111", nil]];

     TURNSocket *socket1 = [[TURNSocket alloc] initWithStream:[self xmppStream] toJID:jid];

   // [turnSockets addObject:turnSocket];
    [socket1 startWithDelegate:self delegateQueue:dispatch_get_main_queue()];

}


-(void)turnSocket:(TURNSocket *)sender didSucceed:(GCDAsyncSocket *)socket
{
     [socket writeData:photoData withTimeout:60.0f tag:0];
     [socket disconnectAfterWriting];
}

- (void)turnSocketDidFail:(TURNSocket *)sender
{

    NSLog(@"Couldn't set up bytestream for file transfer!");
}

我找到了以下XML节：

请让我知道我做错了什么。我如何使用XEP-0096进行FileTransfer。
