    <p>I want to implement <a href="http://socket.io/" rel="nofollow">SocketIO</a> in my project. </p> <p>The serverside and client side codes for my project is given below. </p> <p>At the client side, there is a test button which sends a post request(<code>[self.afn post:@"/test" withParams:@{} completion:^(id obj{})]</code>) to the server side. self.afn is my instance object of my wrapper class for <a href="https://github.com/AFNetworking/AFNetworking" rel="nofollow">AFNetworking library</a>.</p> <p>The server side catches this post request with the function <code>app.post('test', function(){...}</code> In this post request handler, I emit a data(<code>{hello: "world"}</code>) at the <code>news</code>channel and I expect to catch this data on the client side in the <code>didReceiveMessage</code> handler of the <a href="https://github.com/pkyeck/socket.IO-objc" rel="nofollow">SocketIO library for Objective C</a>.</p> <p>I checked that, the button successfully sends the post request, and server side successfully handles this post request and emits the data(<code>hello:"world"</code>) on the <code>news</code> channel. However, client side does not catch this data on the <code>didReceiveMessage</code> handler.</p> <p>Where is the problem? Do you have any idea?</p> <p>The details of the codes for server and client side are given below:</p> <p>The ServerSide:</p> <pre><code>//server.js var express = require('express'); var app = module.exports = express(); /* configure app ... */ var io = require('socket.io').listen(8090); var mySocket; io.sockets.on('connection', function (socket) { mySocket = socket; }); app.post("/test", function(req, res){ if(mySocket){ mySocket.emit('news', { hello: "world"}); } }); </code></pre> <p>The ClientSide:</p> <pre><code>//Client side in ObjectiveC @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; self.txtFrom.delegate = self; self.txtTo.delegate = self; //initialize socket self.socket = [[SocketIO alloc] initWithDelegate:self]; [self.socket connectToHost: @"172.20.10.5" onPort:8090]; } // IBAction for the test button to send a post request to the server to activate - (IBAction)actTest:(id)sender { //self.afn is my wrapper class for AFNetworking [self.afn post:@"/test" withParams:@{@"foo": @"bar"} completion:^(id responseObj){ NSLog(@"Response object: %@", responseObj); }]; } - (void) socketIO:(SocketIO *)socket didReceiveMessage:(SocketIOPacket *)packet { NSLog(@"didReceiveMessage() &gt;&gt;&gt; data: %@", packet.data); } @end </code></pre> <p><strong>EDIT:</strong></p> <p>I followed the suggestion of Mathieu 'OtaK' Amiot and changed <code>[self.socket connectToHost: @"172.20.10.5" onPort:8090 withParams:nil withNamespace:@"news"];</code>to <code>[self.socket connectToHost: @"172.20.10.5" onPort:8090];</code></p> <p>Now, I can see the message at the console, however, when the message is received at the client side, <code>didReceiveMessage</code>handler does not invoked. </p> <p>When I'm sending the message from sender, the name of the event is "news", but in the client side I did not mention an event name. Can this be the reason? </p>

    1. COi have no great experience with `C#` but try to consider node.js as your server-side, i believe it would save you a lot of time.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
