title: Server-Client based just on iOS devices
body: <p>I want to communicate among iOS devices via wifi using socket. There is an iOS devices play server role (open listening socket to wait for another). Other devices will be clients and use their socket connect to the server iOS device.I am not allow to communicate via any web server, just among these iOS devices. </p>
  
  <p>Is there any simple solutions for this, may be tell me briefly what I can use. if just using Objective C, it will be better.</p>
  
  <p>Thanks.</p>
