how to use NSStream class to create tcp connection iPhone

I need to send a string to a server on the same network with the iPad. when reading This I found out that maybe I need to use the + getStreamsToHost:port:inputStream:outputStream: method but I am not able use it. In 开发者_如何学Pythonxcode I have tried:

//Try 1
NSStream *myStream;
//[myStream getStreamToHost// xcode cant find it]

//Try 2
NSStream *myStream2 = [[NSStream alloc] init];
[myStream2 getStreamToHost// I have initialized it and yet xcode can't find the method


//Try 3
[NSStream getStreamToHost] // does not work eather

 //Try 4
 [[[NSStream alloc] init] getStreamToHost// does not work

and by the way I am listening on port 403 with a simple program called autoit let me show you how:

I have two scripts (the client and the server);

first I run the server and it starts listening. Then I run the client script and when that happens a message box appears and a song starts playing:

Let me show you the code it is very simple to understand just to show what's going on...

the client code:

and the server code:

note that the client sends the message hello and when that happens a message box appears MsgBox(0,"Data Received", $TCPReceive) and a song starts playing shellExecute("t.mp3") that mp3 file is on the same directory of the script.

HOW CAN I SEND A SIMILAR MESSAGE BUT WITH AN IPHONE TO MY COMPUTER?

+getStreamsToHost:port:inputStream:outputStream: is a class method (indicated by the +), so you have to use [NSStream getStreams...] instead of [[[NSStream alloc] init] getStreams...].
