OK, the reason reading data doesn't work is because you aren't waiting
for the delegate calls to tell you that data is available; you're just
opening the stream and then immediately trying to read. It takes time
to open a socket and receive data over it.
You should really read the conceptual overview docs for Cocoa streams
before going any further. They include snippets showing how the
delegate calls work. Also, the sample code CocoaEcho shows how to
write a TCP client app that connects to a server and receives data.
