iPhone socket program

Question

I want to create an extremely simple iPhone program that will open a telnet session on a lan-connected device and send a sequence of keystrokes. Most of the code I've seen for sockets is overwhelming and vast overkill for what I want to do:

1. open telnet socket to IP address
2. send ascii keystrokes

Any simple code examples out there I can play with?

Answer 1

Do yourself a favor: go read at least first 6 chapters of this Steven's book in which you can find plenty of simple examples and many advices how to avoid common pitfalls with network programming. Without doing that you will end with a buggy, slow and incomplete client.

Answer 2

I'd suggest you check out the Asyncsocket project:

It makes socket programming really easy; no messing with threads yourself and things happen asynchronously without much fuss.

I think there is a sample project with a client/server to get you started.

Answer 3

i cant repost my code here, because SO considers it spamming to repeat your answer.

check out this sample code and tutorial link. works like a charm and is really simple to implement, less than 3 minutes and you are up and going (IF you have a socket server ready).

Answer 4

Go through this you will have to get basic idea of socket programming
