Connecting to C# Server from iOS

Question

I am trying to make an iOS apps which connects to a C# server (using TCP) programmed similarly to that shown here . On the client (iOS) side, I use CFStreams and the CFStreamCreatePairWithSocketToHost method to connect to my cloud server. I have followed the tutorial found here precisely for the iOS side. A copy of the main connection program can be found here .

Unfortunately, when I run the app, I never get a NSStreamEventHasBytesAvailable event from the inputStream, even though the server is programmed to send a message to the client immediately after the connection has been made. Can someone help me fix this?

All help is greatly appreciated, and I always accept at least one answer!

Answer 1

You may want to print out on the server side what was received and what was sent. And you may want to read this, as he does a good job of giving ideas of how to get more info:

bytesWritten, but other device never receives NSStreamEventHasBytesAvailable event
