As Jan points out in his answer, you can use standard network APIs such as BSD, such as socket(), connect()etc. However, if you want to stay in Objective-C and Foundation, then you are looking for NSInputStreamand NSOutputStreamwhich are the flow classes for Cocoa. However, you should not look at it NSSocketPortas being specifically designed to use distributed objects.
