objective c - What is the iOS equivalent to Android Socket programming code?

Question

I have some socket programming code in Android (Java) and I want to implement the same thing in iOS (Objective-C).

On iOS, NSStream, NSInputStream, NSOutputStream are some of the classes for socket programming.

I have doubts when comparing them to some methods on Android's SocketChannel class.

socketChannel.configureBlocking
socketChannel.setSoTimeout
socketChannel.connect 
socketChannel.finishConnect
socketChannel.isConnected

What are the equivalent methods in iOS classes like NSStream, NSInputStream?

And also ByteBuffer on Android has a position() method. What is the equivalent method in iOS?

I know the NSStream constants are there, but I am confused about how they map to Android code. Could you please suggest which methods are equivalent in iOS?

Answer 1

You don't translate code line by line. Different platforms and even different frameworks use different styles of API.

Since your question doesn't say what you are trying to do, I can only recommend that you read more about how stream and socket programming works on iOS in

• the Stream Programming Guide, or
• the CFNetwork Programming Guide (if you want to read more about lower level (Core Foundation) networking code on iOS), or
• the Networking Overview (if you want to read more about networking code in general on iOS)
