I’m working on client/server application which uses AsyncSocket. For transferring data, it uses NSData.
How can I insert my custom object, containing NSNumbers, NSIntegers, and NSStrings into an NSData object and then get it back out?
One way to insert (serialize) a custom object into an NSData object is to use NSCoding and NSKeyedArchiver.
First, have your custom object implement the NSCoding protocol.
Example here:

Then, for information on using your object with NSKeyedArchiver refer to:

Hope that helps!
