Hi: I am working on a project which I am going to implement an UI for IPad while the original UI is written in Python. Here is a Python script written in the original UI: Code: msg = '%8s\0%8s\0%8s\0%s\0'(dst,code,appcode,data) size = len(msg)+9 msg='%8s\0%s'(size,msg) I need to make the same message and put it into the NSStream for sending to a remote server. How can I convert the script into NSString format? Thanks. Thanks in advance.
