Special Points of the socket communication (Objetive-C) client and (Java) Server

Source: Internet
Author: User

Some time ago, during sokcet communication under Objetive-C, when the C ++ program was used as the server, everything was normal. When Java was used as the server, neither party received the data, after reading some documents, sort out the notes

1. Press enter and line feed at the end of the message.

When Objetive-C sends data, add "\ r \ n" to the end"

_ Datatosend = [nsdata datawithbytes: "This is a test \ n" Length: 15];

This is because the Java server uses functions similar to Readline () to read the content in the buffer.


2. The encoding method must correspond

ASCII code

Nsdata * Data = [[nsdata alloc] initwithdata: [Response datausingencoding: nsasciistringencoding];

UTF-8 Coding

Nsdata * Data = [[nsdata alloc] initwithdata: [Response datausingencoding: nsutf8stringencoding];


The same encoding method is used.
