Server is how decoding. Originally, I have encountered, because the server using GBK encoding. What you need to look up the server encoding, database what is coded. Need unity.

This encounter, based on your description, I analyzed the reasons may be as follows:
The encoded data to the server is UTF-8, see the server is garbled, it indicates that the server could not parse the data using UTF-8, using the Chinese operating system, the default encoding is GBK, Microsoft officials said so.

Best to allow the server to check. The corresponding data is stored locally as utf8 format, open look is not normal. It is easy to see out.

Try it with the middle two
[Request setHTTPMethod: @ "POST"];
[Request setValue: postLength forHTTPHeaderField: @ "Content-Length"];
[Request setValue: @ "application / x-www-form-urlencoded" forHTTPHeaderField: @ "Content-Type"];
[Request setHTTPBody: postData];
