Answer 1

You can really just return that string as a body if you like. But you have to set the content type to "application/json" . One of these posts might help for doing that on ios?

How to set content-type when using initWithContentsOfUrl

JSON file set content type to application/json AFNetworking

setting content-type overwriting httpbody?

Answer 2

Everything looks ok with your code except you forgot to call buildPostBody method. After you set all body data you have to call this method.

[asiRequest buildPostBody];
[asiRequest startAsynchronous];

If this is a new project, I highly recommend to use any other up-to-date libraries. developers stopped developing ASIHTTPRequest long time ago.
