Question

I am a newbie in XCode4.3.

As mentioned in title, how should I use http method PUT to send a json data to my server?

My json is as follows:

{"password":"11111111","nickname":"yo", "email_address":"[e-mail]"}

You’ll need NSURLRequest and then NSURLConnection objects. Your view controller can then implement the NSURLConnectionDelegate protocol, and handle the response from the server. These links should get you going in the right direction.

The basic pattern is this:

1. Initialize a request with your body and method, etc
2. make a connection with it and set yourself as the delegate
3. handle the connection callbacks, building up an NSData of the response bytes
4. handle the connection’s final callback connectionDidFinishLoading: to actually do something with your UI based on the response.
