macOS Using NSUrl for xml http get

[ltt]

Hi,

I am a new Objective-C Developer with mild C and Delphi experience. I am finding it hard to adapt to Objective-C. I can see the benefits, but I am still getting my head around the syntax.

I have what I consider a really simple app to write but I can not for the life of me work out how to do it! Can anyone help?
I believe I need to use NSUrl somehow.

The requirement;

I need to send an XML request to a specific url and do a http get, then write the results to a file. An example request and result is shown below.

An example request would be:

<request method="[method name]">
<!-- method arguments -->
</request>

I expect a successful response like;

<response status="ok">
<!-- return value(s) here] -->
</response>

I need to write the returned values to a file.

Unsucessful response like;

<response status="fail">
<error> ... </error>
</response>

I need to display the error message to NSLog.

I can use curl to get the response using the following command;
curl -u insert_token_here:X https://mydomain.com/xmlrequest -d '[xml body here]

Thanks in advance. Comments would be great to I can learn from your response.

Regards,
Luke.

general tips?

I know its a very specific request, but if no one has an example function, is there any way someone could give me some steps/pointers?

How can I get NSURL to send a request and accept data?

What functions/properties of NSURL do I need to research?

Regards,
Luke

What have you tried?

Have you done any research at all on NSURL? Have you read the programming guide? The class reference?

http://developer.apple.com/mac/libr.../Classes/NSURL_Class/Reference/Reference.html

There are several links to sample code in the NSURL class reference? Have you looked at those?

If you're more experienced with C, and your goal is to solve a problem rather than learn about NSURL, then maybe you should use libcurl to get your data.
