Get taxonomy term store in iOS SharePoint client

Question

I couldn't get any lead info on how to retrieve a taxonomy term store using REST API in an iOS app.

Any information will be highly appreciated. Thanks.

EDIT

According to this article, managed taxonomy data cannot be consumed from REST.

Though, this can be done using JSOM (sp.taxonomy.js), so it seems reasonable to ask if the same stuff can be ported to iOS or other platforms.

I managed to get taxonomy terms by POSTing this SOAP message to _vti_bin/TaxonomyClientService.asmx:

<?xml version='1.0' encoding='utf-8'?>
<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>
  <soap:Body>
    <GetKeywordTermsByGuids xmlns='http://schemas.microsoft.com/sharepoint/taxonomy/soap/'>
      <termIds>&lt;id&gt;64d031b6-76bb-49ec-a3b3-cb42b8f0953b&lt;/id&gt;</termIds>
    </GetKeywordTermsByGuids>
  </soap:Body>
</soap:Envelope>

If you need to include more than one guid in the termIds node, you must post it in an XML format like this:

<set>
  <id>guid1</id>
  <id>guid2</id>
  ...
</set>

and, of course, HTML escaped.
