title: how to access online mongoDB data using IOS
body: <p>My friend has a website built using Pyramid framework and using MongoDB to store data. If I want to build an iPhone app, how do I access the data from that database? </p>
  
  <p>I know Obj-C and have built simple, iOS apps, but none of them used non-local data. I've googled but no good result returned. I just don't know where to start. Any good tutorial or sample code on the related issue would be appreciated!!</p>
