title: Good tutorials or good for using Core.Data in IOS 7
body: <p>I have been trying to use this <a href="http://www.codigator.com/tutorials/ios-core-data-tutorial-with-example/" rel="nofollow noreferrer">tutorial</a>.</p>
  
  <p>But I want it to be saved in a thread other than the main thread. So far I cannot get the above tutorial working?</p>
  
  <p>I have also tried <a href="https://stackoverflow.com/questions/20160246/saving-in-core-data-with-context-crashing">this</a></p>
  
  <p>Any ideas?</p>
