title: Get text from a pdf in NSString
body: <p>I am trying to make an iOS app which would extract plain text from a pdf file and display it in a <code>UITextView</code>. Its simply not a pdf reader to view a pdf file but i would later wish to perform certain operations on that text. 
  I have already googled a lot but still not able to get an exact solution.</p>
  
  <p>i already tried using <a href="https://github.com/zachron/pdfiphone" rel="nofollow">https://github.com/zachron/pdfiphone</a> 
  but the files are using ARMV6 architecture which seems obsolete with xcode 4.5</p>
  
  <p>And if anyone can suggest some exact and non-confusing code using Quartz-2d framework of iOS then it would be great. </p>
