title: A fail concerning the expression @autoreleasepool
body: <p>I downloaded a sample code from developer.apple.com  called  <a href="http://developer.apple.com/library/ios/#samplecode/SimpleGestureRecognizers/Listings/Classes_GestureRecognizerViewController_m.html#//apple_ref/doc/uid/DTS40009460-Classes_GestureRecognizerViewController_m-DontLinkElementID_4" rel="nofollow">SimpleGestureRecognizer</a> and in the main.m the program send a fail, because the program does not know the expression @auoreleasepool</p>
  
  <p>The fail is: Unexpected '@' in program.
  I searched on the internet, if there is a same problem happens to someone, but there was nobody having the same problem.</p>
  
  <p>Do you know, why this program does not know the expression @autoreleasepool?
  My Xcode version is 3.2.6</p>
  
  <p>Thank you for your help and presumptions in forward </p>
