title: Asynchronous methods in NSOperation
body: <p>I'm fetching some data from Facebook Connect (using the FBConnect Objective-C 2.0 framework) and I'm doing all that in an NSOperation. It is in an NSOperation because I have several other operations that run as well and this is one of them.</p>
  
  <p>The problem is that all the FBConnect calls are asynchronous. Because of this, the main method of the NSOperation quickly finishes and the operation is marked as completed.</p>
  
  <p>Is there some way to overcome this? It would appear there are no synchronous options in FBConnect!</p>
  
  <p>Many thanks,</p>
  
  <p>Mike</p>
