title: Facebook graph API issue with the iOS SDK
body: <p>I'm having an issue with the Facebook graph API, and more precisely the iOS SDK. My code used to work properly but now I get this error description when trying do use it (to get personal feed, friend's feed, friends list,...) :</p>
  
  <pre><code>Err details: Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0x7113b80 {error=&lt;CFBasicHash 0x7113910 [0x176e400]&gt;{type = mutable dict, count = 2,
  entries =&gt;
      2 : &lt;CFString 0x7121e60 [0x176e400]&gt;{contents = "type"} = &lt;CFString 0x7113a20 [0x176e400]&gt;{contents = "OAuthException"}
      3 : &lt;CFString 0x7113b40 [0x176e400]&gt;{contents = "message"} = &lt;CFString 0x7113a00 [0x176e400]&gt;{contents = "An access token is required to request this resource."}
  }
  }
  </code></pre>
  
  <p>Would anyone have an idea of where it might come from ?</p>
  
  <p>Here is my source code too : </p>
  
  <pre><code>facebook = [[Facebook alloc] initWithAppId:@"00000000000000"];
      NSArray *permissions =  [[NSArray arrayWithObjects:@"read_stream", @"publish_stream", @"offline_access",nil] retain];
      [facebook authorize:permissions delegate:self];
      [facebook requestWithGraphPath:@"1342568689/feed" andDelegate:self];
  </code></pre>
