title: How to properly set up testflight in ios?
body: <p>I've installed Testflight SDK 1.2.4 for my iOS application. I'm using Xcode version: 4.6. Device: IOS 6.1. Also .ipa and .dSYM were uploaded.</p>
  <p>
  When I run Xcode, it shows following logs:</p>
  <p><i><b>
  TestFlight: Started Session<br>
  TestFlight: Crash Handlers are installed<br>
  TestFlight: App Token Error  - Your App Token is not recognized https://testflightapp.com<br>
  TestFlight: Checkpoint Passed - User_Check_Point<br>
  TestFlight: Communication with TestFlight is currently disabled, check earlier in your log for details <br>
  </b></i></p>
  <p>I'm sure App Token is exactly correct.
  Also in SDK Debugger there is only session started and ended report;
  </p>
  <p>Here my code:</p>
  <pre><code>-(BOOL)application:(UIApplication *)application 
      didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // start of your application:didFinishLaunchingWithOptions 
  // ...
  
  //#define TESTING 1
  //#ifdef TESTING
  //    NSUUID *uniqueIdentifier = [[UIDevice currentDevice] identifierForVendor];
  //    
  //    [TestFlight setDeviceIdentifier:[uniqueIdentifier UUIDString]];
  //#endif
      
      NSSetUncaughtExceptionHandler(&amp;HandleExceptions);
      // create the signal action structure
      struct sigaction newSignalAction;
      // initialize the signal action structure
      memset(&amp;newSignalAction, 0, sizeof(newSignalAction));
      // set SignalHandler as the handler in the signal action structure
      newSignalAction.sa_handler = &amp;SignalHandler;
      // set SignalHandler as the handlers for SIGABRT, SIGILL and SIGBUS
      sigaction(SIGABRT, &amp;newSignalAction, NULL);
      sigaction(SIGILL, &amp;newSignalAction, NULL);
      sigaction(SIGBUS, &amp;newSignalAction, NULL);
  
      [TestFlight takeOff:@&quot;my_app_token&quot;];
  
      // The rest of your application:didFinishLaunchingWithOptions method
  }
  </code></pre>
  <p>
  <p>Where is my error?! Please help me. Thanks in advance.</p>
