title: App rejected, but I don't use UDID
body: <p>Today we received a feedback about our submission and we do not understand the reported problem: "Apps are not permitted to access the UDID and must not use the uniqueIdentifier method of UIDevice. Please update your apps and servers to associate users with the Vendor or Advertising identifiers introduced in iOS 6.".</p>
  
  <p>We know about the rejections about udid, but our App do not use this! After read this, our team reevaluated the App and we do not found occurrences from "UIDevice uniqueIdentifier". We also revised all used libraries and really we do not find any call from UDID.</p>
  
  <p>Someone have ideas?</p>
  
  <p>After research, I executed "greap" command and I am suspecting about FacebookSDK:</p>
  
  <pre><code>my-app-directory $ grep -Rnis 'uniqueIdentifier' *
  Binary file MyApp/FacebookSDK.framework/FacebookSDK matches
  Binary file MyApp/FacebookSDK.framework/Versions/A/FacebookSDK matches
  Binary file MyApp/FacebookSDK.framework/Versions/Current/FacebookSDK matches
  Binary file MyApp/MyApp.xcodeproj/project.xcworkspace/xcuserdata/myuser.xcuserdatad/UserInterfaceState.xcuserstate matches
  </code></pre>
  
  <p>FacebookSDK uses uniqueIdentifier?? Whats the resolution?</p>
