title: IOS Upgrade to 7.0 Issue With Dictionary Lookup
body: <p>Using location Manager in an app the following code worked prior to iOS7, now with iOS7, I'm getting the "??" escape.  I'm looking up the state to retrieve the state abbreviation.  The location mananger is properly retrieving the State (if I code to use "state" it will give me the desired state), but the lookup to the plist file (set to dictionary object) to get the abbreviation, for whatever reason fails and gives the "??" option. Any Ideas what's up?</p>
  
  <pre><code>NSString *state = placemark.administrativeArea;
  NSString *stateAbbreviation = [self.usStateAbbreviations objectForKey:[state uppercaseString]];
  NSString *stateTarget = state;
  
  if (stateAbbreviation) {
      stateTarget = stateAbbreviation;
  }else{
      stateTarget = @"??";
  }
  </code></pre>
