title: NSDictionary inside NSDictionary
body: <p>Ok I have a .plist file, </p>
  
  <p>In which I have an <code>NSDictionary *StoredAddresses</code>, </p>
  
  <p>Inside <code>StoredAddresses</code>, is another handful of <code>NSDictionary</code></p>
  
  <p>I know I can use, </p>
  
  <pre><code>if ([dictionaryOfAddresses objectForKey:@"StoredAddresses"])
  </code></pre>
  
  <p>To access the top level NSDictionaries, but how can I search for keys inside the stored addresses? </p>
