title: How to iterate over an dictionary without knowing the keys, while getting key and object?
body: <p>I have an NSDictionary and want to iterate over the objects. But at the same time, I need to know the key of the dictionary.</p>
  
  <p>I remember there was a special, fancy form of fast enumeration, but have forgotten the exact syntax.</p>
  
  <p>Anyone?</p>
