title: Obj-C - NSPredicate filter key containing space in its title?
body: <p>I have a key (field) in my database that contains a space in its name (don't get me started, lol...). I'm trying to use NSPredicate to filter the values in this key. How can I write the following string to account for the space in the key title 'off leash'?</p>
  <pre><code>self.restSubFilter = [self.neighbourhoodData filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@&quot;(off leash contains[c] %@)&quot;, @&quot;YES&quot;]];
  </code></pre>
