title: How to print BOOLs
body: <p>I want to print a BOOL (which is documented to be a signed char) without any compiler warnings:</p>
  
  <pre><code>NSLog(@"Parsing Result = %hhd", parsingResult);
  
  //  inside some iOS program. Xocde 6
  </code></pre>
  
  <p>But I get "Format specifies type 'char' but the argument has type 'BOOL' (aka 'bool')".</p>
