title: iPhone NSNumberFormatter setFormat:
body: <p>It appears as though <code>NSNumberFormatter's</code> method for setting custom <code>formatters</code>. <code>setFormat:</code> isn't available on the iPhone...</p>
  
  <p>SO this... crashes my app:</p>
  
  <pre><code>NSNumberFormatter *lengthFormatter = [[NSNumberFormatter alloc] init];
  [lengthFormatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
  [lengthFormatter setNumberStyle:NSNumberFormatterDecimalStyle];
  [lengthFormatter setFormat:@"#,##0.0M"];
  </code></pre>
  
  <p>Has this occurred to anyone else?</p>
  
  <p>Thanks,</p>
  
  <p>Dan 
  **ANSWERED BELOW. <code>NSNumberFormatter</code> also has methods called <code>setPositiveFormat: setNegativeFormat:</code> which replace the depreciated <code>setFormat:</code> **</p>
