title: Get all days of any month with objective-c
body: <p>A seemingly simple question...how can I return a list of days for any specified month?</p>
  
  <pre><code>NSDate *today = [NSDate date]; //Get a date object for today's date
  NSCalendar *c = [NSCalendar currentCalendar];
  NSRange days = [c rangeOfUnit:NSDayCalendarUnit 
                         inUnit:NSMonthCalendarUnit 
                        forDate:today];
  </code></pre>
  
  <p>I basically want to use that, but replace <code>today</code> with say, the month of January, so I can return all of those days</p>
