title: Customize FSCalendar for RTL
body: <p>How do I configure FSCalendar to support RTL language numerals ?</p>
  
  <p>Here's the code I'm using </p>
  
  <pre><code>FSCalendar *calendar = [[FSCalendar alloc] initWithFrame:CGRectMake(0, 0, 300, 320)];
  calendar.dataSource = self;
  calendar.delegate = self;
  calendar.backgroundColor = [UIColor whiteColor];
  calendar.appearance.headerMinimumDissolvedAlpha = 0;
  calendar.appearance.caseOptions = FSCalendarCaseOptionsHeaderUsesUpperCase;
  calendar.scrollDirection = FSCalendarScrollDirectionHorizontal;
  calendar.locale = [[NSLocale alloc] initWithLocaleIdentifier:@"ar_AE"];
  </code></pre>
  
  <p>When I launch the calendar view, I cannot get the dates to display using the correct language numerals</p>

  As you can see only partial content is displayed correctly. I'm on iOS 10.</p>
  
  <p>@WenchaoD Any thoughts on how to get this to work ?</p>
