title: FSCalendar+Persian: How to change weekday order?
body: <p>I'm using Objective-c in my project, and using FSCalendar+Persian pod.</p>
  <p>this is my code for showing calendar:</p>
  <pre><code>calendar = [[FSCalendar alloc] initWithFrame:CGRectMake(0, 0, _calendarContainer.frame.size.width, _calendarContainer.frame.size.height)];
  calendar.locale = [NSLocale localeWithLocaleIdentifier:@&quot;fa_IR&quot;];
  calendar.calendarIdentifier = NSCalendarIdentifierPersian;
  calendar.firstWeekday = 1;
  calendar.placeholderType = FSCalendarPlaceholderTypeNone;
  calendar.dataSource = self;
  calendar.delegate = self;
  
  calendar.appearance.headerTitleColor = [UIColor primaryColor];
  calendar.appearance.headerTitleFont = [UIFont fontWithName:NSLocalizedString(@&quot;DefaultFontBold&quot;, @&quot;&quot;) size:15];
  calendar.appearance.weekdayTextColor = [UIColor primaryColor];
  
  calendar.appearance.selectionColor = [UIColor clearColor];
  calendar.appearance.borderSelectionColor = [UIColor primaryColor];
  calendar.appearance.titleSelectionColor = [UIColor primaryColor];
  
  calendar.appearance.titleDefaultColor = [UIColor primaryColor];
  
  calendar.appearance.todayColor = [UIColor primaryColor];
  calendar.appearance.titleTodayColor = [UIColor whiteColor];
  
  calendar.appearance.titleFont = [UIFont fontWithName:NSLocalizedString(@&quot;DefaultFont&quot;, @&quot;&quot;) size:14];
  
  calendar.appearance.titleWeekendColor = [UIColor redColor];
  calendar.calendarWeekdayView.weekdayLabels[5].textColor = [UIColor redColor];
  
  [_calendarContainer addSubview:calendar];
  </code></pre>
