The CLWeeklyCalendarView class miss a method named "setNeedsDisplay"

I change the CLCalendarBackgroundImageColor, but the new color can't be displayed.

For now I only see to fix it by adding the line:
_backgroundImageView.backgroundColor = self.backgroundImageColor? self.backgroundImageColor : [UIColor colorWithPatternImage:[UIImage calendarBackgroundImage:self.bounds.size.height]];
directly into the (void)applyCusomDefaults. Is there another way to fix this?
