我想为icarousel设置属性以获得此形状

我有这个代码设置它，但结果不是100%正确

  CGFloat count = [self circularCarouselItemCount];
        CGFloat spacing = [self valueForOption:iCarouselOptionSpacing withDefault:2.5];
        CGFloat arc = [self valueForOption:iCarouselOptionArc withDefault:M_PI * 1.0];
        CGFloat radius = [self valueForOption:iCarouselOptionRadius withDefault:MAX(_itemWidth * spacing / 2.0, _itemWidth * spacing / 2.0 / tanf(arc/2.0/count))];
        CGFloat angle = [self valueForOption:iCarouselOptionAngle withDefault:offset / count * arc];

结果看起来像
