ios - 如何制作如下所示的书籍封面阴影

Question

我需要右左和下阴影UIImageView不低于尝试下面的阴影代码但没有按预期工作

viewCheck.layer.shadowRadius  = 1.5f;
viewCheck.layer.shadowColor   = [UIColor colorWithRed:176.f/255.f green:199.f/255.f blue:226.f/255.f alpha:1.f].CGColor;
viewCheck.layer.shadowOffset  = CGSizeMake(0.0f, 0.0f);
viewCheck.layer.shadowOpacity = 0.9f;
viewCheck.layer.masksToBounds = NO;

UIEdgeInsets shadowInsets     = UIEdgeInsetsMake(0, 0, -1.5f, 0);
UIBezierPath *shadowPath      = [UIBezierPath 
bezierPathWithRect:UIEdgeInsetsInsetRect(viewCheck.bounds, shadowInsets)];
viewCheck.layer.shadowPath    = shadowPath.CGPath;
