有人请解释如何创建一个或两个像素阴影只在最后一个单元格（换句话说，我不想在整个tableview，只是底部单元格的阴影。我在说：

Would somebody please explain how to create a one or two pixel drop shadow ONLY on the the very last cell (in other words, I don't want a shadow around the entire tableview, just the bottom cell. An image of what I'm talking about:

推荐答案

解决。使用下面的代码在 UITableViewCell 。使它看起来像是从页面中略微提升：）

Solved. Use the following code to produce a very nice, subtle shadow to the bottom of your UITableViewCell. Makes it look like it's raised slightly out of the page :)

UIView* separatorLineView = [[UIView alloc] initWithFrame:CGRectMake(3, 49, cell.frame.size.width-26, 3)];/// change size as you need.
        separatorLineView.backgroundColor = shadowColor;// you can also put image here
        UIBezierPath *roundedShadow = [UIBezierPath bezierPathWithRoundedRect:separatorLineView.bounds byRoundingCorners:UIRectCornerBottomLeft|UIRectCornerBottomRight cornerRadii:CGSizeMake(8.0f, 8.0f)];
        CAShapeLayer *newSeparatorShape = [[CAShapeLayer alloc] init];
         [newSeparatorShape setPath:roundedShadow.CGPath];

        separatorLineView.layer.mask = newSeparatorShape;

        [cell.contentView addSubview:separatorLineView];

此外，不要忘记将它放在.m文件的顶部 #import< QuartzCore / QuartzCore.h>

Also, don't forget to put this at the top of your .m file #import <QuartzCore/QuartzCore.h>
