objective-c - 删除分组的 UITableView 中的顶部阴影？

Question

我有点强制症，这让我发疯。我已经弄乱这些设置很长时间了。

我有一个 UITableView 分组，顶部有一个阴影。当您点击顶部的单元格时，它会移除。给了什么？

在过去的一个多小时里，我一直在为此强调。有一个简单的解决方案吗？还是我要疯了？

谢谢，库尔顿

编辑:

viewDidLoad:

formTableView.backgroundColor = [UIColor clearColor];
formTableView.layer.borderColor = [UIColor clearColor].CGColor;
formTableView.separatorColor = [UIColor colorWithRed:(194.0 / 255.0) green:(194.0 / 255.0) blue:(194.0 / 255.0) alpha: 1];

这是我显示单元格的方式。 警告:这是很多代码。里面有一堆东西你必须整理，所以整理它需要你自担风险! :)

将表格 View 的分隔符样式设置为 UITableViewCellSeparatorStyleSingleLine。它目前被设置为 UITableViewCellSeparatorStyleSingleLineEtched，这在 iPhone 上产生了双顶边框的效果(它在 iOS 5 以及 iPad 上的 iOS 3.2 和 4 上看起来更详细)。
