iOS 7 TableView就像iPad上的设置应用程序一样 [英] iOS 7 TableView like in Settings App on iPad
问题描述
我想要一个具有相同风格的UITableView组,如 iOS 7 的iPad设置应用程序详细信息视图。
I want to have a group UITableView with the style same like the iPad Settings application Detail view for iOS 7.
这是一个带圆角的tableView。请查看附件以获取详细信息。
It is a tableView with rounded corner. Please check the attachment for details.
是否有一些默认设置使它看起来像这样或我们需要为它做一些自定义绘图。
Is some default settings to make it look like that or we need to do some custom drawing for the same.
任何正确方向的提示都将受到赞赏。
Any hint in right direction will be appreciated.
谢谢

推荐答案
我已经进一步定制了willDisplayCell,以便更好地模拟设置应用中的单元格样式。
I've gone ahead and further customized the willDisplayCell to get a better simulation of the cell styles in the settings app.
