Swift-Add disclosure indicator to a UITableViewCell
提问by Motoko
I'm new to iOS. I had 2 Table View Controllers and I want user to click on 1 cell to navigate to the other Controllers.
我是 iOS 新手。我有 2 个表视图控制器，我希望用户单击 1 个单元格以导航到其他控制器。
However here you can see the sign ">" next to the item, same as in Settings app in iOS 8. https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewAndDataModel/TableViewAndDataModel.html
但是，在这里您可以看到项目旁边的符号“>”，与 iOS 8 中的“设置”应用程序相同 。https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewAndDataModel/TableViewAndDataModel。 html
But I cannot add Navigation Item to a cell and no matter what segue I use the '>' doesn't show up.
但是我无法将导航项添加到单元格中，无论我使用什么 segue，“>”都不会显示。
Any idea?
任何的想法？

First things first. If you need navigation between view controllers, you need to embed the first view controller in a navigation controller. Each navigation controller maintains a stack on which you can push view controllers. Please refer to the navigation controller documentation. If you want the '>' show up by default, goto the storyboard, click on the cell, goto the fourth tab on the right hand side, select the accessory as 'Disclosure Indicator'.
先说第一件事。如果需要在视图控制器之间进行导航，则需要将第一个视图控制器嵌入到导航控制器中。每个导航控制器维护一个堆栈，您可以在其中推送视图控制器。请参阅导航控制器文档。如果您希望默认显示“>”，请转到情节提要，单击单元格，转到右侧的第四个选项卡，选择附件作为“披露指示器”。

That arrow isn't a UINavigationItem; it's a UITableViewCellAccessoryDisclosureIndicator.
那个箭头不是UINavigationItem; 这是一个UITableViewCellAccessoryDisclosureIndicator.
To add that UITableViewCellAccessoryDisclosureIndicator"arrow" to your cell's accessory view, add this line:
要将UITableViewCellAccessoryDisclosureIndicator“箭头”添加到单元格的附件视图中，请添加以下行：
cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
And then to perform a specific action when that accessory view is tapped, implement tableView:accessoryButtonTappedForRowWithIndexPath:.
然后要在点击该附件视图时执行特定操作，请实现tableView:accessoryButtonTappedForRowWithIndexPath:.

In Swift 4 and Swift 5 this would be:
在 Swift 4 和 Swift 5 中，这将是：
cell.accessoryType = .disclosureIndicator
You can also set it in IB if appropriate: Attributes Inspector > Table View Cell > Accessory.
如果合适，您也可以在 IB 中设置它：属性检查器 > 表格视图单元格 > 附件。
