ios - UITableView Selected Row Position keep stay

Question

我有 UITableViewController 和行列表，我将原型(prototype)单元连接到 NavigationController 并且它是 rootViewController，一切正常，但是一旦我选择像行 no:10 这样的行，它会进入其主细节 View ，当我单击返回按钮时，它会将我带回 UITableViewController 但这次 UITableViewController 滚动回顶部位置，它应该停留在 no:10 行，这是在我从详细 View 返回时保持我的行位置的方法吗？

swift 3，Xcode 8.2.1

class EventTableViewController: UITableViewController {

private let tableData:[Cell] = [
    Cell(
        image: "burj_k",
        title: "Hola",
        place: "DFX",
        date: "SDSDs"
    ),
    Cell(
        image: "burj_k",
        title: "Hola 1",
        place: "DFX",
        date: "SDSDs"
    ),
    Cell(
        image: "burj_k",
        title: "Hola 2",
        place: "DFX",
        date: "SDSDs"
    ),
    Cell(
        image: "burj_k",
        title: "Hola 3",
        place: "DFX",
        date: "SDSDs"
    ),
    Cell(

        date: "SDSDs"
    )
]



override func viewDidLoad() {
    super.viewDidLoad()
    //remembersLastFocusedIndexPath = true

    // Uncomment the following line to preserve selection between presentations
    // self.clearsSelectionOnViewWillAppear = false

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
}

你的结构有误，

有了这个结构，你就会有 iOS 自动返回按钮，否则你可以添加自己的，在这种情况下不需要创建 unwind segue 方法。

编辑:

如果你想要自己的后退按钮，那么你需要调用它的 Action ，

navigationController?.popViewController(animated: true)
