Implement TableView single selection

Import UIKit

Class Viewcontroller:uiviewcontroller {

var tableview:uitableview!

Override Func Viewdidload () {

Super.viewdidload ()

TableView = UITableView (frame:cgrectmake (0, 0, Uiscreen.mainscreen (). Bounds.width, Uiscreen.mainscreen (). Bounds.height), style:. Plain)

Tableview.delegate = Self

Tableview.datasource = Self

Self.view.addSubview (TableView)

}

}

Extension Viewcontroller:uitableviewdatasource,uitableviewdelegate {

Func TableView (Tableview:uitableview, Numberofrowsinsection section:int), Int {

return 20

}

Func TableView (Tableview:uitableview, Cellforrowatindexpath indexpath:nsindexpath), UITableViewCell {

Let cell = UITableViewCell (style:. Default, Reuseidentifier: "Cell")

Cell.textlabel?. Text = "123"

return cell

}

Gets the path of the cell that will be selected

Func TableView (Tableview:uitableview, Didselectrowatindexpath Indexpath:nsindexpath) {

Uncheck the Style

Tableview.deselectrowatindexpath (Indexpath, Animated:true)

Gets the currently selected cell

Let cell:uitableviewcell! = Tableview.cellforrowatindexpath (Indexpath)

Return all cells

Traversal cancels all cell styles

var Arry = Tableview.visiblecells

For i in 0.. < Arry.count {

Let Cells:uitableviewcell = Arry[i]

Cells.accessorytype =. None

}

Set the selected cell style

Cell.accessorytype =. Checkmark

}

}
