UITableViewCells中的选中标记显示不正确

这样的事情会不适合你呢？我没有测试它,因为我不在我的Mac上.

var selectedCells = [NSIndexPath]()

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell")!
    cell.accessoryType = selectedCells.contains(indexPath) ? .Checkmark : .None

    return cell
}

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    let selectedCell = tableView.cellForRowAtIndexPath(indexPath)

    selectedCells.append(indexPath)

    if selectedCell?.accessoryType == .Checkmark {

        selectedCell?.accessoryType = .None

        selectedCells = selectedCells.filter {$0 != indexPath}

    } else {

        selectedCell?.accessoryType = .Checkmark
    }
}
