如何在tableview swift中显示复选标记? [英] How to show Checkmark in tableview swift?

问题描述

在选择某些数组值之前，我必须显示复选标记，我必须显示数组值 1 的复选标记，而 0 则不显示复选标记.如何做到这一点..检查下面的代码:

I have to show check mark before i selected for some array values, i have to show the checkmark for array value 1 and none for 0.How to do that..check the code below:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{

    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
    cell.textLabel?.text = AllItems[indexPath.row] as? String
    for dict1  in selectedItems
    {
         if Intvalues == dict1 as? NSObject  {
           // I have to show CheckMark
}
          else if ZeroIntvalues == dict1 as? NSObject
         {
            // I don’t need to show CheckMark



        }
    }
    cell.textLabel?.textColor = UIColor.whiteColor()
    return cell
}

推荐答案

因为@Paulw11 说的原因，你的代码是错误的.由于for循环的最后一个对象总是1.

Because of reason @Paulw11 said, your code is wrong. Each tableViewCell is displayed checkmark because the last object of for loop is always 1.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
    cell.textLabel?.text = AllItems[indexPath.row] as? String
        if Intvalues == AllItems[indexPath.row] as? Int  {
           // I have to show CheckMark
          cell.accessoryType = .Checkmark
         } else {
          cell.accessoryType = .None
         }
    cell.textLabel?.textColor = UIColor.whiteColor()
    return cell
}
