swift - 无法为 '[String]' 类型的值添加下标

Question

我在 if 语句中收到错误消息

if (SelectedJobFunctions.contains(JobFunctions[indexPath.row])){
            cell.accessoryType = .Checkmark
        }
        else {
            cell.accessoryType = .None
        }

这是数组

var JobFunctions = ["Cleaning","Admin","Slacking","Business"]
var SelectedJobFunctions = [] 

我试图查看用户是否选择了一个函数，如果它已被选择，将在 SelectedJobFunctions 数组中，它会添加一个复选标记

Answer 1

尝试在 SelectedJobFunctions 中指定数组类型，如下所示

   var JobFunctions = ["Cleaning","Admin","Slacking","Business"]
   var SelectedJobFunctions:[String] = []
   if (SelectedJobFunctions.contains(JobFunctions[indexPath.row])){
               cell.accessoryType = .Checkmark
   }
   else {
              cell.accessoryType = .None
   }
