Swift 中 UISearchController 的链接数组

Question

我正在使用 UISearchController 让用户搜索我的数据（这些来自 XML 并被解析为数组），现在我想在我的 Cell 中添加多个 UILabel，但这些 UILabel 信息来自不同的数组。

当我更新搜索时，2. 数组的排序方式与第一个不同。

AP = ["FIRST1","FIRST2","FIRST3","FIRST4","FIRST5"]
APSecound = ["SEC1","SEC2","SEC3","SEC4","SEC5"]
var filteredTableDataAP = [String]()
var filteredTableDataAPSecound = [String]()


func updateSearchResultsForSearchController(searchController: UISearchController)
{
    filteredTableDataIcao.removeAll(keepCapacity: false)

    let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!)
    let array = (AP as NSArray).filteredArrayUsingPredicate(searchPredicate)
    filteredTableDataAP = array as! [String]
    //i think here i some how could set index of "filteredTableDataAP = filteredTableDataAPSecound" so they been filtered like the same shema



    self.tableView.reloadData()
}


Override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("CustomTableViewCellSearch", forIndexPath: indexPath) as! CustomTableViewCellSearch


    if (self.resultSearchController.active) {
        cell.APLB.text = filteredTableDataAP[indexPath.row]
        cell.APSecoundLB.text = filteredTableDataAPSecound[indexPath.row]

        return cell
    }
    else {
        cell.APLB.text = AP[indexPath.row]
        cell.APSecoundLB.text = APSecound[indexPath.row]

        return cell
    }
}

第一次运行时不搜索单元格看起来很好

(FIRST1)(SEC1)
(FIRST2)(SEC2)
(FIRST3)(SEC3)
(FIRST4)(SEC4)

但是一旦我搜索“4”，单元格看起来像

(FIRST4)(SEC1)

有什么简单的方法可以“保持第二个数组的位置像第一个数组一样”

Answer 1

我使用的方式如下

你有两个数组：

        AP = ["FIRST1","FIRST2","FIRST3","FIRST4","FIRST5"]
        APSecound = ["SEC1","SEC2","SEC3","SEC4","SEC5"]
        var getIndex = 0

        if (self.SearchController.active) // check if SearchController isactive
        {

            //This will get the index of main array
             getIndex = AP.indexOf(filteredsearchPost[indexPath.row])! 
            //According to example index should be 1 for "FIRST2"


    .      cell.APSecoundLB.text = APSecound[getIndex] 
//set it with the retrived index and its done
//it will print "SEC2"


        }else {
           getIndex = indexPath.row
          cell.APLB.text = AP[getIndex]
          cell.APSecoundLB.text = APSecound[getIndex]
          //Do the else part here
      }

Answer 2

你刚刚过滤了AP 没有过滤APSecound

 let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!)
 let array = (AP as NSArray).filteredArrayUsingPredicate(searchPredicate)
 let arraySecond = (APSecound as NSArray).filteredArrayUsingPredicate(searchPredicate)

 filteredTableDataAP = array as! [String]
filteredTableDataAPSecound = arraySecond as! [String]

或者你可以使用filteredResault: [[String: String?]]，[String: String?]是Dictionary，filteredResault是Dictionary array。像["AP": "FIRST1", "APSecound": "SEC1"]这样的字典
