比较值并在 uitableview 中显示特定结果

Question

我正在尝试将搜索过滤器添加到我的UITableView，当用户单击它时，我在导航栏“搜索”上有一个按钮，它会打开一个 xib 控制器，用户可以在完成后填写字段UITableView 应该只显示用户输入的比较结果。我已将 xib 中的所有值传递给 tableviewcontroller，但如何比较它们并显示具体结果？

var pj = [PostedJobs]()
var pjJobs = PostedJobs()

class FeaturedTableViewController: UITableViewController {

    @IBAction func btnSearch(sender: UIBarButtonItem) {

        let detailViewController:SearchViewController = SearchViewController(nibName: "SearchViewController", bundle: nil)

        self.presentPopupViewController(detailViewController, animationType: MJPopupViewAnimationFade)
        // detailViewController.detailViewController1 = self

    }
    @IBOutlet var myTableView: UITableView!
    @IBOutlet weak var menuButton: UIBarButtonItem!

    override func viewDidLoad() {
        super.viewDidLoad()

        println(sf.price)
        println(sf.deliveryTime)
        println(sf.distance)
        println(sf.featuredFilter)
        println(sf.location)
        println(sf.size)

        NSNotificationCenter.defaultCenter().addObserver(self, selector: "dismiss:", name:"dismiss", object: nil)

        if self.revealViewController() != nil {
            menuButton.target = self.revealViewController()
            menuButton.action = "revealToggle:"

            self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
        }

        alert.addButtonWithTitle("okay")

        request(.POST, urlString)

这是我的第一个应用程序，很抱歉代码混乱，有人可以帮忙吗？

Answer 1

您需要使用传递给UIViewController 的过滤数据来过滤您的原始数组。

//as in your code pj is the full array
// definde a new array to be the dataSource
var dataSource:[PostedJobs]!

假设您有一个方法，当用户完成过滤并返回表时将调用该方法，称为filterDate

func filterData() {
    let price = // the filtered price
    let loacation = // the filtered location
    let distance = // the filtered one
    let size = // the filtered one
    let time = // the filtered one
    let isFeatured = // the filtered one

   dataSource = jp.filter {
   $0.price == price && $0.location == location && $0.distance == distance &&  $0.size == size && $0.time.compare(time) == NSComparisonResult.OrderedSame && $0.isFeatured == isFeatured
  }
  // reload table 
  tableView.relaodData()

您将在所有UITableViewDataSourceDelegate 方法中使用dataSource 而不是pj。

Answer 2

不要使用pj 作为表格视图的来源。使用其他数组，当用户点击“完成”按钮时，循环遍历pj 数组并仅将应该在表视图中的内容添加到第二个数组。然后将其用作表格视图的来源。
