ios - UISearchBar 未更新

Question

我有一个 UIViewController，我在其中添加了 UITableViewController，并且我以编程方式添加搜索栏。我可以在控制台上搜索后打印结果，但是当我单击搜索栏时，自定义表格单元格仍然会填充，并且搜索根本不会更新它们。

我在 override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell 中有打印语句来检查搜索 Controller 是否处于事件状态，并且它从不打印该语句。

import UIKit
import Parse

class MasterViewController: UITableViewController, UISearchResultsUpdating, UISearchBarDelegate {

@IBOutlet var mTableView: UITableView!
var detailViewController: DetailViewController? = nil
var objects = [AnyObject]()
var resultSearchController = UISearchController()
var filteredData : NSMutableArray = []
var sectionInTable : NSMutableArray = ["Grand Haven 9", "Holland 7"]
var movieTitle : NSMutableArray = ["The Hunger Game 2","Creed"]
var movieTimeSection1 : NSMutableArray = ["11:00am, 11:40, 12:10pm, 1:25, 2:30, 6:05, 6:55, 7:30, 9:05", "11:10am, 11:50, 12:20pm, 2:25, 3:30, 6:05, 6:55, 8:30, 10:05"]
var movieTimeSection2 = ["Title": "Martian", "Theatre": "Holland 7", "Time": "11:00am, 11:40, 12:10pm, 1:25, 2:30, 6:05, 6:55, 7:30, 9:05"]


var onlineMovieTitle : NSMutableArray = []

var movieSection1 : NSMutableArray = []
var movieSection2 : NSMutableArray = []

override func viewDidLoad() {
    super.viewDidLoad()

    print(movieSection1)
    print(movieSection2)

    self.tableView.separatorColor = UIColor.cloudsColor()

        controller.searchResultsUpdater = self
        controller.dimsBackgroundDuringPresentation = false
        controller.searchBar.delegate = self
        controller.searchBar.sizeToFit()
        controller.preferredStatusBarStyle() == UIStatusBarStyle.LightContent
        controller.hidesNavigationBarDuringPresentation = false
        self.mTableView.tableHeaderView = controller.searchBar

        return controller
    })()
    //self.resultSearchController.searchBar.endEditing(true)

}
func updateSearchResultsForSearchController(searchController: UISearchController){
    filteredData.removeAllObjects()

    let searchPredicate = NSPredicate(format: "Title CONTAINS %@", searchController.searchBar.text!.uppercaseString)
    let array = (movieSection1 as NSArray).filteredArrayUsingPredicate(searchPredicate)
    let array2 = (movieSection2 as NSArray).filteredArrayUsingPredicate(searchPredicate)
    //let array2 = (movieTimeSection1 as NSArray).filteredArrayUsingPredicate(searchPredicate)
    filteredData.addObjectsFromArray(array)
    filteredData.addObjectsFromArray(array2)

    print(filteredData)
}

    super.viewWillAppear(animated)
    self.resultSearchController.searchBar.hidden = false
}

任何帮助将不胜感激。谢谢

我错过了它，感谢 Larcerax，通过添加 mTableView.reloadData()
