斯威夫特的UITableViewController搜索錯誤 - [NSInternalInconsistencyException]

Question

我有使用SearchField，從一個簡單的數組搜索和過濾數據，然後爲用戶顯示過濾的數據點擊，但我發現這是造成錯誤與TableViewController的應用我的整個應用程序崩潰。

當我第一次運行應用程序時，我得到的最後擊殺前兩次警告當我鍵入一個字母進入搜索領域。這裏的每個實例的屏幕截圖，每個控制檯錯誤沿着我得到：

運行後：

而且這是我的SWIFT代碼：

import UIKit 

class SearchTableViewController: UITableViewController, UISearchResultsUpdating { 

let data = ["Aftershock","Asses","Apple","Alien"] 
var filteredData = [String]() 
var resultSearchController = UISearchController() 

override func viewDidLoad() { 
    super.viewDidLoad() 

    self.resultSearchController = UISearchController(searchResultsController: nil) 
    self.resultSearchController.searchResultsUpdater = self 
    self.resultSearchController.dimsBackgroundDuringPresentation = false 
    self.resultSearchController.searchBar.sizeToFit() 

    self.tableView.tableHeaderView = self.resultSearchController.searchBar 
    self.tableView.reloadData() 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 

override func numberOfSections(in tableView: UITableView) -> Int { 
    // #warning Incomplete implementation, return the number of sections 
    return 1 
} 

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    if (self.resultSearchController.isActive){ 
     return self.filteredData.count 
    }else{ 
     return 0 
    } 
} 

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 

    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as UITableViewCell? 

    // Configure the cell... 
    cell!.textLabel?.text = self.filteredData[indexPath.row] 
    return cell! 
} 

func updateSearchResults(for searchController: UISearchController) { 
    self.filteredData.removeAll(keepingCapacity: false) 

    let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!) 
    let array = (self.data as NSArray).filtered(using: searchPredicate) 
    self.filteredData = array as! [String] 

    self.tableView.reloadData() 
    } 
} 

老實說任何幫助將是金對我來說，因爲它的殺了我！ 謝謝你的時間。

Answer 1

由於您使用的UITableViewCell.textLabel財產，我會假設你想使用UITableViewCell s的默認樣式之一。

你試圖調用tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)而沒有註冊的可重複使用的細胞有這樣的標識符。您的代碼在viewDidLoad中缺少對tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")的呼叫。
