致命错误：数组索引超出范围与Parse.com

Question

我有夫特2和Parse.com的应用程序。我添加了UISearchController，当我使用它时，应用程序崩溃。它显示了一个错误"fatal error: Array index out of range"。

有串"if var pfFiltered = dataForSearchController?[indexPath.row]" is EXC_BAD_INSTRUCTION一个错误，当我在搜索栏中触摸。

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject?) -> PFTableViewCell? { 
    var searchText = searchController.searchBar.text 

    let cellIndentifier: String = "NewsCell" 

    var cell: ParseTableViewCell? = tableView.dequeueReusableCellWithIdentifier(cellIndentifier) as? ParseTableViewCell 

    if searchController.active == false { 
     if (cell == nil) { 
      cell = ParseTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: cellIndentifier) 
     } 

     if let pfObject = object { 
      //cell?.textLabel?.text = pfObject["textNews"] as? String 
      cell?.labelNameText?.text = pfObject["nameNews"] as? String // name 
      cell?.labelDataText?.text = pfObject["dateNews"] as? String // data 
      cell?.labelText = pfObject["textNews"] as? String 
      cell?.labelURLNews = pfObject["urlNews"] as? String // link on a site with news 

      var imageFromParse = object?.objectForKey("imageNews") as? PFFile 
      imageFromParse?.getDataInBackgroundWithBlock({ (imageData: NSData?, error: NSError?) -> Void in 
       var image: UIImage! = UIImage(data: imageData!)! 
       cell?.imageViewCell.image = image 
      }) 
     } 
    } else { 
     if var pfFiltered = dataForSearchController?[indexPath.row] { 
      cell?.labelNameText?.text = pfFiltered["nameNews"] as? String 
      cell?.labelDataText?.text = pfFiltered["dateNews"] as? String 
      cell?.labelText = pfFiltered["textNews"] as? String 
      cell?.labelURLNews = pfFiltered["urlNews"] as? String 

      var imageFromFilteredParse = object?.objectForKey("imageNews") as? PFFile 
      imageFromFilteredParse?.getDataInBackgroundWithBlock({ (imageDataTwo: NSData?, error: NSError?) -> Void in 
       var imageTwo: UIImage = UIImage(data: imageDataTwo!)! 
       cell?.imageViewCell.image = imageTwo 
      }) 
     } 
    } 
    return cell 
}

override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    return 1 
} 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    var query: PFQuery = PFQuery(className: "NewsNow") 
    if self.dataForSearchController == nil { 
     return objects?.count ?? 0 
    } else { 
     return dataForSearchController?.count ?? 0 
    } 
}
