解析Swift UITableView附件

Question

我有下面的代碼，現在我試圖實現UITableView的附件。 所有的數據都來自Parse，即使有幫助瞭解如何執行常規配件的教程，但我無法找到一個實際教導如何從Parse等在線數據庫獲取數據的人。

class Listdoctors: UITableViewController { 

    @IBOutlet var listdoctors: UITableView! 


    var doctorName = [String]() 
    var doctorRate = [NSInteger]() 
    var doctorDetail = [String]() 


    var refresher: UIRefreshControl! 




    func refresh() 
    { 
     let query = PFQuery(className: "doctors") 
     query.orderByDescending("createdAt") 

     query.findObjectsInBackgroundWithBlock(

      { 
       (listll: [PFObject]?, error: NSError?) -> Void in 

       if error == nil { 
        // The find succeeded. 
        print("Successfully retrieved \(listll!.count) names of the lawyers.") 
        // Do something with the found objects 
        if let objects = listll { 
         for object in objects { 
          print(object) 

          self.doctorName.append(object["doctorName"] as! String) 
          self.doctorRate.append(object["Rate"] as! NSInteger) 
          self.doctorDetail.append(object["doctorContent"] as! String)

我的代碼，最後一行是不是我知道我究竟需要返回，這是我從 https://www.youtube.com/watch?v=c-E_EbMR9wA

從外觀上來看下面一個例子，你想將你的數據傳遞給一個細節視圖，在這種情況下，你應該這樣做，假設你已經在detailView中定義了正確的indexPath和變量。

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
      if let identifier = segue.identifier 
      { 
       switch identifier 
       { 
        doctor "TodoctorDetail": 
         let productDetailVC = segue.destinationViewController as! doctorDetail 
        if let indexPath = self.tableView.indexPathForCell(sender as! UITableViewCell) 
        { 
         // Assuming you have the proper indexPath defined here for the selected cell and that you have these three values already defined in your productDetailVC 
         productDetailVC.doctorName = doctorName[indexPath.row] 
         productDetailVC.doctorContent = doctorContent[indexPath.row] 
         productDetailVC.doctorRate = doctorRating[indexPath.row] 
        } 


       default: break 
       } 
      }ˍ 
     }
