SWIFT UITableView - 在原型單元格中的多行繼續到另一個UITableView

我真的不知道要搜索什麼關於這個問題，我的搜索嘗試沒有太多的幫助，所以我想我會給這個帖子一個鏡頭。SWIFT UITableView - 在原型單元格中的多行繼續到另一個UITableView

我有一個將有三個行的原型單元格。我想要發生的事情是從每行顯示另一個UITableView的segue - 但我希望保持視圖控制器的數量最小，所以我希望這可以實現只有一個tableViewController。

例如，第1行是「外徑（OD）」，第2行是「重量」，第3行是「內徑（ID）」。這些被定義爲TableViewController文件的類聲明下的常量。

我有一個從上述TableViewController的segue（Modally）到第二個TableViewController，爲此我爲它創建了一個新文件。我在我的類聲明下定義了這個文件中的OD，Weight和ID值作爲常量。

有沒有什麼辦法可以達到這個目的，當用戶點擊OD行時，它只會顯示我在第二個視圖控制器中爲OD定義的值/常量，以及僅顯示何時的Weight和ID常量用戶分別點擊這些行？我的困惑是如何鏈接兩個TableViewControllers，以便它們可以互相交互...但我不確定這是否是所有可能的。我的代碼迄今如下：

表視圖控制器1：

import UIKit 

class CapacitiesTableViewController: UITableViewController { 

let capacityParameters = ["O.D", "Weight", "I.D"] 

@IBAction func cancelSelection(segue: UIStoryboardSegue) { 

} 

override func viewDidLoad() { 
    super.viewDidLoad() 

    // Uncomment the following line to preserve selection between presentations 
    // self.clearsSelectionOnViewWillAppear = false 

    self.tableView.rowHeight = UITableViewAutomaticDimension 
    self.tableView.estimatedRowHeight = 125.0 
} 

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

// MARK: - Table view data source 

override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    // #warning Incomplete implementation, return the number of sections 
    return 2 
} 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

    if section == 0 { 
     return capacityParameters.count 
    } else { 
     return 1 
    } 

} 


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 

    // init return type of cell 
    var returnCell: UITableViewCell! 

    if indexPath.section == 0 { // you can also check for section with section.index 
     returnCell = tableView.dequeueReusableCellWithIdentifier("capacitiesCell", forIndexPath: indexPath) 

     let capacityID = capacityParameters[indexPath.row] 
     returnCell.textLabel?.text = capacityID 

    return returnCell 

    } else { 

     returnCell = tableView.dequeueReusableCellWithIdentifier("cell2", forIndexPath: indexPath) 

     return returnCell 

    } 
} 


override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? { 

    if section == 0 { 
     return "Casing Specification" 
    } else { 
     return "Dimension & Strength" 
    } 
}

首先去ViewController2.swift並聲明如下

enum Data 
{ 
    case OuterDiameter 
    case Weight 
    case Innerdiameter 
} 

class ViewController2: UIViewController, UITableViewDataSource, UITableViewDelegate { // Or sub class of UITableViewController 

    var selectedData:Data! 

    override func viewDidLoad() { 

    super.viewDidLoad() 
    switch self.selectedData { 
     case .OuterDiameter : 
      //arrData = fill outer data 
      break 
     case .Weight : 
      //arrData = fill weight 
      break 
     case .Innerdiameter : 
      //arrData = fill inner data 
      break 
    } 
    tblview.reloadData() 
    } 
}

現在ViewController1.swift

class ViewController1: UIViewController, UITableViewDataSource, UITableViewDelegate { // Or sub class of UITableViewController 

var selectedOption:Data! 

// ............ 

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 

    if indexPath.row == 0 { 
     selectedOption = Data.OuterDiameter 
    } 
    else if indexPath.row == 1 { 
     selectedOption == Data.Weight 
    } 
    else { 
     selectedOption = Data.Innerdiameter; 
    } 
    self.performSegueWithIdentifier("ViewController2", sender: nil) 
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    // Get the new view controller using segue.destinationViewController. 
    // Pass the selected object to the new view controller. 

    let view2 = segue.destinationViewController as! ViewController2 
    view2.selectedData = selectedOption 
} 
}

感謝您的回覆！我會在下班回家時給你一個鏡頭，讓你知道它是怎麼回事 – Matty

當我在我的viewDidLoad中輸入開關盒時，它給了我一個錯誤「enum case'OuterDiameter'在數據類型中找不到！」。。這可以完全相關的事實，我使用tableViewController而不是使用tableView頂部的viewController？ – Matty

這一切是不是complex.Do以下。

在首先的viewController如你說「我有從上述TableViewController一個賽格瑞（模態）向第二TableViewController」給這個原因請看的標識符。
在第二個ViewController上爲第一個viewncontroller中選擇的行的類型添加一個類似當前選擇的屬性。
在第一次的viewController在你didselectrow方法設置當前選擇到一個變量，然後執行

（無效）prepareForSegue：（UIStoryboardSegue *）賽格瑞發件人：（ID）發送

這裏從segue獲取您的視圖控制器並將屬性設置爲當前選擇
在您的secondViewController的ViewWillAppear或任何其他適當的方法根據您當前選擇的屬性加載數據。

謝謝伊姆蘭的回答。我有一個問題是你是什麼意思，通過添加一個屬性，如當前選擇的行在我的第一個視圖控制器中選擇的行類型？ – Matty

是的，可以是字符串或枚舉或任何你喜歡的 – Imran

嗨伊姆蘭，我相信你說的是可愛的天使在他們對這篇文章的回答中提到的。然而，我不能讓開關工作......得到錯誤「enum case'OuterDiameter'沒有在數據類型中找到！」。有什麼建議麼？ – Matty

斯威夫特版本。

您可以添加標籤，你的自定義單元格按鈕（你的子類它，給它標識符，並且如果它是一個筆尖你註冊的子類？），然後在的cellForRowAtIndexPath -

cell.youButton.tag = indexPath.row 
cell.youButton.addTarget(self, action: "youMethod", forControlEvents: .TouchDown)

謝謝Elkhan，當我在我的單元中有一個按鈕的階段時，它會派上用場！ – Matty
