SWIFT UITableView - 在原型单元格中的多行继续到另一个UITableView

我真的不知道要搜索什么关于这个问题，我的搜索尝试没有太多的帮助，所以我想我会给这个帖子一个镜头。SWIFT UITableView - 在原型单元格中的多行继续到另一个UITableView

我有一个将有三个行的原型单元格。我想要发生的事情是从每行显示另一个UITableView的segue - 但我希望保持视图控制器的数量最小，所以我希望这可以实现只有一个tableViewController。

例如，第1行是“外径（OD）”，第2行是“重量”，第3行是“内径（ID）”。这些被定义为TableViewController文件的类声明下的常量。

我有一个从上述TableViewController的segue（Modally）到第二个TableViewController，为此我为它创建了一个新文件。我在我的类声明下定义了这个文件中的OD，Weight和ID值作为常量。

有没有什么办法可以达到这个目的，当用户点击OD行时，它只会显示我在第二个视图控制器中为OD定义的值/常量，以及仅显示何时的Weight和ID常量用户分别点击这些行？我的困惑是如何链接两个TableViewControllers，以便它们可以互相交互...但我不确定这是否是所有可能的。我的代码迄今如下：

表视图控制器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并声明如下

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() 
    } 
}

现在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 
} 
}

感谢您的回复！我会在下班回家时给你一个镜头，让你知道它是怎么回事 – Matty

当我在我的viewDidLoad中输入开关盒时，它给了我一个错误“enum case'OuterDiameter'在数据类型中找不到！”。。这可以完全相关的事实，我使用tableViewController而不是使用tableView顶部的viewController？ – Matty

这一切是不是complex.Do以下。

在首先的viewController如你说“我有从上述TableViewController一个赛格瑞（模态）向第二TableViewController”给这个原因请看的标识符。
在第二个ViewController上为第一个viewncontroller中选择的行的类型添加一个类似当前选择的属性。
在第一次的viewController在你didselectrow方法设置当前选择到一个变量，然后执行

（无效）prepareForSegue：（UIStoryboardSegue *）赛格瑞发件人：（ID）发送

这里从segue获取您的视图控制器并将属性设置为当前选择
在您的secondViewController的ViewWillAppear或任何其他适当的方法根据您当前选择的属性加载数据。

谢谢伊姆兰的回答。我有一个问题是你是什么意思，通过添加一个属性，如当前选择的行在我的第一个视图控制器中选择的行类型？ – Matty

是的，可以是字符串或枚举或任何你喜欢的 – Imran

嗨伊姆兰，我相信你说的是可爱的天使在他们对这篇文章的回答中提到的。然而，我不能让开关工作......得到错误“enum case'OuterDiameter'没有在数据类型中找到！”。有什么建议么？ – Matty

斯威夫特版本。

您可以添加标签，你的自定义单元格按钮（你的子类它，给它标识符，并且如果它是一个笔尖你注册的子类？），然后在的cellForRowAtIndexPath -

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

谢谢Elkhan，当我在我的单元中有一个按钮的阶段时，它会派上用场！ – Matty
