SWIFT UITableView - 在原型单元格中的多行继续到另一个UITableView
问题描述：
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
}
}

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。

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)
+0
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
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
