Question

我正在制作我的第一个应用程序。现在我正在尝试制作设置页面。到目前为止它看起来像这样。

我将拆分视图控制器连接到主视图控制器和详细视图控制器（下面的代码）。如您所见，现在分割视图控制器左侧有一个包含不同按钮的表格视图。按下每个按钮时，我希望它在视图控制器的右侧显示一个单词列表。它确实显示了一个单词列表，但我想让它在表格视图中显示水平堆叠的单词，我不知道该怎么做。

    self.words.append(Word(name: "initial /l/ 1 syllable", description: "lake lamb lamp lark leaf leash left leg lime lion lips list lock log look love lunch"))

    self.words.append(Word(name: "initial /l/ multisyllabic", description: "words, words, words, words"))

    self.words.append(Word(name: "intersyllabic /l/", description: "words, words, words, words"))

    self.words.append(Word(name: "final /l/", description: "words, words, words, words"))

    self.words.append(Word(name: "initial /pl/", description: "words, words, words, words"))

    self.words.append(Word(name: "initial /bl/", description: "words, words, words, words"))

    self.words.append(Word(name: "initial /fl/", description: ""))

    self.words.append(Word(name: "initial /gl/", description: "words, words, words, words"))

    self.words.append(Word(name: "initial /kl/", description: ""))

    self.words.append(Word(name: "initial /sl/", description: ""))

    self.words.append(Word(name: "final /l/ clusters", description: ""))

class Word {
let name: String
let description: String




init(name: String, description: String) {
    self.name = name
    self.description = description


}
}

import UIKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    let splitViewController = self.window!.rootViewController as! UISplitViewController
    let leftNavController = splitViewController.viewControllers.first as! UINavigationController
    let MasterViewController = leftNavController.topViewController as! MasterViewController
    let Detail = splitViewController.viewControllers.last as! Detail

    let firstWord = MasterViewController.words.first
    Detail.word = firstWord

    MasterViewController.delegate = Detail

    return true
}

PS。如果您查看MasterViewController代码，您将看到它所说的位置＆＃34; description＆＃34;。描述中包含的列表应该显示在右侧的表格视图中。

在masterviewcontroller的func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)中，您需要更换viewcontroller。从appdelegate中获取splitviewcontroller实例，现在为splitview controllers的view controller属性分配了所需的viewcontroller对象，并确保所需的view controller对象具有导航控制器。

  override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    if indexPath.row == 1 {
        let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
        let splitViewController = appDelegate.window!.rootViewController as! UISplitViewController
        let nextViewController = storyBoard.instantiateViewController(withIdentifier: "yourviewcontrollername") as! UINavigationController
        splitViewController.viewControllers[1] = nextViewController
    }

将表视图添加到详细视图控制器
