我正在制作闪存卡应用。现在我正在尝试为应用程序创建设置页面。我正在使用分割视图控制器,它将显示所有不同的单词组,每个组都有一个开关开关
如您所见,有11个不同的单词组。当我单击单词组时,我希望它显示拆分视图控制器右侧该组中的所有单词。在上图中,您可以看到第一组中包含的单词,但它们都显示在一行中。这就是我想为此使用表视图的原因。这是我遇到麻烦的地方。我不确定如何去做这件事。
对于我的Split视图控制器,我让它运行3个不同的文件 第一个文件是MasterViewController,我将发布下面的代码
import UIKit
protocol WordSelectionDelegate: class {
func wordSelected(newWord: Word)
}
class MasterViewController: UITableViewController {
var words = [Word]()
weak var delegate: WordSelectionDelegate?
override func viewDidLoad() {
super.viewDidLoad()
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
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: ""))
self.words.append(Word(name: "intersyllabic /l/", description: ""))
self.words.append(Word(name: "final /l/", description: ""))
self.words.append(Word(name: "initial /pl/", description: ""))
self.words.append(Word(name: "initial /bl/", description: ""))
self.words.append(Word(name: "initial /fl/", description: ""))
self.words.append(Word(name: "initial /gl/", description: ""))
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: ""))
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return self.words.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
// Configure the cell...
let word = self.words[indexPath.row]
cell.textLabel?.text = word.name
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt
indexPath: IndexPath) {
let selectedMonster = self.words[indexPath.row]
self.delegate?.wordSelected(newWord: selectedMonster)
if let Detail = self.delegate as? Detail {
splitViewController?.showDetailViewController(Detail, sender: nil)
}
}
}
接下来我有我的详细信息类,只要在分割视图控制器的左侧按下按钮,就会刷新UI。
import UIKit
class Detail: UIViewController {
@IBOutlet weak var descriptionLabel: UILabel!
var word: Word! {
didSet (newWord) {
self.refreshUI()
}
}
func refreshUI() {
descriptionLabel?.text = word.description
}
override func viewDidLoad() {
super.viewDidLoad()
refreshUI()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
extension Detail: WordSelectionDelegate {
func wordSelected(newWord: Word) {
word = newWord
}
}
最后,我有一个文件,为每个" word"提供特征。
import UIKit
class Word {
let name: String
let description: String
init(name: String, description: String) {
self.name = name
self.description = description
}
}
