我正在使用SplitViewController中的字典应用程序。在主视图控制器上,我想显示各种输入单词及其被点击的次数,而在细节上,我想要显示单词的定义和细节。到目前为止,我已经完成了所有设置,但要敲击单词的次数应该显示在主视图控制器上。如何在主视图控制器中自定义各种标签并添加标签?
// "Word" class
import UIKit
class Word {
let name: String
let meaning: String
let wordType: String
let numberOfTimesFound: String
init(name: String, meaning: String, wordtype: String, numberOfTimesFound: String) {
self.name = name
self.meaning = meaning
self.wordType = wordtype
self.numberOfTimesFound = numberOfTimesFound
}
}
let words = [
Word(name: "Afraid", meaning: "WORD DEFINITION GOES HERE", wordtype: "adjective", numberOfTimesFound: "1")
]
//MasterViewController.swift
import UIKit
class MasterViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
let firstWord = words.first
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return words.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let word = words[indexPath.row]
cell.textLabel?.text = word.name
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let word = words[indexPath.row]
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.detailViewController.refreshUI(word: word)
}
//AppDelegate.swift
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var masterViewController = MasterViewController()
var detailViewController = DetailViewController()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
let splitViewController = window?.rootViewController as? UISplitViewController
let leftNavController = splitViewController!.viewControllers.first as? UINavigationController
masterViewController = (leftNavController?.topViewController as? MasterViewController)!
detailViewController = (splitViewController!.viewControllers.last as? DetailViewController)!
// Override point for customization after application launch.
return true
}
最佳答案
在项目导航器中选择情节提要或笔尖。
选择原型单元。
按⌥⌘4以显示“属性”检查器。
将单元格的style
设置为Right Detail
,Left Detail
或Subtitle
,这将启用detailTextLabel
标签。
在cellForRowAt
中,将第二个字符串分配给text
的detailTextLabel
属性。
如果预定义的样式无法满足您的需要,请将样式设置为custom
,将所有UI元素拖到单元格,添加约束,创建UITableViewCell
子类,添加IBOutlets
,连接插座,设置样式。单元格转换为自定义类,并将cellForRowAt
中出队的单元格转换为自定义类。
