3D Touch Quick actions根本不起作用
3D Touch Quick actions根本不起作用
提问于 2019-10-19 04:55:32
我已经检查了所有其他问题，但我找不出哪里出了问题。我从苹果开发人员网站Add Home Screen Quick Actions下载了示例项目，没有问题，但是当我开始一个新的Xcode项目并复制它时，它对我不起作用。我一定是漏掉了什么。在这一点上，我只想让它在控制台上打印出“快捷键按下”。当我将print("Shortcut pressed")添加到我下载的苹果项目中时，它工作得很好。
在这一点上，我只是在尝试一些随机的东西。
我用一个数组、一个字典和字符串更新了我的info.plist，我只是复制并传递了这些值，以免出现任何打字错误。
UIApplicationShortcutItems，项目0，UIApplicationShortcutItemType，UIApplicationShortcutItemIconType，UIApplicationShortcutItemTitle
按下应用程序图标时会出现快捷方式，但它只会打开应用程序。
这是我最基本的AppDelegate.Swift文件，只是试图让它做任何事情它可能是我的项目设置，我的Xcode版本是最新的-版本11.1 (11A1027)
我以前从来没有使用过Quick actions，它看起来很简单，但看起来很简单，只需在plist中添加一些行，并在AppDelegate.Swift文件中添加一些代码，但要花很长时间才能开始工作。
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var shortcutItemToProcess: UIApplicationShortcutItem?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
if let shortcutItem = launchOptions?[UIApplication.LaunchOptionsKey.shortcutItem] as? UIApplicationShortcutItem {
shortcutItemToProcess = shortcutItem
print("Shortcut pressed")
}
return true
}
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: (Bool) -> Void) {
print("Shortcut pressed")
}
func applicationDidBecomeActive(_ application: UIApplication) {
print("Shortcut pressed")
}
// MARK: UISceneSession Lifecycle
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
}谢谢你。

看起来你的应用是基于场景的。对于基于场景的应用程序，你几乎可以忘记AppDelegate，专注于SceneDelegate。现在有两个方法需要在SceneDelegate中覆盖，另一个方法需要在AppDelegate中覆盖。为了清楚起见，我将模仿苹果的指南：
如果用户正在打开应用程序，并且是新启动的应用程序，您可以在AppDelegate中处理此问题
// AppDelegate.swift
func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration {
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
// Grab a reference to the shortcutItem to use in the scene
if let shortcutItem = options.shortcutItem {
shortcutItemToProcess = shortcutItem
}
// Previously this method only contained the line below, where the scene is configured
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}如果当用户单击快捷方式项目时，您的应用程序仍在后台运行，则需要在SceneDelegate中进行处理
// SceneDelegate.swift
func windowScene(_ windowScene: UIWindowScene, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
// When the user opens the app through a quick action, this is now the method that will be called
(UIApplication.shared.delegate as! AppDelegate).shortcutItemToProcess = shortcutItem
}场景准备就绪后，您可以使用快捷键执行所需的操作：
// SceneDelegate.swift
func sceneDidBecomeActive(_ scene: UIScene) {
// Is there a shortcut item that has not yet been processed?
if let shortcutItem = (UIApplication.shared.delegate as! AppDelegate).shortcutItemToProcess {
// In this sample an alert is being shown to indicate that the action has been triggered,
// but in real code the functionality for the quick action would be triggered.
var message = "\(shortcutItem.type) triggered"
if let name = shortcutItem.userInfo?["Name"] {
message += " for \(name)"
}
let alertController = UIAlertController(title: "Quick Action", message: message, preferredStyle: .alert)
alertController.addAction(UIAlertAction(title: "Close", style: .default, handler: nil))
window?.rootViewController?.present(alertController, animated: true, completion: nil)
// Reset the shorcut item so it's never processed twice.
(UIApplication.shared.delegate as! AppDelegate).shortcutItemToProcess = nil
}
