我正在尝试实现一个 3D 触摸命令,如果用户按下“新扫描”,则ProcessedImageViewController
调用视图控制器。我已经设置了创建快速选项,但是当按下“新扫描”时Info.plist
我无法实际调用。ProcessedImageViewController
这是我的代码AppDelegate.swift
:
var launchedShortcutItem: UIApplicationShortcutItem?
var window: UIWindow?
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{
launchedShortcutItem = shortcutItem
}
return true
}
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: @escaping (Bool) -> Void) {
completionHandler(handleShortcutItem(item: shortcutItem))
}
func applicationDidBecomeActive(_ application: UIApplication) {
guard let shortcutItem = launchedShortcutItem else { return }
//If there is any shortcutItem,that will be handled upon the app becomes active
_ = handleShortcutItem(item: shortcutItem)
//We make it nil after perfom/handle method call for that shortcutItem action
launchedShortcutItem = nil
}
func handleShortcutItem(item: UIApplicationShortcutItem) -> Bool {
var handled = false
// Verify that the provided shortcutItem's type is one handled by the application.
let mainStoryboard = UIStoryboard.init(name: "Main", bundle: Bundle.main)
var reqVC: UIViewController!
reqVC = mainStoryboard.instantiateViewController(withIdentifier: "ProcessedImageViewController") as! ProcessedImageViewController
handled = true
if let homeVC = self.window?.rootViewController as? UINavigationController {
homeVC.pushViewController(reqVC, animated: true)
} else {
return false
}
return handled
}
当我尝试单击“快速操作”菜单中的“新扫描”时,我只会被带到根视图控制器(不是ProcessedImageViewController
)。
