使用iOS13.6.1、Swift5.2.4、XCode11.6、

按照Apple 的文档，我尝试从我的应用程序中删除特定的 Siri 快捷方式。

下面的代码首先展示了我是如何创建 Siri 快捷方式的。

下面的代码显示了我尝试从我的应用程序中再次删除相同的 Siri 快捷方式。

不幸的是，Siri 快捷方式并未从我的应用程序中删除。

知道如何永久删除它吗？

extension EditMediaViewController {
    @available(iOS 12.0, *)
    func createSiriButton(documentID: String, invitationCode: String) -> INUIAddVoiceShortcutButton {
        
        let siriShortcutButton = INUIAddVoiceShortcutButton(style: .whiteOutline)
        
        let activity = NSUserActivity(activityType: "MyIdentifierStringCodeABCDEF")
        
        activity.title = "Test"
        activity.suggestedInvocationPhrase = "Test"
        
        activity.isEligibleForSearch = true
        activity.isEligibleForPrediction = true
        activity.persistentIdentifier = NSUserActivityPersistentIdentifier("MyIdentifierStringCodeABCDEF")
        activity.becomeCurrent()
        
        siriShortcutButton.shortcut = INShortcut(userActivity: activity)
        
        return siriShortcutButton
    }
}

extension EditMediaViewController: INUIAddVoiceShortcutButtonDelegate {
    @available(iOS 12.0, *)
    func present(_ addVoiceShortcutViewController: INUIAddVoiceShortcutViewController, for addVoiceShortcutButton: INUIAddVoiceShortcutButton) {
        addVoiceShortcutViewController.delegate = self
        addVoiceShortcutViewController.modalPresentationStyle = .formSheet
        present(addVoiceShortcutViewController, animated: true, completion: nil)
    }
    
    @available(iOS 12.0, *)
    func present(_ editVoiceShortcutViewController: INUIEditVoiceShortcutViewController, for addVoiceShortcutButton: INUIAddVoiceShortcutButton) {
        editVoiceShortcutViewController.delegate = self
        editVoiceShortcutViewController.modalPresentationStyle = .formSheet
        present(editVoiceShortcutViewController, animated: true, completion: nil)
    }
}

extension EditMediaViewController: INUIAddVoiceShortcutViewControllerDelegate {
    @available(iOS 12.0, *)
    func addVoiceShortcutViewController(_ controller: INUIAddVoiceShortcutViewController, didFinishWith voiceShortcut: INVoiceShortcut?, error: Error?) {
        controller.dismiss(animated: true, completion: nil)
    }
    
    @available(iOS 12.0, *)
    func addVoiceShortcutViewControllerDidCancel(_ controller: INUIAddVoiceShortcutViewController) {
        controller.dismiss(animated: true, completion: nil)
    }
}

extension EditMediaViewController: INUIEditVoiceShortcutViewControllerDelegate {
    @available(iOS 12.0, *)
    func editVoiceShortcutViewController(_ controller: INUIEditVoiceShortcutViewController, didUpdate voiceShortcut: INVoiceShortcut?, error: Error?) {
        controller.dismiss(animated: true, completion: nil)
    }
    
    @available(iOS 12.0, *)
    func editVoiceShortcutViewController(_ controller: INUIEditVoiceShortcutViewController, didDeleteVoiceShortcutWithIdentifier deletedVoiceShortcutIdentifier: UUID) {
        controller.dismiss(animated: true, completion: nil)
    }
    
    @available(iOS 12.0, *)
    func editVoiceShortcutViewControllerDidCancel(_ controller: INUIEditVoiceShortcutViewController) {
        controller.dismiss(animated: true, completion: nil)
    }
}

在这里我尝试删除相同的 Siri 快捷方式（但它不起作用 - 为什么？）：

let activity = NSUserActivity(activityType: "MyIdentifierStringCodeABCDEF")
let activityPersistentIdentifier = NSUserActivityPersistentIdentifier("MyIdentifierStringCodeABCDEF")
NSUserActivity.deleteSavedUserActivities(withPersistentIdentifiers: [activityPersistentIdentifier]) {
    print("one deleted")
}
INInteraction.deleteAll { (error) in
    print("all deleted")
}
INInteraction.delete(with: [activityPersistentIdentifier]) { (error) in
    print(error)
}
