Swift:在AppDelegate中从UNTextInputNotificationAction获取内容

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
    // ...
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        // 检查通知响应是否是UNTextInputNotificationResponse类型
        guard let textResponse = response as? UNTextInputNotificationResponse else {
            completionHandler()
            return
        }
        
        // 获取用户输入的文本内容
        let inputText = textResponse.userText
        print("用户输入的内容：\(inputText)")
        
        completionHandler()
    }
    
    // ...
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // ...
    
    UNUserNotificationCenter.current().delegate = self
    
    // ...
    
    return true
