前言

大家都知道隨著人工智慧的發展，會掀起來另外一個工業革命，而語音識別就是人工智慧的初始階段，但是每個公司做的都不一樣，涉及到一系列的語音的採集和演算法實現，蘋果的Siri就是業界語音識別的代表性的產品。接下來的幾篇我們就詳細解析一下SiriKit這個框架。感興趣的可以看下面幾篇文章。

原始碼

1. Swift

首先看一下程式碼結構

下面看一下原始碼

1. AppDelegate.swift

import UIKit
import IntentsUI
import ArticleKit

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    window = UIWindow(frame: UIScreen.main.bounds)
    nav = UINavigationController(rootViewController: rootVC)
    window?.rootViewController = nav
    window?.makeKeyAndVisible()
    
    ArticleManager.loadArticles()
    return true
  }
  
  func applicationWillResignActive(_ application: UIApplication) {
    ArticleManager.writeArticlesToDisk()
  }
  
  func applicationWillEnterForeground(_ application: UIApplication) {
    ArticleManager.loadArticles()
    rootVC.viewWillAppear(false)
  }
  
  func application(_ application: UIApplication, willContinueUserActivityWithType userActivityType: String) -> Bool {
    if userActivityType == "com.razeware.NewArticle" {
      return true
    }
    
    return false
  }
