代码实现

• HMUserAccount 增加属性

  /// 用户昵称
  var screen_name: String?
  /// 用户头像地址（大图），180×180像素
  var avatar_large: String?
  

• 修改 description

  // 对象打印信息
  override var description: String {
    let keys = ["access_token", "uid", "expires_in", "expiresDate", "screen_name", "avatar_large"]
    return dictionaryWithValues(forKeys: keys).description
  }
  

• 修改 归档 和 解档 函数,增加screen_name和avatar_large 属性的 归档 和 解档

  // MARK: - 归档和解档
  /// 归档
  func encode(with aCoder: NSCoder) {
    aCoder.encode(access_token, forKey: "access_token")
    aCoder.encode(uid, forKey: "uid")
    aCoder.encode(expires_in, forKey: "expires_in")
    aCoder.encode(expiresDate, forKey: "expiresDate")
    aCoder.encode(screen_name, forKey: "screen_name")
    aCoder.encode(avatar_large, forKey: "avatar_large")
  }
  /// 解档
  required init?(coder aDecoder: NSCoder) {
    access_token = aDecoder.decodeObject(forKey: "access_token") as? String
    uid = aDecoder.decodeObject(forKey: "uid") as? String
    expires_in = aDecoder.decodeDouble(forKey: "expires_in")
    expiresDate = aDecoder.decodeObject(forKey: "expiresDate") as? Date
    screen_name = aDecoder.decodeObject(forKey: "screen_name") as? String
    avatar_large = aDecoder.decodeObject(forKey: "avatar_large") as? String
  }
  

• 在HMUserAccountViewModel 添加 加载用户信息 的方法: loadUserInfo

  /**
  加载用户信息
  - parameter loadUserInfoCallBack: 回调
  */
  func loadUserInfo(completion: @escaping (Error?) -> ()) {
    // 判断access_token
    guard let access_token = userAccount?.access_token else {
        print("access_token为空")
        return
    }
  
    // 判断uid
    guard let uid = userAccount?.uid else {
        print("uid为空")
        return
    }
  
    // 5.url
    let urlString = "https://api.weibo.com/2/users/show.json"
  
    // 6.准备参数
    let parameters = ["access_token": access_token, "uid": uid]
  
    HMNetworkTool.shared.request(method: .GET, URLString: urlString, parameters: parameters, progress: nil, success: { (_, result) in
  
        let dict = result as? [String: Any]
  
        // 获取数据
        self.userAccount?.screen_name = dict?["screen_name"] as? String
        self.userAccount?.avatar_large = dict?["avatar_large"] as? String
  
        // 保存起来
        self.saveUserAccount()
  
        // 执行闭包
        completion(nil)
  
        }) { (_, error) in
            completion(error)
    }
  }
  

• 在 HMWelcomeViewController 的 viewDidLoad 方法,去加载用户最新数据

  override func viewDidLoad() {
    super.viewDidLoad()
  
    setupUI()
  
    // 显示沙盒保存的用户的头像
    if let avatar_large = HMUserAccountViewModel.shared.userAccount?.avatar_large {
        let url = URL(string: avatar_large)
        iconView.sd_setImage(with: url, placeholderImage: UIImage(named: "avatar_default_big"))
    }
  
    // 获取最新用户数据
    HMUserAccountViewModel.shared.loadUserInfo { (error: Error?) in
        // 显示沙盒保存的用户的头像
        if let avatar_large = HMUserAccountViewModel.shared.userAccount?.avatar_large {
            let url = URL(string: avatar_large)
            self.iconView.sd_setImage(with: url, placeholderImage: UIImage(named: "avatar_default_big"))
        }
    }
  }
