极客班项目：蓦然

Posted on Edited on

遇到的点

  • 参考微信朋友圈,发布新照片后,动态插入原有的朋友圈顶部, 我的理解是存入本地缓存数据库,后台异步上次到服务器.

源码见 GitHub：https://github.com/gewill/Mo-Ran

v0.1 b1

date: 2015.09.20

  • 发布照片按钮 和 发布照片页面
  • 复用先峰小组的 login.StoryBoard
  • AppDelegate 分别实现：跳转登陆和主界面方面

登陆按钮

使用 AFNetworking 的 AFHTTPRequestOperationManager
- POST:parameters:success:failure: 方法，提交 json
格式数据，收到成功或者失败的数据 json。具体格式参考文档。

主要是处理 AFHTTPRequestOperation 的 responseObject 的 json 数据。

遇到网络问题，直接想到 Google，但是搜索的不得要领，无果。最后想到 Charles 网络调试， Request 和 Response 一目了然。非常棒的工具。然后认真查看 API 相关参数的类型的：属性和方法。

Cocoapods改为本地添加，网络不稳定也是无奈。
