iOS一个动态加载数据到UITableView的源代码例子阅读笔记。

概述

应用程序代理类设置顶层视图控制，并处理了获取RSS信息(XML格式)的连接。RSS信息获取完毕后，使用了任务队列执行xml解析操作。等解析完成后将记录数据添加到记录数组中并刷新顶层视图。 顶层视图控制器控制显示记录数据，并在渲染可见元素时(满足一定条件)下载(默认异步)相应记录中的图片，然后显示出来。

  • 语境说明
    • 应用程序代理类：LazyTableAppDelegate
    • 顶层视图控制器：RootViewController
    • 负责解析XML的类：ParseOperation
    • 负责下载图片的类：IconDownloader

<Qt Threading Basics> Document Reading Note

What are threads

Blabla... thread is tiny process that share the memory.

  • Thread can run on multicore CPUs. But how about The C10K problem?

GUI Thread and Worker Thread

  • Qt GUI must run in "main thread"

Simultaneous Access to Data

  • Simultaneous access an shared object will be faster that communicate in process, but it's also dangerous.
  • Some cases will cause danger

Concepts

  • Node : A content section
  • Menu : List subnodes
  • Cross-Reference : Link to some node
  • Index : um...index.
  • Table of Contents : Show node hierarchy
  • History : Just like borwser page history
  • Recents : A list show recent visited nodes
