如何快速获取WWDC2013的所有视频及文档

来源：互联网发布：上淘宝买东西怎么注册编辑：程序博客网时间：2024/05/17 04:55
WWDC2013结束已经有好几天了，但是有些细节在看直播时并未完全理解。虽然apple方面发布了WWDC的应用，可惜只能在ipad之类的设备上看。（不能在电脑上看不幸福）。遂寻找各种手段获取视频的下载地址。
经过5000多次（略假）尝试，咱终于找到了获取视频地址比较靠谱的方法。我的做法是先用ipad之类的下载WWDC并刷新视频栏的内容，使用iTools在某个文件夹（等我进水的ipad能正常使用后再说明）中找到“Videos.json”这个文件。用xcode打开后会看到这些东西：
所有的视频地址及标签包含在json里，想有效率地读取json中的内容，我们需要动手写一段读取代码，代码如下：
