今天无意间看到一个App：My Data Mgr

https://itunes.apple.com/cn/app/wo-liu-liang-guan-li-my-data/id477865384?mt=8

这个App有一个功能，是可以获取本机已经安装的程序，个人对此很感兴趣，于是在网上查找了一下相关的教程，目前只找到一个开源的框架：iHasApp。这个框架的实现方式实在是变态，不多说。直接有图有真相了

这个框架把App对应的ID全部都整理起来，然后找到对应的App就去网上去查，所以它维护了一个比较大的JSON文件来保存这些对应关系。

[代码]c#/cpp/oc代码：

01	"navfree-usa": [405922167],

02	"navigon": [353748243],

03	"navigonALB": [353748243],

04	"navigonAND": [353748243],

05	"navigonAUT": [353748243],

28	"navigonLIE": [353748243],

29	"navigonLTU": [353748243],

但是这个并不是我想要找的方法，未完待续，放上代码
