1. 关于检测应用安装情况研究---
(1).利用URL scheme，看对于某一应用特有的url scheme，有没有响应。如果有响应，就说明安装了这个特定的app。
对于URL Scheme的使用请参看我之前的文章。
市场上有一部分应用检测安装是利用第三方ihasapp的接口获取的，目前ihasapp接口可以返回5000多个应用的URL Scheme。https://ihasapp.herokuapp.com/api/schemeApps.json 遍历列表，里面提供了每个应用的URL Scheme，客户端利用application的openurl函数，一个一个在iphone上尝试打开这些app，不过这种实现方式会很快把你的iphone变成暖手宝.
(2)利用一些方法获得当前正在运行的进程信息，从进程信息中获得安装的app信息。
代码请参看http://forrst.com/posts/UIDevice_Category_For_Processes-h1H
缺点是打印输出的应用名称：让你找不到北，最熟悉的是找到tmall.
(3)破解手机的私有API可参看
关于越狱情况获取iphone用户安装的app列表：（这是从一篇讨论 360因为侵犯用户隐私被苹果下架 的文章中看来的）
- 已安装app列表 /private/var/mobile/Library/Caches/com.apple.mobile.installation.plist
- 用户相片 /var/mobile/Media/DCIM/100APPLE/
- 音乐目录 /var/mobile/Media/iTunes_Control/Music/
/private/ ，/var/都是合法app不能访问的目录，但是你的iphone一旦越狱，app就可以为所欲为。
2.关于流量检测研究-----
(1) 通过读取系统网络接口信息，可以获取当前iphone设备的流量相关信息， 但统计的是上次开机至今的流量信息。代码如下：

continue;

continue;

可以获取内容有：
WIFI接收数据流量，WIFI发送数据流量；
3G和GPRS接收数据流量，3G和GPRS发送数据流量；
通过查看其他流量软件具体到每日每月总流量，越狱情况下应该可以实现这每日每月总流量检测， 但我还未找到获取单个应用的流量信息私有API，大家有知道怎么获取的，也分享下，呵呵。
