IOS零碎技术整理（三）——获取WIFI列表
1.这个功能的开发是基于MobileApple80211框架，现在是私有框架，里面的API都是私有API。如果使用这些API，可能会导致应用无法在应用商店上架或ios版本升级过程与私有API不兼容，导致程序莫名挂起或数据获取失败
2.终端必须越狱，程序必须部署到终端的/Applications目录下才能获得超级用户权限才能访问wifi

(1. The development of this function is based on the mobileapple80211 framework. Now it is a private framework, and the APIs in it are private APIs.
If these APIs are used, the application may not be available in the app store, or the IOS version upgrade process is incompatible with the private API, resulting in program suspension or data acquisition failure
2. The terminal must escape from prison, and the program must be deployed to the / applications directory of the terminal to obtain super user permission and access WiFi
