怎样在ios上获取wifi的相关信息？

[QQQ_Jinn]

rt 怎样获取设备的wifi信息，如信号强弱，热点名称等

[shixuehuiab]

libHandle = dlopen("/System/Library/SystemConfiguration/IPConfiguration.bundle/IPConfiguration", RTLD_LAZY);// iOS 5 之后的用 参考这里： http://blog.csdn.net/robincui2011/article/details/8853401 我验证过，iOS5和iOS7上可以，iOS6估计也没问题

[愤怒的刚哥]

这是调用的私有API么 能上线么 谁能给我发一份 不胜感激 [e-mail]

很好，不错
