获取wifi信息

最近有个项目需要获取手机附近wifi列表，查了许多资料发现，现在只能查到wifi的SSID，并且用到的是私有api，无法通过app store审核，这里记录一下，方便学习，新手勿喷，欢迎大神指教（wifi信息获取需要真机测试才能获取数据）

导入系统头文件

#import <SystemConfiguration/CaptiveNetwork.h>

实现代码

NSString *ssid = @"Not Found";
    NSString *macIp = @"Not Found";
    CFArrayRef myArray = CNCopySupportedInterfaces();
    if (myArray != nil) {
        CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
        if (myDict != nil) {
            NSDictionary *dict = (NSDictionary*)CFBridgingRelease(myDict);

            ssid = [dict valueForKey:@"SSID"];
            macIp = [dict valueForKey:@"BSSID"];
        }
    }
    UIAlertView *av = [[UIAlertView alloc] initWithTitle:ssid
                                                 message:macIp
                                                delegate:nil
                                       cancelButtonTitle:nil
                                       otherButtonTitles:@"OK", nil];
    [av show];
