iOS 获取ssid

- (NSString *)fetchSSIDInfo

{

NSString *ssid = nil;

NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();

for (NSString *ifnam in ifs) {

NSDictionary *info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);

if (info[@"SSID"]) {

ssid = info[@"SSID"];

}

}

return ssid;

}

注意：真机才好使， 模拟器 获取到的 是空的。
