iOS 获取Wi-Fi信息

导入头文件#import<SystemConfiguration/CaptiveNetwork.h>

添加代码

NSString *wifiName = nil;

CFArrayRef wifiInterfaces = CNCopySupportedInterfaces();

if (!wifiInterfaces) {

       return nil;

}

NSArray *interfaces = (__bridge NSArray *)wifiInterfaces;//获取Wi-Fi数组

for (NSString *interfaceName in interfaces) {

CFDictionaryRef dictRef = CNCopyCurrentNetworkInfo((__bridge CFStringRef)(interfaceName));

if (dictRef) {

NSDictionary *networkInfo = (__bridge NSDictionary *)dictRef;

NSLog(@"network info -> %@", networkInfo);//这里是当前链接的Wi-Fi的mac地址以及Wi-Fi的名字

wifiName = [networkInfo objectForKey:(__bridge NSString *)kCNNetworkInfoKeySSID];

CFRelease(dictRef);

}

}

CFRelease(wifiInterfaces);

DBLog(@"----------------------- wif = %@",wifiName);// 打印Wi-Fi的名字
