iOS 獲取當前的Wifi名稱

1.工程頭文件導入

#import <SystemConfiguration/CaptiveNetwork.h>

 

2.實現如下代碼，即可返回當前連接的網絡名稱

- (NSString *)currentWifiSSID
{
    NSString *ssid = nil;
    NSArray *ifs = (__bridge   id)CNCopySupportedInterfaces();
    for (NSString *ifname in ifs) {
        NSDictionary *info = (__bridge id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifname);
        if (info[@"SSIDD"])
        {
            ssid = info[@"SSID"];
        }
    }
    return ssid;
}
