swift 版本

import SystemConfiguration.CaptiveNetwork

        var wifiName : String = ""
        let wifiInterfaces = CNCopySupportedInterfaces()
        if wifiInterfaces == nil {
            
        }
        
        let interfaceArr = CFBridgingRetain(wifiInterfaces!) as! Array<String>
        if interfaceArr.count > 0 {
            let interfaceName = interfaceArr[0] as CFString
            let ussafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
            
            if (ussafeInterfaceData != nil) {
                let interfaceData = ussafeInterfaceData as! Dictionary<String, Any>
                wifiName = interfaceData["SSID"]! as! String
            }
        }

oc  版本 
#import <SystemConfiguration/CaptiveNetwork.h>
+ (NSString *)ssid{
    NSString *ssid = nil;
    CFArrayRef myArray = CNCopySupportedInterfaces();
    if (myArray) {
        CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
        if (myDict) {
            NSDictionary *dict = (NSDictionary *)CFBridgingRelease(myDict);
            ssid = [dict valueForKey:@"SSID"];
        }
        CFRelease(myArray);
    }
    return ssid;
}
