iPhone은 개인 라이브러리없이 SSID를 얻습니다

네트워크의 SSID가 연결된 합법적 인 이유가있는 상용 앱이 있습니다. 타사 하드웨어 장치의 Adhoc 네트워크에 연결되어있는 경우 다른 방식으로 작동해야합니다. 인터넷에 연결되어 있습니다.

SSID를 얻는 것에 대해 내가 본 모든 것은 개인 라이브러리라는 것을 이해하는 Apple80211을 사용해야한다고 말합니다. 또한 개인 라이브러리를 사용하는 경우 Apple은 앱을 승인하지 않습니다.

나는 사과와 힘든 곳 사이에 갇혀 있습니까, 아니면 여기에 빠진 것이 있습니까?

iOS 7 또는 8에서이 작업을 수행 할 수 있습니다 (아래에 표시된대로 iOS 12+에 대한 자격 필요).

@import SystemConfiguration.CaptiveNetwork;

/** Returns first non-empty SSID network info dictionary.
 *  @see CNCopyCurrentNetworkInfo */
- (NSDictionary *)fetchSSIDInfo {
    NSArray *interfaceNames = CFBridgingRelease(CNCopySupportedInterfaces());
    NSLog(@"%s: Supported interfaces: %@", __func__, interfaceNames);

    NSDictionary *SSIDInfo;
    for (NSString *interfaceName in interfaceNames) {
        SSIDInfo = CFBridgingRelease(
            CNCopyCurrentNetworkInfo((__bridge CFStringRef)interfaceName));
        NSLog(@"%s: %@ => %@", __func__, interfaceName, SSIDInfo);

        BOOL isNotEmpty = (SSIDInfo.count > 0);
        if (isNotEmpty) {
    return SSIDInfo;

출력 예 :

2011-03-04 15:32:00.669 ShowSSID[4857:307] -[ShowSSIDAppDelegate fetchSSIDInfo]: Supported interfaces: (
2011-03-04 15:32:00.693 ShowSSID[4857:307] -[ShowSSIDAppDelegate fetchSSIDInfo]: en0 => {
    BSSID = "ca:fe:ca:fe:ca:fe";
    SSID = XXXX;
    SSIDDATA = <01234567 01234567 01234567>;

시뮬레이터에서는 if가 지원되지 않습니다. 장치에서 테스트하십시오.

iOS 12

기능에서 wifi 정보에 액세스 할 수 있어야합니다.

중요 iOS 12 이상에서이 기능을 사용하려면 Xcode에서 앱의 WiFi 정보 액세스 기능을 활성화하십시오. 이 기능을 활성화하면 Xcode는 자동으로 Access WiFi Information 권한을 자격 파일 및 앱 ID에 추가합니다. 설명서 링크

스위프트 4.2

func getConnectedWifiInfo() -> [AnyHashable: Any]? {

    if let ifs = CFBridgingRetain( CNCopySupportedInterfaces()) as? [String],
        let ifName = ifs.first as CFString?,
        let info = CFBridgingRetain( CNCopyCurrentNetworkInfo((ifName))) as? [AnyHashable: Any] {

        return info
    return nil


@elsurudo의 코드를 기반으로 정리 된 ARC 버전은 다음과 같습니다.

- (id)fetchSSIDInfo {
     NSArray *ifs = (__bridge_transfer NSArray *)CNCopySupportedInterfaces();
     NSLog(@"Supported interfaces: %@", ifs);
     NSDictionary *info;
     for (NSString *ifnam in ifs) {
         info = (__bridge_transfer NSDictionary *)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
         NSLog(@"%@ => %@", ifnam, info);
         if (info && [info count]) { break; }
     return info;

iOS 10 이상 업데이트

CNCopySupportedInterfaces는 iOS 10에서 더 이상 사용되지 않습니다. ( API Reference )

당신은 가져와야 에서 SystemConfiguration / CaptiveNetwork.h을 추가합니다 SystemConfiguration.framework을 (빌드 단계에서) 대상의 링크 라이브러리에.

다음은 신속한 코드 조각입니다 (RikiRiocma 's Answer) :

import Foundation
import SystemConfiguration.CaptiveNetwork

public class SSID {
    class func fetchSSIDInfo() -> String {
        var currentSSID = ""
        if let interfaces = CNCopySupportedInterfaces() {
            for i in 0..<CFArrayGetCount(interfaces) {
                let interfaceName: UnsafePointer<Void> = CFArrayGetValueAtIndex(interfaces, i)
                let rec = unsafeBitCast(interfaceName, AnyObject.self)
                let unsafeInterfaceData = CNCopyCurrentNetworkInfo("\(rec)")
                if unsafeInterfaceData != nil {
                    let interfaceData = unsafeInterfaceData! as Dictionary!
                    currentSSID = interfaceData["SSID"] as! String
        return currentSSID

(Important: CNCopySupportedInterfaces returns nil on simulator.)

For Objective-c, see Esad's answer here and below

+ (NSString *)GetCurrentWifiHotSpotName {    
    NSString *wifiName = nil;
    NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
    for (NSString *ifnam in ifs) {
        NSDictionary *info = (__bridge_transfer id)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam);
        if (info[@"SSID"]) {
            wifiName = info[@"SSID"];
    return wifiName;


As of iOS 9 Captive Network is deprecated*. (source)

*No longer deprecated in iOS 10, see above.

It's recommended you use NEHotspotHelper (source)

You will need to email apple at and request entitlements. (source)

Sample Code (Not my code. See Pablo A's answer):

for(NEHotspotNetwork *hotspotNetwork in [NEHotspotHelper supportedNetworkInterfaces]) {
    NSString *ssid = hotspotNetwork.SSID;
    NSString *bssid = hotspotNetwork.BSSID;
    BOOL secure =;
    BOOL autoJoined = hotspotNetwork.autoJoined;
    double signalStrength = hotspotNetwork.signalStrength;

Side note: Yup, they deprecated CNCopySupportedInterfaces in iOS 9 and reversed their position in iOS 10. I spoke with an Apple networking engineer and the reversal came after so many people filed Radars and spoke out about the issue on the Apple Developer forums.

This works for me on the device (not simulator). Make sure you add the systemconfiguration framework.

#import <SystemConfiguration/CaptiveNetwork.h>

+ (NSString *)currentWifiSSID {
    // Does not work on the simulator.
    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;

This code work well in order to get SSID.

#import <SystemConfiguration/CaptiveNetwork.h>

@implementation IODAppDelegate

@synthesize window = _window;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

CFArrayRef myArray = CNCopySupportedInterfaces();
CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
NSLog(@"Connected at:%@",myDict);
NSDictionary *myDictionary = (__bridge_transfer NSDictionary*)myDict;
NSString * BSSID = [myDictionary objectForKey:@"BSSID"];
NSLog(@"bssid is %@",BSSID);
// Override point for customization after application launch.
return YES;

And this is the results :

Connected at:{
BSSID = 0;
SSID = "Eqra'aOrange";
SSIDDATA = <45717261 27614f72 616e6765>;


If you are running iOS 12 you will need to do an extra step. I've been struggling to make this code work and finally found this on Apple's site: "Important To use this function in iOS 12 and later, enable the Access WiFi Information capability for your app in Xcode. When you enable this capability, Xcode automatically adds the Access WiFi Information entitlement to your entitlements file and App ID."

See CNCopyCurrentNetworkInfo in CaptiveNetwork:

Here's the short & sweet Swift version.

Remember to link and import the Framework:

import UIKit
import SystemConfiguration.CaptiveNetwork

Define the method:

func fetchSSIDInfo() -> CFDictionary? {
    if let
        ifs = CNCopySupportedInterfaces().takeUnretainedValue() as? [String],
        ifName = ifs.first,
        info = CNCopyCurrentNetworkInfo((ifName as CFStringRef))
        return info.takeUnretainedValue()
    return nil

Call the method when you need it:

if let
    ssidInfo = fetchSSIDInfo() as? [String:AnyObject],
    ssID = ssidInfo["SSID"] as? String
    println("SSID: \(ssID)")
} else {
    println("SSID not found")

As mentioned elsewhere, this only works on your iDevice. When not on WiFi, the method will return nil – hence the optional.
