在iOS 5.1中获取CellID,MCC,MNC,LAC和网络

Question

我需要检索iOS 5.1(iPhone 4S)中当前服务细胞塔的CellID,MCC,MNC,LAC和网络(GSM,3G).我知道这些信息是可用的,因为我可以在FieldTest模式下看到它(在调用****3001#12345#****后可访问).我想它可以通过私有/未记录的iOS框架访问.

在问题iphone中,检查cellId/Lac的值,作者表示我可以在iOS上获取无线电信息cellId,Lac,MNC,MCC,但是没有提供有关如何执行此操作的信息.

谁能告诉我如何获取这些信息？

Answer 1

我知道如何在iOS 5.x上运行它的三种方法 - 7.x. 所有这些都使用来自CoreTelephony.framework的私有API.支持GSM和UMTS.

1)使用细胞监测器

struct CTResult
{
    int flag;
    int a;
};

extern CFStringRef const kCTCellMonitorCellType;
extern CFStringRef const kCTCellMonitorCellTypeServing;
extern CFStringRef const kCTCellMonitorCellTypeNeighbor;
extern CFStringRef const kCTCellMonitorCellId;
extern CFStringRef const kCTCellMonitorLAC;
extern CFStringRef const kCTCellMonitorMCC;
extern CFStringRef const kCTCellMonitorMNC;
extern CFStringRef const kCTCellMonitorUpdateNotification;

id _CTServerConnectionCreate(CFAllocatorRef, void*, int*);
void _CTServerConnectionAddToRunLoop(id, CFRunLoopRef, CFStringRef);

#ifdef __LP64__

void _CTServerConnectionRegisterForNotification(id, CFStringRef);
void _CTServerConnectionCellMonitorStart(id);
void _CTServerConnectionCellMonitorStop(id);
void _CTServerConnectionCellMonitorCopyCellInfo(id, void*, CFArrayRef*);

#else

void _CTServerConnectionRegisterForNotification(struct CTResult*, id, CFStringRef);
#define _CTServerConnectionRegisterForNotification(connection, notification) { struct CTResult res; _CTServerConnectionRegisterForNotification(&res, connection, notification); }

void _CTServerConnectionCellMonitorStart(struct CTResult*, id);
#define _CTServerConnectionCellMonitorStart(connection) { struct CTResult res; _CTServerConnectionCellMonitorStart(&res, connection); }

void _CTServerConnectionCellMonitorStop(struct CTResult*, id);
#define _CTServerConnectionCellMonitorStop(connection) { struct CTResult res; _CTServerConnectionCellMonitorStop(&res, connection); }

void _CTServerConnectionCellMonitorCopyCellInfo(struct CTResult*, id, void*, CFArrayRef*);
#define _CTServerConnectionCellMonitorCopyCellInfo(connection, tmp, cells) { struct CTResult res; _CTServerConnectionCellMonitorCopyCellInfo(&res, connection, tmp, cells); }

#endif

...

id CTConnection = _CTServerConnectionCreate(NULL, CellMonitorCallback, NULL);
_CTServerConnectionAddToRunLoop(CTConnection, CFRunLoopGetCurrent(), kCFRunLoopCommonModes);
_CTServerConnectionRegisterForNotification(CTConnection, kCTCellMonitorUpdateNotification);
_CTServerConnectionCellMonitorStart(CTConnection);

int CellMonitorCallback(id connection, CFStringRef string, CFDictionaryRef dictionary, void *data)
{
    int tmp = 0;
    CFArrayRef cells = NULL;
    _CTServerConnectionCellMonitorCopyCellInfo(connection, (void*)&tmp, &cells);
    if (cells == NULL)
    {
        return 0;
    }

    for (NSDictionary* cell in (NSArray*)cells)
    {
        int LAC, CID, MCC, MNC;

        if ([cell[(NSString*)kCTCellMonitorCellType] isEqualToString:(NSString*)kCTCellMonitorCellTypeServing])
        {
            LAC = [cell[(NSString*)kCTCellMonitorLAC] intValue];
            CID = [cell[(NSString*)kCTCellMonitorCellId] intValue];
            MCC = [cell[(NSString*)kCTCellMonitorMCC] intValue];
            MNC = [cell[(NSString*)kCTCellMonitorMNC] intValue];
        }
        else if ([cell[(NSString*)kCTCellMonitorCellType] isEqualToString:(NSString*)kCTCellMonitorCellTypeNeighbor])
        {
        }
    }

    CFRelease(cells);

    return 0;
}

2)使用CTTelephonyCenter

kCTRegistrationCellChangedNotification 每当当前服务小区塔被改变时发送.

extern CFStringRef const kCTRegistrationCellChangedNotification;
extern CFStringRef const kCTRegistrationGsmLac;
extern CFStringRef const kCTRegistrationLac;
extern CFStringRef const kCTRegistrationGsmCellId;
extern CFStringRef const kCTRegistrationCellId;

CFStringRef CTSIMSupportCopyMobileSubscriberCountryCode(CFAllocatorRef);
CFStringRef CTSIMSupportCopyMobileSubscriberNetworkCode(CFAllocatorRef);

id CTTelephonyCenterGetDefault();
void CTTelephonyCenterAddObserver(id, void, CFNotificationCallback, CFStringRef, void, CFNotificationSuspensionBehavior);

...

CTTelephonyCenterAddObserver(CTTelephonyCenterGetDefault(), NULL, callback, NULL, NULL, CFNotificationSuspensionBehaviorHold);

void callback(CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo)
{
    NSString* notification = (NSString*)name;
    NSDictionary *cellInfo = (NSDictionary*)userInfo;

    if ([notification isEqualToString:(NSString*)kCTRegistrationCellChangedNotification])
    {
        int LAC, CID, MCC, MNC;

        if (cellInfo[(NSString*)kCTRegistrationGsmLac])
        {
            LAC = [cellInfo[(NSString*)kCTRegistrationGsmLac] intValue];
        }
        else if (data[(NSString*)kCTRegistrationLac])
        {
            LAC = [cellInfo[(NSString*)kCTRegistrationLac] intValue];
        }

        if (cellInfo[(NSString*)kCTRegistrationGsmCellId])
        {
            CID = [cellInfo[(NSString*)kCTRegistrationGsmCellId] intValue];
        }
        else if (cellInfo[(NSString*)kCTRegistrationCellId])
        {
            CID = [cellInfo[(NSString*)kCTRegistrationCellId] intValue];
        }

        MCC = [[(NSString*)CTSIMSupportCopyMobileSubscriberCountryCode(NULL) autorelease] intValue];
        MNC = [[(NSString*)CTSIMSupportCopyMobileSubscriberNetworkCode(NULL) autorelease] intValue];
    }
}

3)这返回当前服务小区塔

struct CTResult
{
    int flag;
    int a;
};

id _CTServerConnectionCreate(CFAllocatorRef, void*, int*);

#ifdef __LP64__

void _CTServerConnectionGetLocationAreaCode(id, int*);
void _CTServerConnectionGetCellID(id, int*);

#else

void _CTServerConnectionGetLocationAreaCode(struct CTResult*, id, int*);
#define _CTServerConnectionGetLocationAreaCode(connection, LAC) { struct CTResult res; _CTServerConnectionGetLocationAreaCode(&res, connection, LAC); }

void _CTServerConnectionGetCellID(struct CTResult*, id, int*);
#define _CTServerConnectionGetCellID(connection, CID) { struct CTResult res; _CTServerConnectionGetCellID(&res, connection, CID); }

#endif

...

int CID, LAC, MCC, MNC;

id CTConnection = _CTServerConnectionCreate(NULL, NULL, NULL);
_CTServerConnectionGetCellID(CTConnection, &CID);
_CTServerConnectionGetLocationAreaCode(CTConnection, &LAC);
MCC = [[(NSString*)CTSIMSupportCopyMobileSubscriberCountryCode(NULL) autorelease] intValue];
MNC = [[(NSString*)CTSIMSupportCopyMobileSubscriberNetworkCode(NULL) autorelease] intValue];

UPDATE

在ARM64(iPhone 5S)上,所有接受struct CTResult参数的CoreTelephony函数都存在问题.显然,64位版本的CoreTelephony无需struct CTResult参数即可导出这些函数.因此,如果你像过去那样调用这些函数,你将在ARM64上出错 - 参数将是错误的.我更新了函数声明,以便它们可以在32位和64位ARM体系结构上工作.我测试了它,它适用于iPhone 4S和iPhone 5S.

这仅适用于ARM64.如果您为32位ARM体系结构构建项目,则不存在此类问题.您的应用程序将使用32位版本的CoreTelephony,它需要struct CTResult参数.

8.3更新

从iOS 8.3开始,上述所有解决方案都需要有权使用

<key>com.apple.CommCenter.fine-grained</key>
<array>
    <string>spi</string>
</array>

不仅单元监视器受到保护,而且似乎所有CoreTelephony通知现在都需要该权限才能工作.例如,kCTMessageReceivedNotification也受到影响.

Answer 2

suscriberCellularProvider 是一个对象方法（与类方法相比）。

您可以在这里查看如何使用它： 确定 iPhone 用户的国家/地区

我认为CTCarrier有MCC和MNC。
