在iOS 5.1中获取CellID,MCC,MNC,LAC和网络

1)使用单元监视器

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,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*,CFArrayRef*);
#define _CTServerConnectionCellMonitorCopyCellInfo(connection,tmp,cells) { struct CTResult res; _CTServerConnectionCellMonitorCopyCellInfo(&res,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,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每当当前的服务小区塔更改时发送.

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,CFNotificationSuspensionBehavior);

…

CTTelephonyCenterAddObserver(CTTelephonyCenterGetDefault(),NULL,callBACk,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,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)这返回当前服务的单元塔

struct CTResult
{
    int flag;
    int a;
};

id _CTServerConnectionCreate(CfallocatorRef,int*);

#ifdef __LP64__

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

#else

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

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

#endif

…

int CID,LAC,MNc;

id CTConnection = _CTServerConnectionCreate(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CoreTelephony函数都接受struct CTResult参数的问题.显然,64位版本的CoreTelephony导出这些函数,而没有结构化的CTResult参数.因为如果你像以前一样调用这些函数,那么你将会在ARM64中收到错误 – 参数会出错.我更新了函数声明,使它们可以在32位和64位ARM架构上工作.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架构构建项目,那么就没有这样的问题.您的应用程序将使用32位版本的CoreTelephony,该版本需要使用struct CTResult参数.

8.3更新

从iOS 8.3起,所有上述解决方案都需要授权才能工作

<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通知现在都要求该权限工作.例如,kCTmessageReceivedNotification也受到影响.
