【轉】獲取CID 和 LAC的方法

原文地址：http://stackoverflow.com/questions/13399659/get-cellid-mcc-mnc-lac-and-network-in-ios-5-1

在iOS5 ~ iOS8.3可是使用此方法，此處使用CoreTelephony.framework私有API。同時支持GSM和UMTS

1、使用電池監控器

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 每一個服務小區塔改變時被調用。

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、返回當前服務小區塔

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];

更新數據

在ARM64（iPhone 5S）有與接受所有CoreTelephony功能的問題struct CTResult爭論。顯然，CoreTelephony的​​64位版本的出口這些功能沒有struct CTResult說法。參數將是錯誤的-正因為如此，如果你調用這些函數像你過去那樣你會得到ARM64一個錯誤。我更新函數聲明，使他們在32位和64位ARM架構工作。我測試了它和它的作品在兩個iPhone 4S的和iPhone 5S。

這僅適用於ARM64。如果你建立你的項目為32位ARM架構則沒有這樣的問題。您的應用程序將使用CoreTelephony的​​32位版本，預計struct CTResult說法。

8.3更新

着iOS 8.3版本以上所有解決方案都需要有權工作

 

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

 

　　不僅電池監控器是受保護的，但它似乎像所有CoreTelephony通知現在要求權利的工作。例如，kCTMessageReceivedNotification也受到影響。
