【转】获取CID 和 LAC的方法

原文地址：http://*.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，此处使用CoreTelephony.framework私有API。同时支持GSM和UMTS

1、使用电池监控器

 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 = ;
     CFArrayRef cells = NULL;
     _CTServerConnectionCellMonitorCopyCellInfo(connection, (void*)&tmp, &cells);
     if (cells == NULL)
     {
         return ;
     }

     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 ;
 }

2、使用CTTelephonyCenter

kCTRegistrationCellChangedNotification 每一个服务小区塔改变时被调用。

 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];

更新数据

在ARM64（iPhone 5S）有与接受所有CoreTelephony功能的问题struct CTResult争论。显然，CoreTelephony的​​64位版本的出口这些功能没有struct CTResult说法。参数将是错误的-正因为如此，如果你调用这些函数像你过去那样你会得到ARM64一个错误。我更新函数声明，使他们在32位和64位ARM架构工作。我测试了它和它的作品在两个iPhone 4S的和iPhone 5S。

这仅适用于ARM64。如果你建立你的项目为32位ARM架构则没有这样的问题。您的应用程序将使用CoreTelephony的​​32位版本，预计struct CTResult说法。

8.3更新

着iOS 8.3版本以上所有解决方案都需要有权工作

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

　　不仅电池监控器是受保护的，但它似乎像所有CoreTelephony通知现在要求权利的工作。例如，kCTMessageReceivedNotification也受到影响。
