我知道三种在iOS 5.x - 7.x上如何实现的方法,它们都使用了CoreTelephony.framework中的私有API。支持GSM和UMTS。
1)使用手机监视器。
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, 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
在当前服务的基站塔发生变化时发送。
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) 这将返回当前服务的基站
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
在ARM64架构(iPhone 5S)上,所有接受struct CTResult
参数的CoreTelephony函数都存在问题。显然,CoreTelephony的64位版本会导出这些函数时没有struct CTResult
参数。因此,如果像过去一样调用这些函数,则在ARM64上会出现错误-参数将是错误的。我更新了函数声明,使它们适用于32位和64位ARM架构。我进行了测试,在iPhone 4S和iPhone 5S上都可以正常工作。
这仅适用于ARM64。如果您为32位ARM架构构建项目,则不存在此问题。您的应用程序将使用期望struct CTResult
参数的32位版本的CoreTelephony。
8.3 更新
iOS 8.3版本开始,所有以上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>
不仅仅是单个单元监视器被保护,而且似乎所有的CoreTelephony通知现在都需要该权限才能工作。例如,kCTMessageReceivedNotification
也受到影响。
suscriberCellularProvider
而不是subscriberCellularProvider
现在它可以为 MNC 和 MCC 工作了...现在我需要获取 CellID 和 LAC,这可能会有一些困难... - poorDeveloper
