判断设备SIM卡

在.h里面写上在@end之前就行

//TODO:GET SIM
extern NSString*
const kCTSMSMessageReceivedNotification;
extern NSString*
const kCTSMSMessageReplaceReceivedNotification;
extern NSString*
const kCTSIMSupportSIMStatusNotInserted;
extern NSString*
const kCTSIMSupportSIMStatusReady; 

id CTTelephonyCenterGetDefault(void);
void CTTelephonyCenterAddObserver(id,id,CFNotificationCallback,NSString*,void*,int);
void CTTelephonyCenterRemoveObserver(id,id,NSString*,void*);
int CTSMSMessageGetUnreadCount(void); 

int CTSMSMessageGetRecordIdentifier(void * msg);
NSString * CTSIMSupportGetSIMStatus();  
NSString * CTSIMSupportCopyMobileSubscriberIdentity(); 

id  CTSMSMessageCreate(void* unknow/*always 0*/,NSString* number,NSString* text);
void * CTSMSMessageCreateReply(void* unknow/*always 0*/,void * forwardTo,NSString* text); 

void* CTSMSMessageSend(id server,id msg); 

NSString *CTSMSMessageCopyAddress(void *,
void *);
NSString *CTSMSMessageCopyText(void *,
void *);
//END TODO:GET SIM

在.m中调用：

+ (BOOL)getSIM{
    BOOL isSIM;
    if ([CTSIMSupportGetSIMStatus()
isEqualToString:kCTSIMSupportSIMStatusNotInserted]) {
        isSIM = YES;
    }else{
        isSIM = NO;
    }    
    return isSIM;
}
