iPhone判斷是否已插入SIM卡

判斷 iPhone 是否插入了 SIM 卡，能夠參考蘋果官網的 systemconfigure framework 教程，將下面的代碼複製到頭文件

#import <Foundation/Foundation.h>

@interface NSObjectiveCPlusPLus : NSObject

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

 

    而後引入 CoreTelephony.framework ，便可利用 [CTSIMSupportGetSIMStatus()  isEqualToString:kCTSIMSupportSIMStatusNotInserted] 進行判斷。

用法：

//判斷是否插入
if simStatus.isEqualToString(kCTSIMSupportSIMStatusNotInserted) {
            
            //未插入SIM卡
        }else {
            
            //撥打電話
            var urlString = "tel:" + businessDetailModel.serviceTel!
            UIApplication.sharedApplication().openURL(NSURL(string: urlString)!)
        }
