get IMEI on iPhone with CoreTelephony?

问题:

I have tried the accepted answer of How to get IMEI on iPhone? but I got an empty string.

I saw somebody suggested to use CoreTelephony framework, but I am not sure how to use it to obtain the IMEI.

Any suggestion on how to use this private API?

Haven't tested on any new iOS.

You have to add CoreTelephony.h to your project. Make sure the header has

int * _CTServerConnectionCopyMobileEquipmentInfo (
                                              struct CTResult * Status,
                                              struct __CTServerConnection * Connection,
                                              CFMutableDictionaryRef * Dictionary
                                              );

Then you can try this code:

#import "CoreTelephony.h"
void getImei() {
struct CTResult it;
CFMutableDictionaryRef kCTDict;
conn = _CTServerConnectionCreate(kCFAllocatorDefault, ConnectionCallback,NULL);
_CTServerConnectionCopyMobileEquipmentInfo(&it, conn, &kCTDict);
NSLog (@ "kCTDict is %@", kCTDict);
CFStringRef meid = CFDictionaryGetValue(kCTDict, CFSTR("kCTMobileEquipmentInfoMEID"));
NSLog (@ "kCTMobileEquipmentInfoMEID is %@", meid);
CFStringRef mobileId = CFDictionaryGetValue(kCTDict,    CFSTR("kCTMobileEquipmentInfoCurrentMobileId"));
NSLog (@ "kCTMobileEquipmentInfoCurrentMobileId is %@", mobileId);
}

Here's the CoreTelephony.h

You can check my example project.

Note: I don't think the code works on the simulator and your app might get rejected.
