get IMEI on iPhone with CoreTelephony?

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?

Solution

  • NOTE: this does not work anymore!

    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.
