You can also search for identity in keychain if you store this information there:

+ (SecIdentityRef)dumpSecIdentityRef
{
OSStatus    err;
CFArrayRef  result;
CFIndex     resultCount;
CFIndex     resultIndex;

result = NULL;
err = SecItemCopyMatching((__bridge CFDictionaryRef) [NSDictionary dictionaryWithObjectsAndKeys:
                                                      (__bridge id)kSecClassIdentity,
                                                      kSecClass, kSecMatchLimitAll,
                                                      kSecMatchLimit, kCFBooleanTrue,
                                                      kSecReturnRef, kCFBooleanTrue,
                                                      kSecReturnAttributes, nil],
                          (CFTypeRef *) &result);

if ((result != NULL) && (err == noErr)) {

    NSMutableArray *identitiesArray = [NSMutableArray new];

    resultCount = CFArrayGetCount(result);
    for (resultIndex = 0; resultIndex < resultCount; resultIndex++) {
        NSDictionary *  thisResult;
        thisResult = (__bridge NSDictionary *) CFArrayGetValueAtIndex(result, resultIndex);
        NSLog(@"%@", (__bridge id)(result));
        [identitiesArray addObject:thisResult];
    }

    CFRelease(result);
    //TO DO - choose correct identity object from array.
    SecIdentityRef myIdentity = (__bridge SecIdentityRef)([[identitiesArray objectAtIndex:0] valueForKey:@"v_Ref"]);

    return myIdentity;
}
return nil;
}
