Does any know how to bypass entitlements in iOS 8?

Question

As you aware that the famous _XPConnectionHasEntitlement has no longer works in iOS 8, is there anyother way to bypass the entitlements with the tweaks that requires entitlements? I come to know that _BSAuditTokenTaskHasEntitlement might solve the issue, but I can't get through it.

I'm using following snippet of code to hook into backboardd & assertionsd.

static int (*orig_BSAuditTokenTaskHasEntitlement)(id connection, NSString *entitlement);
static int hooked_BSAuditTokenTaskHasEntitlement(id connection, NSString *entitlement) {
    NSLog(@"Got it.");
    if (xpc_connection_get_pid(connection) == [[UIDevice currentDevice] __qrwaGetPIDForProcess:@"SpringBoard"] && [entitlement isEqualToString:@"com.apple.multitasking.unlimitedassertions"]) {
        return 1;
    } else {
        return orig_BSAuditTokenTaskHasEntitlement(connection, entitlement);
    }
}

%ctor {
          %init;
          MSHookFunction(((int *)MSFindSymbol(NULL, "_BSAuditTokenTaskHasEntitlement")), (int*) hooked_BSAuditTokenTaskHasEntitlement, (int**) &orig_BSAuditTokenTaskHasEntitlement);
}

The problem with it, the NSLog statements never printed. So I feel that something wrong with syntax of the function _BSAuditTokenTaskHasEntitlement, but not sure.

If anyone points me right direction, I appreciate their help.
