IPhone : How to send sms programatically in background without open sms popup?

I want to send SMS functionality in background without open popup for SMS

any framework or SDK for that

I have used CTMessageCenter (CoreTelephony Framework) but not working

code:

BOOL success =  [[CTMessageCenter sharedMessageCenter] sendSMSWithText:@"test 1234..." serviceCenter:nil toAddress:@"+1234567890" withMoreToFollow:NO];

    if(success){
        NSLog(@"Message SENT");
    }else{
        NSLog(@"Message not SENT");
    }

any other way then pls let me know.
