Yes.

Whether on StackOverflow or the Apple forums, you'll get a better response if you post a specific question with technical detail, describe what you tried, the results you got, and how they differ from what you want. Open-ended "help me" questions do not usually elicit useful answers, because we don't know what the problem is.
