How to restrict user to purchase new In-App Purchase Product while it is being review by Apple?

No, there is (unfortunately) no interface in iTunes Connect to determine if in-app purchases have passed the review process: you will need to set up an option in your web service that filters out products that have not yet been approved, and then once they pass through the review process you can make them available to the app.

If I do so as you say, then the new products will not be available in my App for Apple also while reviewing. Will Apple approve my In-App Purchase products? – Pankaj 2 days ago Ah.

That one I'm honestly not sure about: I'm assuming they would approve the products but you might want to spend one of your support incidents on verifying that. – Femi 2 days ago Thanks Femi.....if anyone have any idea about it. Please let me know..... – Pankaj 2 days ago.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
