stop sms messaging to iPhone programmatically

问题:

I want to confirm a feature, a client asks to me develop an app with a feature that it is able to stop sms messages to the phone for a certain period of time. I have done some research and found a link pasted below (and the screen shot of the page) in which the author of a renown iPhone App development book states it is not possible. What's your take on this?

Core Telephony framework lets us get the notification when a call and sms is received but I couldn't find a way we can stop it.

回答1:

You probably can do it on a jailbroken device. You might be able to do it in a private framework (but it's pretty unlikely). It probably wouldn't be allowed in the App Store.

回答2:

You can't stop it, they were right.
