Block the call from specific number in iphone [duplicate]

Can an iPhone app block phone calls?

Closed 9 years ago.
I want to block the phone call from the particular phone numbers. Is this possible?
I had searched and found this link :-
Block phone call post
But I don't get the exact idea whether it is possible or not?
The Exact & Clear Idea is that
It is not possible to block call from particular number in iOS Until and unless you have an jailbreaked iOS Device.
Without creating an app via jailbreak, or using private libraries at the very least, you won't be able to do this. The usage of private libraries in an app will end up with your App Store submission being denied.
It's Possible....
Short Answer : It's not possible with Straight Way. That doesn't mean there are no other Ways. Check this :

Long Answer : Refer the Accepted Answer Here : How can I use private APIs to block incoming calls in an iOS application?

I am an iPhone devleoper.
I want to record the conversation during phone call.
I don't know apple is allowing to do this or not.
If yes, than can anybody guide me how can i do this?
Basically In my app ,I am recording 1 audio .
Now when i call someone from my contact ,I want to play that audio as well as record the conversation.
Both play and record thing I want.
I am confused whether it is possible or not.
There is no public API for recording the calls made (or received) by the built-in Phone app.
You will have to implement your own phone calling mechanism. You'll probably want to use VoIP. (That is what Google Voice uses, for example.) You'll need to run your own server on the Internet, or contract with an existing VoIP service. You'll want to use in-app purchase to let the user buy minutes, because it costs money to run your own server or use a third-party service.
There is no public API for this. No app headed for the App Store can record phone calls made with the standard Phone app.

Is it possible to get GPS satellite numbers via iPhone SDK ?
I am looking for the equivalent of LocationManager.getGpsStatus(...) on Android (link). More precisely it would be interesting to get, for all tracked satellites: their PRN numbers, C/N0, azimuths and elevations.
I know the SDK does not have any such interface, but does anyone know of a possible way to access to these values, or any software project showing such information?
There is no public available API that allows you to get this kind of detailed information about the GPS satellites.

Aside from using URL scheme, what other means are there for two iPhone apps to pass data between each other (ideally, without launching another app -- which is one of the downsides using URL scheme)
Unfortunately apps are sandboxed, and can't communicate with each other. You would have to implement something server-side to act as a central location for this data.
