get the bundle id of app from PID in ios
===

I am trying to get a list of all the background apps currently running on the iphone.
I am able to do so but what I actually get is the a list of all the background app's PIDs.

So I have two questions,

First
I am able to launch an app with its bundle id but not with its PID.
Is launching an app with PID possible?

Second
Is there a way to access the apps bundle id if all i have is its PID?

I understand this can be done on the mac with

    [[NSRunningApplication runningApplicationWithProcessIdentifier:pid] bundleIdentifier]

but can it be done on the iphone?
