Determining If A "capture" Is Saved To Photo Library?

Audio and Graphics
#1

On iOS,

The first time I use 

local finishedImage = display.capture(finalPic, true)

to capture finalPic into the photo library, I am prompted by a popup asking if I accept or deny the app access to save pictures to the photo library. Based on this, I have two questions:

  1. Is there any way to determine, via a callback or a return or an event or something, which choice the user makes at this point?

  2. Also, on all subsequent attempts to save in this way using the same app, iOS remembers what choice the user initially made. Is there any way I can determine if the picture was saved to the photo library on these subsequent attempts? This is even more important that question 1, since on the first attempt, they obviously know what choice they made, but in all later attempts, I’d like to pop a window to let them know whether or not the picture was saved.

Thanks.
