Does Appframework.grabWindowToFile work in iOS?

[JosephHunt]

I'm trying capture the screen in iOS but it's failing.  On the desktop it works fine.  I'm using 

path = AppFramework.standardPaths.defaultFolder(StandardPaths.PicturesLocation).path;
to set the file location.

I got it. I had made some mistakes with the paths in iOS.
