iAd producer / iBook author -- create a "save" button?
hi,
I'm using iAd Producer to create an iBooks Author drawing widget. I would like to create a "save" button that creates a screenshot of the sketch widget and saves the image into the iPhoto gallery. Better yet, I would also like to define the exact area of the widget screen that is used for the screenshot. Some professional widgets, such as those provided by Bookry, have this functionality build into the widget. Bookry's widget also allows one to email the drawing as well.
Could anyone point me in the right direction how to do this? Obviously it's already been done successfully, but I can't figure out how to do this in iAd producer.
Thanks!
