Hi, sorry I should have stated that its an opengl view. Searching the
web, I think I have to manually use glReadPixels, which is fine.
After getting the buffer I tried creating a UIImage using:
[UIImage imageWithData:[NSData dataWithBytesNoCopy:...]
But it doesn't work, I guess imageWithData is expecting image data
(i.e. file format), not pixel data. How can I create a UIImage from
pixel data? do I need to go into coregraphics? (e.g. CGCreateImage)?

Take a look at UIGraphicsGetImageFromCurrentImageContext() (or
something like that, don't have the docs handy).

Memo,
While in your iPhone app hold down the power off button then hit
the home button. A picture of the current screen will be added to
your photo album.

Not sure if this is the right place for this, but is it possible
for my app to screengrab what its done and save it to the photo app?
