iPhone: Get camera preview

Question

I\'d like to get the image that is being displayed on the UIImagePickerController when user uses the camera. And when I get I want to process the image and display instead

Answer 1

The unofficial call is:

UIGetScreenImage()

which you declare above the @implementation as:

extern CGImageRef UIGetScreenImage();

There may be a documented way to do this in 3.1, but I'm not sure. If not, please please file a Radar with Apple asking them to make some kind of screen grab access public!!!

That uses your same AppleID you log in to the iPhone development portal with.

Update: This call is not yet documented, but Apple explicitly has given the OK to use it with App Store apps.
