Code example for iPhone UIGetScreenImage

Question

I've seen a number of posts on UIGetScreenImage, however, not a complete working (short) code example.

If anyone has a code example, from the prototype definition to an actual call, that would be greatly appreciated.

Thanks

John

Answer 1

CGImageRef UIGetScreenImage(void);

....

    CGImageRef screen = UIGetScreenImage();
    UIImage* screenImage = [UIImage imageWithCGImage:screen];
    CGImageRelease(screen); // you need to call this. 
                           // UIGetScreenImage violates the CF memory management rules.
    // Use screenImage as you like.
