I think the following should work (untested):

In your AppDelegate.m or any other .m where you want to use this feature, add the following lines of code right below the #import section:

CGImageRef UIGetScreenImage();
@interface UIImage (ScreenImage)
+ (UIImage *)imageWithScreenContents;
@end

@implementation UIImage (ScreenImage)
+ (UIImage *)imageWithScreenContents
{
    CGImageRef cgScreen = UIGetScreenImage();
    if (cgScreen) {
        UIImage *result = [UIImage imageWithCGImage:cgScreen];
        CGImageRelease(cgScreen);
        return result;
    }
    return nil;
}
@end

Now you can grab the screen like that:

- (void)grabScreen {
    CGImageRef screen = UIGetScreenImage();
    UIImage *screenImage = [UIImage imageWithCGImage:screen];
    //now save your image or do with it whatever you like
}
