Is all that code “fully app store approved”?

Also, how would I save the screen-shot picture to the camera roll?

If you’re trying to do this on a retina device, you’ll notice your view’s snapshot is captured at half resolution. To fix this, open the context using this instead:

UIGraphicsBeginImageContextWithOptions(gridView.frame.size, NO, 0);

The 0 at the end causes the context to be opened using the device’s correct scale.

Thanks a lot for the tutorial. It helped a lot especially you guilded how to capture a screenshot & use UIImagePNGRepresentation. Highly appreciate

I found a very minor items. You missed out to add a checking. Without that, it will fail to run on the phone which didnt setup the email.

if ( email == nil)
{

NSLog(@”Device not configured to send email”);
return;
}

Can you still use UIGetScreenImage() in 4.2?

Awesome snippet Skylar. One thing is that I’m using this code on an iPad application in landscape orientation and the resulting screengrab is in portrait mode. I know I could just alter the image itself but is there a cleaner way to get the image at the correct orientation?

Good catch, I have not updated the sample code attached to post. Honestly, this is such a simple post that I simply forgot that I had attached any downloadable source code. I will update the download link at some indeterminate date in the future.

Thanks!

did the source attached to the post get updated. I can’t tell, I don’t see any of the lines talked about in the source code. Was there a 3rd change not posted ?
