Question

My problem is this –

I have a UIImageView which a user can rotate freely.

I would now like to be able to capture just this newly rotated image.

The code below, which can take a screenshot of an individual view, unfortunately returns
a screenshot of the view in its unrotated state.

-(IBAction)captureScreen:(id)sender
{
    UIGraphicsBeginImageContext(imgView.frame.size);
    [imgView.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *screenshot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(screenshot, nil, nil, nil);
}

Any ideas how can I retain the rotation here?

Answer 1

Use your code on a view containing the rotated view not on the rotated view itself.
