How to convert UIScrollView to image?

Question

I have a scrollview, frame size is 480x265 and content size is 1800x600.

I have a lot of UIView added as a subview to this scrollview.

May I know how should I be able to convert this scrollview to an image?

Many thanks for any comments/help in advance!

- (void)submitClicked
{
     UIGraphicsBeginImageContext(scrollView.contentSize);

     CGPoint savedContentOffset = scrollView.contentOffset;
     CGRect savedFrame = scrollView.frame;

     scrollView.contentOffset = CGPointZero;
     scrollView.frame = CGRectMake(0, 0, scrollView.contentSize.width,  scrollView.contentSize.height);
     [scrollView.layer renderInContext: UIGraphicsGetCurrentContext()];     
     UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

     scrollView.contentOffset = savedContentOffset;
     scrollView.frame = savedFrame;

     UIGraphicsEndImageContext();
}

Seems like you want to save the content of your scroll view to image.

UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * data = UIImagePNGRepresentation(image);
[data writeToFile:@"myImage.png" atomically:YES];

This will only capture the visible portions of the scrollview and it will clip the rest of the contents that are not visible – iwasrobbed May 30 '13 at 03:11
