Capture the entire contents of a UITableView or UIScrollView

gistfile1.m

static UIImage* CreateImageFromView(UITableView *view)
{
  UIGraphicsBeginImageContextWithOptions(CGSizeMake(view.contentSize.width, view.contentSize.height), NO, 0.0f);    
  CGContextRef context = UIGraphicsGetCurrentContext();
  CGRect previousFrame = view.frame;
  view.frame = CGRectMake(view.frame.origin.x, view.frame.origin.y, view.contentSize.width, view.contentSize.height);
  [view.layer renderInContext:context];
  view.frame = previousFrame;
  UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();
  return image;
}

To swift 4.0

func createImage() -> UIImage{
        
        UIGraphicsBeginImageContextWithOptions(CGSize(width: contentSize.width, height:  contentSize.height), false, 0.0)
        let context = UIGraphicsGetCurrentContext()
        let previousFrame = frame
        
        frame = CGRect(x: frame.origin.x, y:  frame.origin.y, width: contentSize.width, height: contentSize.height)
        layer.render(in: context!)
        
        frame = previousFrame
        
        let image: UIImage = UIGraphicsGetImageFromCurrentImageContext()!
        
        UIGraphicsEndImageContext()
        
        return image;
    }

wonderful !!!

@aliamcami: If I use the given code it calculates table view's contentsize correctly but fails to load contents of tableview/scrollview.

Hey @iPhoneNoobDeveloper can you try this?

 public extension UIScrollView {
     public var snapshot: UIImage? {
         UIGraphicsBeginImageContextWithOptions(contentSize, false, 0)
         defer {
             UIGraphicsEndImageContext()
         }
         guard let context = UIGraphicsGetCurrentContext() else { return nil }
         let previousFrame = frame
         frame = CGRect(origin: frame.origin, size: contentSize)
         layer.render(in: context)
         frame = previousFrame
         return UIGraphicsGetImageFromCurrentImageContext()
     }
 }

Hi @aliamcami, I want to take a screenshot of the full content of tableview. I tried your code above but the rest of the content that doesn't fit on the screen if getting cut off. (In white in the bottom)

Do you know why? Tks

All content which is not rendered at bottom of table can not be captured. You just captured what was rendered in the screen.
