Why is my screenshot not displaying current view?

Question

When I take a screenshot to share the current view of my device (iPhone), it only takes the upper part of it, and when I scroll down to the bottom (of my tableview at runtime), the screenshot is blank as if not capturing the current view on the device - I hope I am explaining alright there.

Am I missing anything?

func captureScreen() -> UIImage {

    UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, false, 0);
    self.view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
    let image:UIImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image
}

Not sure if related, but are you aware of the difference between `bounds` and `frame`? It might be that in one of the methods you should use `frame` instead. — luk2302, Apr 25 '16 at 15:52
I think it should be `UIGraphicsBeginImageContextWithOptions(self.view.frame.size, false, 1)` — Khuong, Apr 25 '16 at 15:53
It was indeed a case of replacing `bounds` with `frame`. Thank you, guys! Is there a way to accept your answers? I can't see the checkmark. — Laroms, Apr 25 '16 at 16:08
They are just comments, not answers! Therefore you cannot accept one ;) Glad to help — luk2302, Apr 25 '16 at 16:10

Change your code to the following :

func captureScreen() -> UIImage {

UIGraphicsBeginImageContextWithOptions(self.view.frame.size, false, 0);
self.view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
let image:UIImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

return image

}

Note the change from bound to frame in your code. The last argument in UIGraphicsBeginImageContextWithOptions has to do with the scale. If you specify a value of 0.0, the scale factor is set to the scale factor of the device’s main screen
