Exclude View from Screenshot

Question

This is how I take a screenshot of my view:

UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0.0)
view.drawViewHierarchyInRect(view.boun         


        

Answer 1

Oh, actually, just following code (swift 4) can work. That is, create a context, and add the item you want in the snapshot. No need to add view in real screen.

Note: currentView is the view which snapshot based on, commonly, it will be view of whole screen. And addViews are the views you want to add.

func takeSnapShot(currentView: UIView , addViews: [UIView], hideViews: [UIView]) -> UIImage {


    for hideView in hideViews {
        hideView.isHidden = true
    }

    UIGraphicsBeginImageContextWithOptions(currentView.frame.size, false, 0.0)

    currentView.drawHierarchy(in: currentView.bounds, afterScreenUpdates: true)
    for addView in addViews{
        addView.drawHierarchy(in: addView.frame, afterScreenUpdates: true)
    }

    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    for hideView in hideViews {
        hideView.isHidden = false
    }

    return image!
}
