Have you tried subclassing the UIView as a UIControl?
I had a similar issue but in my case the view for UITargetedPreview was glitchy. However, changing the UIView to a UIControl fixed everything.

There is a tricky method to hide the shadow and to do that you should find a view with <code>_UIPlatterSoftShadowView</code> class name in the view hierarchy and then hide it.
<pre class="lang-swift prettyprint-override"><code>func viewByClassName(view: UIView, className: String) -&gt; UIView? {
 let name = NSStringFromClass(type(of: view))
 if name == className {
 return view
 }
 else {
 for subview in view.subviews {
 if let view = viewByClassName(view: subview, className: className) {
 return view
 }
 }
 }
 return nil
}

override func tableView(_ tableView: UITableView, willDisplayContextMenu configuration: UIContextMenuConfiguration, animator: UIContextMenuInteractionAnimating?) {
 DispatchQueue.main.async {
 if let window = UIApplication.shared.delegate?.window! {
 if let view = self.viewByClassName(view: window, className: &quot;_UIPlatterSoftShadowView&quot;) {
 view.isHidden = true
 }
 }
 }
}
</code></pre>
NOTE: It's not documented internal class and can be changed anytime further but it works now on both ios 13/14.

You need to study UIBezierPath() to outline the specific area you want to enclose before you present the target view.
After that, you shall assign the specific path to shadow path / visible path
<pre><code>let params = UIPreviewParameters()
 params.backgroundColor = .clear
 if #available(iOS 14.0, *) {
 params.shadowPath = bubblePath
 } else {
 params.visiblePath = bubblePath
 }

 
</code></pre>

I'm trying to remove the background view for my <code>UITargetPreview</code>. I made the background color clear, however, you can still see the frame of the background.
This is what it currently looks like:
<a href="https://i.stack.imgur.com/NF1cu.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/NF1cu.jpg" alt="" /></a>
I currently have a view that has the text container and the image inside of it and that's what I use as the view for the <code>UITargetedPreview</code>.
Is there a way to only show the image and the text and not the background frame?

我正在尝试删除我的UITargetPreview的背景视图。我把背景颜色弄清楚了，但是，你仍然可以看到背景的框架。这就是目前的样子：​​我目前有一个视图，其中包含文本容器和图像，这是我作为UITargetedPreview视图使用的。有没有一种方法只显示图像和文本，而不是背景框架？
