Is it possible to set backgroundColor = .clear to a LNPopupCustomBarViewController?

I've tried like this but down't work:

`class CustomPopupBarVC: LNPopupCustomBarViewController {

override func viewDidLoad() {
    view.backgroundColor = .clear
}

}`

It should be possible. Use LNPopupBarAppearance.

let appearance = LNPopupBarAppearance()
appearance.configureWithOpaqueBackground()
appearance.backgroundColor = .clear

containingPopupBar.standardAppearance = appearance

Check also what’s going on with the _LNPopupBarContentView and _LNPopupBarBackgriundView, and their respective visual effect views.

It's interesting, the UIView inside _LNPopupBarContentView has the background color I see.
All the other views are correctly transparent. I should try to reach that UIVIew and set it transparent.

Also see the alpha of that view. If it is 0, the color doesn’t matter. I think that view is the highlight view, when the user touches the bar.

[RiccardoManoni]

I've understand now. There is nothing wrong with the background color. It works, it is transparent.

The problem is that I expected that the collection's viewcells should have been scroll behind the customPopupBar, but this reasoning seems to be wrong.

Do you agree with me?

That expectation is not wrong. The content under should go under the popup bar. I’m not sure how you have set up your view hierarchy.
