I'm trying to add a 50% black alpha view on every collection view cell. The collection view cells have a background photograph and text on top. Would like the overlay view to be in between the two.
In my cellForItemAt method, I use the following:
let overlayView = UIView()
overlayView.backgroundColor = UIColor(red: 0, green: 0, blue: 0, alpha: 0.5)
overlayView.frame = cell.bounds
cell.addSubview(overlayView)
The problem is as i scroll down, then up, the overlay keeps adding, making the alpha much darker than 50%. Additionally, the overlayView is being added on top of my text (I need it below the text.)
How can I prevent the overlay from adding multiple times, and adding it in between the correct layers of the cell?
