Reload a UITableView while preserving selections and style

Forums > Swift

Hi, i have a tableview with 3 cells, I need to update my tableview, at the moment I am using reloadData, but I would like to save the cell selection when the tableview is closed and then reopened, I would also like to save the style of that cell, that is the background color etc.

    override func viewWillAppear(_ animated: Bool) {

I found this article by Paul, and I'm using it now: https://www.hackingwithswift.com/example-code/uikit/how-to-reload-a-uitableview-while-preserving-selections But when I reopen the tableview it is selected but without the default style that I want, for example with a purple background. How could I solve this? thank you
