UIRefreshControl Background Color

Question

Is it possible to make the background of a UIRefreshControl grow as the control grows?

I would like to have a colored background for the refresh control to match the top

Answer 1

This can now be achieved (Swift 5, iOS 13) by simply setting the UIRefreshControl background color property:

let ctrl = UIRefreshControl(frame: .zero)    
ctrl.backgroundColor = UIColor.gray'
tableView.refreshControl = ctrl
