How to give UITableViewCells a selected color other than gray
Ever since iOS 7.0, table view cells have been gray when tapped, even when you specifically told Interface Builder you wanted them to be blue. Don't worry, though: it's an easy thing to change, as long as you don't mind writing three lines of code. Specifically, you need to add something like this to your cellForRowAt method:
let backgroundView = UIView()
backgroundView.backgroundColor = UIColor.red
cell.selectedBackgroundView = backgroundViewYou can customize the view as much as you want to, but remember to keep the overall amount of work low to avoid hurting scroll performance.
Available from iOS 7.0
