Change Background Color of multiple UIButton in Single Click

Question

I have 16 UIButton in a UIViewController and only one need to be selected at a time.

I have created a UIButton collection and changing backgroundColor by performing the for loop . It's working fine.

But I need a quick solution in one / two line or I can say the efficient way to change color in a single click.

I don't think my way is efficient because what if the UIViewController has 50 UIButton .

PS Don't tell me to take UICollectionView as I can easily do with that!

Answer 1

You will anyway need enumerate your buttons. But you can do this once in extension:

extension Array where Element: UIButton {
    func setBackgroundColor(color: UIColor) {
        for element in self {
            element.backgroundColor = color
        }
    }
}
