UIImage animationImages tint color?

Question

Is there a way to tint the images in an animation?

I know I can tint a single image like this:

var imageOne:UIImage = UIImage(named: \"pullto_1.png\"

Maybe this example extension helps:

 extension UIImageView {

        func pulsingTintColor() {
            UIView.animate(withDuration: 2, delay: 0.0, options: [.repeat, .autoreverse], animations: {
                         self.tintColor = UIColor.red
                         self.tintColor = UIColor.green
                         self.tintColor = UIColor.blue
            }, completion: nil)
        }
    }

Ensure you have set the Render as: Template Image option in your asset catalog. This works for UIViews as well. Just replace tintColor with backgroundColor.

If you need parametrised colours:

func pulsingTintColor(with colors: [UIColor] = [UIColor.red, UIColor.green, UIColor.blue]) {
    UIView.animate(withDuration: 2, delay: 0.0, options: [.repeat, .autoreverse], animations: {
         colors.forEach({self.tintColor = $0})
    }, completion: nil)
}
