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\"

Here's updated code for Swift 4 with a few safety checks.

extension UIImage {
    func image(withTint tint: UIColor) -> UIImage? {
        guard let cgImage = cgImage else {
            return nil
        }

        UIGraphicsBeginImageContextWithOptions(size, false, scale)
        guard let context = UIGraphicsGetCurrentContext() else {
            return nil
        }

        let rect = CGRect(origin: .zero, size: size)

        context.translateBy(x: 0, y: size.height)
        context.scaleBy(x: 1.0, y: -1.0)
        context.setBlendMode(.normal)
        context.clip(to: rect, mask: cgImage)
        tint.setFill()
        context.fill(rect)

        let image = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        return image
    }
}
