Apply gradient to UIButton iOS swift

-

 Solution:

extension UIButton {

    func applyGradient(colors: [CGColor]) {

        let gradientLayer = CAGradientLayer()

        gradientLayer.colors = colors

        gradientLayer.startPoint = CGPoint(x: 0.5, y: 0)

        gradientLayer.endPoint = CGPoint(x: 0.5, y: 1)

        gradientLayer.frame = self.bounds

        self.layer.insertSublayer(gradientLayer, at: 0)

    }

    

}


extension UIButton {

    func setBlackGrdient() {

        self.applyGradient(colors: [UIColor().colorWithHexString(hexString: "#252525").cgColor, UIColor().colorWithHexString(hexString: "#4e4e4e").cgColor])


    }

    

    func setWhiteGrdient() {

        self.applyGradient(colors: [UIColor().colorWithHexString(hexString: "#f4f4f4").cgColor, UIColor().colorWithHexString(hexString: "#b6b6b6").cgColor])


    }

}


The above function we can create button with black gradient using setBlackGrdient() function.


Also if you want to create with white gradient then use setWhiteGrdient() function
