horizonView.layer.insertSublayer(gradient, at: 0)


// グラデーションから色を変更したい時は、下記のようにlayerをhiddenにする
for layer in horizonView.layer.sublayers! {
　　　　if layer.name == "gradationLayer" {
  　　　　layer.isHidden = true
  }
}

텍스트로 설정

let gradationImage = UIImage(named: "GradationImage")!
gradationTextLabel.textColor = UIColor(patternImage: gradationImage)
