<p><p>好的，我以任何方式发布链接答案的快速版本，类似于您的要求。</p>
<p>你可以像下面那样做，只需创建一个渐变层，你想要的颜色分布在渐变层上，最后将渐变设置为 ImageView ，例如</p>
<pre><code>@IBOutlet weak var aImageView: UIImageView!
var theColor: UIColor?
var gradientLayer:CAGradientLayer?
override func viewDidLoad()
{
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.theColor = UIColor(colorLiteralRed: 146.0/255.0, green: 146.0/255.0, blue: 146.0/255.0, alpha: 1)
self.gradientLayer = CAGradientLayer()
self.gradientLayer?.frame = self.aImageView.frame
let array: = [(theColor?.colorWithAlphaComponent(0.1))!.CGColor,
(theColor?.colorWithAlphaComponent(0.12))!.CGColor,(theColor?.colorWithAlphaComponent(0.13))!.CGColor,
(theColor?.colorWithAlphaComponent(0.74))!.CGColor,
(theColor?.colorWithAlphaComponent(0.82))!.CGColor,
(theColor?.colorWithAlphaComponent(1.0))!.CGColor]
gradientLayer?.colors = array;
aImageView.layer .addSublayer(gradientLayer!);
}
</code></pre>
<p>尝试放入示例项目，结果将如下所示</p>
