ios - UIImageView 的图层边框可见插图
<p><p>刚刚这样做:</p>
<pre><code>self.imageView.backgroundColor = color1;
self.imageView.layer.masksToBounds = YES;
self.imageView.layer.borderColor = color1;
self.imageView.layer.borderWidth = 3.0;
</code></pre>
<p>这是问题的截图:</p>
<p> <img src="/image/tCkju.png" alt="Screenshot of a problem"/> </p>
<p>我可以看到图片、边框和图片片段超出边框...</p>
<p> <img src="/image/iG3hq.png" alt="enter image description here"/>
<img src="/image/MXywd.png" alt="enter image description here"/> </p>
<p>我该如何解决？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我在使用图层上的边框属性时遇到了类似的问题，并设法通过在顶部添加 CAShapeLayer 来解决它。<br/>
我无法告诉您它在旧设备上的表现如何，因为尚未使用许多动画等对其进行测试，但我真的怀疑它会减慢它们的速度。</p>
<p>以下是 Swift 中的一些代码:</p>
<pre><code> imageView.backgroundColor = UIColor(red: 0.1137, green: 0.2745, blue: 0.4627, alpha: 1.0)
imageView.layer.masksToBounds = true
imageView.layer.cornerRadius = imageView.bounds.height / 2.0
let stroke:CAShapeLayer = CAShapeLayer()
let rect = imageView.bounds
let strokePath = UIBezierPath(roundedRect: rect, cornerRadius: imageView.bounds.height / 2.0)
stroke.path = strokePath.CGPath
stroke.fillColor = nil
stroke.lineWidth = 3.0
stroke.strokeColor = UIColor(red: 0.1137, green: 0.2745, blue: 0.4627, alpha: 1.0).CGColor
stroke.frame = imageView.bounds
imageView.layer.insertSublayer(stroke, atIndex: 1)
</code></pre>
<p>希望它也适用于您的情况</p></p>
