ios - iOS 上更强的阴影
<p><p>我正在尝试用一些发光效果为按钮设置动画。</p>
<p>到目前为止，这是我得到的:</p>
<pre><code>self.glowLayer = [ init];
self.glowLayer.contents = (__bridge id _Nullable)(self.currentBackgroundImage.CGImage);
self.glowLayer.opacity = 0; // set to 1 with animation.
self.glowLayer.shadowColor = .CGColor;
self.glowLayer.shadowOffset = CGSizeZero;
self.glowLayer.shadowRadius = 5;
self.glowLayer.shadowOpacity = 1;
self.glowLayer.rasterizationScale = .scale;
self.glowLayer.shouldRasterize = YES;
;
</code></pre>
<p>但是，我发现发光效果不够强。
当然，我可以更改阴影半径以使其更宽，但这只会使阴影“稀释”而不是变得更强。</p>

<p>我应该如何进行？</p></p>

<p><p>改变值
self.glowLayer.shadowOpacity 1 将为您工作。
并尝试 Translucent = No</p></p>
