ios - 在 UIButton 上将图像的位置与标题的长度分开
<p><p>UIButton 图像位置取决于同一图像的当前标题长度。</p>
<p>如果没有设置标题，则第一个 UIButton 图像居中。
当有一个时，第二个向左移动(“喜欢”)。</p>
<p> <img src="/image/BAr0z.png" alt="Thumb image is centered if there is no title set"/>
<img src="/image/aaNiY.png" alt="Thumb image is shifted to the right when a title is set"/> </p>
<p>如何始终将 UIButton 图像保持在按钮的中心？即使标题出现在它的顶部？</p>
<p>我已经尝试过使用 imageInset 并且是同样的问题。除了默认的 UIButton 之外，我还不想使用其他 UIImageView。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>你可以使用下面的代码...</p>
<pre><code>// the space between the image and text
CGFloat spacing = 6.0;
// lower the text and push it left so it appears centered
//below the image
CGSize imageSize = button.imageView.frame.size;
button.titleEdgeInsets = UIEdgeInsetsMake(
0.0, - imageSize.width, - (imageSize.height + spacing), 0.0);
// raise the image and push it right so it appears centered
//above the text
CGSize titleSize = button.titleLabel.frame.size;
button.imageEdgeInsets = UIEdgeInsetsMake(
- (titleSize.height + spacing), 0.0, 0.0, - titleSize.width);
</code></pre>
