ios - 解码 Storyboard 时出现错误访问崩溃
<p><p>我收到了 2 份崩溃报告，其中回溯似乎表明在 Storyboard 中解码图像引用时出现问题。已在此设备上报告</p>
<p> <img src="/image/YaR31.png" alt="enter image description here"/> </p>
<p>我无法在运行 7.1 的 iPhone 5 或运行 7.0 的模拟器上重现它。我正在使用 7.1 SDK、 Storyboard和 Assets 目录。</p>
<p>第一个日志如下所示:</p>

</code></pre>
<p>任何想法可能导致此问题或我如何调试它？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我想我找到了问题， Storyboard 包含以下标记:</p>
<pre><code><image name="pressed" width="1" height="1"/>
</code></pre>
<p>而实际图像为 1x80 像素。 </p>
<p>可能某些版本的 iOS 信任 Storyboard 并分配大小不正确的缓冲区，而其他版本则执行某种边界检查。</p>
<p>因此，解决方案是检查 Storyboard XML 末尾的 <code><resources></code> 标记是否有不正确的大小。如果有，请删除图像并重新添加它们。如果这不起作用，请完全删除图像，然后将其加载到代码中。</p></p>
