ios - Crashlytics 手动更新到 3.8.4 导致链接器错误
<p><p>我有一个非常古老的遗留项目(从 2010 年开始约会)。它的 Crashlytics 套件最后一次更新是在 2013 年的某个地方。</p>
<p>我正在尝试更新它。它不使用 pod，所以我使用了 <a href="https://fabric.io/kits/ios/crashlytics/update?type=manual" rel="noreferrer noopener nofollow">official Manual update</a>指导。</p>
<ol>
<li>我下载了更新的套件。 </li>
<li>按照建议用新的 Crashlytics 替换旧的 Crashlytics。旧的没有 Fabric 工具包，所以我只是将它粘贴在那里并在项目设置中链接库。 </li>
</ol>
<p>这些是这里描述的仅有的两个步骤。但是这样做会导致链接器错误:</p>

<p>我尝试过的事情:</p>
<ol>
<li>删除 Crashlytics 和 Fabrics 的两个引用并重新链接它们。 </li>
<li>删除两个套件的物理实例并读取它们。 </li>
<li>清理 XCode 的派生数据。 </li>
<li>清理项目。 </li>
<li>通过 Cocoapods 安装最新版本。</li>
<li>通过 Fabric 应用升级</li>
</ol>
<p>但错误仍然存在。现在，我束手无策。有关如何解决此问题的任何想法？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我想通了。 </p>
<p>问题是，前一个人修改了链接器和编译器标志，并从中删除了 <code>$(inherited)</code> 标志，该标志覆盖了 Cocoapods 配置，从而导致无法将主项目与Cocoapods 并因此缺少符号，因为 XCode 在没有链接的情况下找不到符号。 </p>
<p>首先我删除了手动 Crashlytics，然后通过 cocoapods 安装了它们。现在它说缺少符号。 </p>
<p>解决这个问题:</p>
<ol>
<li>转到“预处理器宏”并确保将 <code>$(inherited)</code> 添加到调试和发布配置中。 </li>
<li>转到“其他链接器标志”并确保在此处也添加了 <code>$(inherited)</code> 标志。 </li>
</ol>
<p>Crashlytics 3.8.4 现已启动并运行。 </p></p>
