标题: ios - Crashlytics 手动更新到 3.8.4 导致链接器错误

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。

我正在尝试更新它。它不使用 pod,所以我使用了 official Manual update指导。

  1. 我下载了更新的套件。
  2. 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。

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:

我尝试过的事情:

  1. 删除 Crashlytics 和 Fabrics 的两个引用并重新链接它们。
  2. 删除两个套件的物理实例并读取它们。
  3. 清理 XCode 的派生数据。
  4. 清理项目。
  5. 通过 Cocoapods 安装最新版本。
  6. 通过 Fabric 应用升级

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?



Best Answer-推荐答案


我想通了。

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 $(inherited) 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。

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。

解决这个问题:

  1. 转到“预处理器宏”并确保将 $(inherited) 添加到调试和发布配置中。
  2. 转到“其他链接器标志”并确保在此处也添加了 $(inherited) 标志。

Crashlytics 3.8.4 现已启动并运行。
