我们在 Unity 游戏中使用 Fabric 和 Crashlytics，在使用 Unity 构建 iOS 项目并在 Xcode 中启动后，我们收到大约 26 个错误：

知道如何解决这个问题吗？我检查了 Unity 中的文件，似乎一切都正常导入。

【问题讨论】：

可以是任意数量的东西。我会从这个开始。 stackoverflow.com/questions/6429494/…
检查了“Link Binary With Libraries”以及“Build Phases”以及那里建议的其他一些解决方案，但根本没有帮助。

【解决方案1】：

通过在 Unity 中重新导入整个 Fabric SDK 以某种方式修复它 - 因此删除项目中有关 Fabric 和 Crashlytics 的所有文件，然后再次导入 Fabric。

谢谢，这解决了我的问题。
