添加 Crashlytics 和 Fabric 后，出现重复符号链接器错误

Question

我正在pod文件中添加Fabric和Crashlytics。当我更新pods时，我会收到链接器错误，指出有重复的符号。我发现Fabric.framework和Crashlytics.framework中都有相同的文件，但我该如何从我的角度解决这个问题？

Answer 1

1.移除（并将其移到垃圾桶中）Fabric.framework以及任何安装的Fabric kits及其相关资源。

2. 在项目中进行“清洁”和“深度清洁”（ALT-SHIFT-CMD-K）

3. 将Fabric pod添加到您的Podfile中：pod 'Fabric'

4. 为项目使用的每个Fabric kit在Podfile中添加一个pod：pod 'Crashlytics'

注意：如果您需要Crashlytics和Answers，则应仅安装pod 'Crashlytics'，因为Answers已包含在Crashlytics中。如果要使用Answers而不是Crashlytics，请仅安装pod 'Answers'。

希望这解决了您的问题。如果所有这些都失败了，请尝试按照顺序删除所有pod并重新添加它们。 祝您好运！

移除答案 pod 对我很有帮助！感谢 George！ - Lazar Nikolov

谢谢您！Fabric.io页面上说要添加两个。 - Armand
