我在业余时间做一个应用程序，想问你一个问题，我的工作区有 3 个子项目：presentation、domain 和 data，每个都是一个静态框架，有自己的 pod，都非常酷，但是现在我有一个问题，我不知道如何解决。我有几个 firebase 依赖项，其中一些必须在 Presentation 中，而另一些在 Data 中，执行时出现问题，因为它给了我一个错误：

PodsDummy_FirebaseUI 类在 /Users/.../Debug-iphonesimulator/PresentationCleanExample.framework/PresentationCleanExample (0x104ffada0) 和 /Users/.../data/Containers/Bundle/Application/A15FF8B8-7B67-4512-8DFD-04F008175660 中实现/CleanExample.app/CleanExample (0x100c6e288)。将使用两者之一。哪一个是未定义的。

所以我在 FirebaseUI/Storage 的 podspec 中看到的是以下内容： https ://github.com/firebase/FirebaseUI-iOS/blob/master/FirebaseStorageUI.podspec

s.dependency 'Firebase/Storage'
s.dependency 'GTMSessionFetcher/Core', '~> 1.5.0'
s.dependency 'SDWebImage', '~> 5.6'

这让我觉得 cocoapods 没有正确解决依赖 Firebase/Storage。

在此处输入图像描述

问题是这只是我从 Firebase 获得的数千个重复类之一，用于遵循上图。我想有一种方法可以只注入一次 Firebase 依赖项，从而避免类重复，但我不知道如何。

问题

  • FirebaseStorageUI.podspec 文件有问题还是 cocoapods 的限制？

  • 我的 Podfile 错了吗？

最后，我解决了受这篇文章启发的问题https://medium.com/@GalvinLi/tinysolution-fix-cocoapods-duplicate-implement-warning-5a2e1a505ea8因为它让我理解了问题。

如果我理解正确 OTHER_LDFLAGS 是通过重复添加框架。

然后为了避免原始消息问题Class *** is implemented in both，我将所有 pod 安装在目标“CleanExample”中，并从以下文件中删除 OTHER_LDFLAGS 行。

  • Pods-DataCleanExample.debug.xcconfig
  • Pods-DataCleanExample.release.xcconfig
  • Pods-PresentationCleanExample.debug.xcconfig
  • Pods-PresentationCleanExample.release.xcconfig
