ios - 将 iOS 框架作为文件或 pod 分发

Question

我尝试从客户端添加一个我们必须在我们的产品中使用的框架，并将其作为文件分发。

我面临的问题是该框架不适用于模拟器，当我想使用模拟器时，我必须使用框架的调试版本。但是我们发布到应用商店时不能包含调试版本，他们说会被拒绝。

当我用谷歌搜索这个问题时，看起来苹果不允许这种框架。还是最近有所改变？

我还找到了有关所谓的 FAT 框架的信息，这是新的东西吗？

我试图在 apple.com 上找到有关此的信息，但我没有找到任何可以解释这种情况的信息。

当我使用像 Firebase 这样作为 pod 分发的框架时，我没有这个问题。

这些框架之间有什么区别？
客户端可以使用框架做些什么，以便可以在模拟器和应用商店中使用它？

Answer 1

When I google this problem, it looks like Apple does not allow this kind of frameworks. Or has this been changed lately?

它的工作方式是 Apple 不允许将模拟器二进制文件(x86_64 和 i386)上传到应用商店。

I also find information about so called FAT frameworks, is that something new?

FAT 框架并不是什么新鲜事。它们基本上是 FAT 二进制文件的包装器。 FAT 二进制文件包含多个体系结构。

When I use a framework like Firebase that is distributed as pod I don't have this problem.

它们没有这个问题，因为它们是作为 Pod 分发的。这些框架具有 FAT 二进制文件，即同时包含设备(armv7、arm64)和模拟器(i386、x86_64)。然后真正的魔法发生在 Cocoapods 的末端。 Cocoapods 使用构建时脚本来去除不必要架构的二进制文件。

您可以使用 cocoapods 使用的相同脚本对您的框架执行相同的操作:)

只需将您的框架传递给 install_framework 方法，如下所示:

install_framework "$BUILT_PRODUCTS_DIR/BadgeSwift/BadgeSwift.framework"
