X和Y都实现了类X.将使用两者之一 [英] Class X is implemented in both Y and Z. One of the two will be used

问题描述

我有一个Objective-C工具"(控制台)程序，该程序在运行时动态加载Objective-C软件包.某些捆绑软件文件共享来自同一框架的类，因此我将类同时在...中实现"消息转储到控制台.

I've got an objective-c "tool" (console) program that dynamically loads objective-c bundle's at runtime. Some of the bundle files share classes from the same framework so I get the "Class is implemented in both..." message dumped out to the Console.

这不会阻止任何操作，但是在控制台上显示消息有些烦人.有没有办法防止它们被扔在那里?有没有一种方法可以更改捆绑软件，以便它们都不编译/链接相同的类?

It doesn't prevent anything from working, but having the messages on the console is somewhat annoying. Is there a way to prevent them from being dumped out there? Is there a way that the bundle's could be changed so they don't both compile/link the same classes?

推荐答案

• 如果它们是不同的实现，请使用唯一的前缀.

  • If they are different implementations, use a unique prefix.

    如果它们是相同的实现，并且只是由多个图像导出，请重新配置目标，使其仅由一个图像导出.

    If they're the same implementation and just exported by more than one image, reconfigure your targets so it's exported by only one.

    特别是:

    有没有一种方法可以更改包的类，使它们不都编译/链接相同的类?

    Is there a way that the bundle's could be changed so they don't both compile/link the same classes?

    将这些共享类填充到一个单独的框架中，不要将它们作为捆绑软件的一部分进行编译-只需将捆绑软件链接到共享内容的框架即可.

    Stuff those shared classes in a separate framework, and do not compile them as part of the bundle -- just link the bundle to the framework of shared stuff.
