在静态库中，Xcode 8.1不会检测何时未实现Objective-C方法 [英] In a static library, Xcode 8.1 does not detect when an objective-c method is not implemented

问题描述

我的Objective-C项目使用一个静态库，最近我才发现Xcode 8.1并未对该库发出一些警告。
当应用程序本身缺少方法实现时，我会收到警告。但是，如果库中缺少方法实现，则不会收到任何警告。它只是在运行时崩溃。

My objective-c project uses a static library and recently I just discovered that Xcode 8.1 does not give some warnings for the library. When a method implementation is missing in the app itself, I get a warning. But if a method implementation is missing in the library, I get no warning. It just crashes at run time.

与带有枚举的switch语句相同。如果缺少某个案例，Xcode会发出警告，但不会在静态库中发出警告。

Same for the switch statement with an enum. If a case is missing, Xcode would signal a warning, but not in the static library.

在以前版本的Xcode中，我确定我在我的库中收到了这些警告。而且我从未更改任何构建设置，而只是保留所有默认值。

In previous versions of Xcode, I am sure I received those warnings in my library. And I never changed any Build Settings, I just keep all the default values.

更多信息：

当我将静态库本身作为项目打开时，会收到所有警告。但是，当我打开另一个包含库的项目时（我将mylibrary.xcodeproj文件拖放到了项目中，并在链接阶段添加了它），我没有库警告

When I open the static library itself as a project, I get all warnings. But when I open another project that includes the library (I dropped the mylibrary.xcodeproj file in my project and add it in the Link phase), I don't have the library warnings

推荐答案

这是Xcode中的错误。现在，它在Xcode 8.3版（8E162）中运行良好

It was a bug in Xcode. It is now working well in Xcode Version 8.3 (8E162)
