Xcode Build and Analyze - Is it possible to purposely skip analysis on a particular file?
提问by Cruinh
I have one particular file in my project which is being worked on by someone else. I don't want to mess with it and would rather not wait for "Build and Analyze" to process it. Is there a way to tell Xcode to skip analysis on this file?
我的项目中有一个特定文件正在由其他人处理。我不想弄乱它，也不想等待“构建和分析”来处理它。有没有办法告诉 Xcode 跳过对这个文件的分析？

If it's OK to edit the file, there's a brute force option.
如果可以编辑文件，则有一个蛮力选项。
Add this to the beginning of the file:
将此添加到文件的开头：
// Omit from static analysis.
#ifndef __clang_analyzer__
Add this to the end:
将此添加到最后：
#endif // not __clang_analyzer__
and the clang analyzer won't see the contents of the file.
并且 clang 分析器不会看到文件的内容。

Same idea as this answer only for analysis -> Ignore all warnings in a specific file using LLVM/Clang
与此答案相同的想法仅用于分析 ->使用 LLVM/Clang 忽略特定文件中的所有警告
You can include a "compile sources" argument in the "Build Phases" tab of the project settings to ignore a specific file from the analyzer. Here are some instructions:
您可以在项目设置的“构建阶段”选项卡中包含“编译源”参数以忽略分析器中的特定文件。以下是一些说明：
- Select the target for the project you want to change.
- Select the build phase tab.
- Expand the "Compile Sources" menu.
- Find the file to edit.
- Double click its "Compiler Flags" cell to change the arguments.
- Add
-Xanalyzer -analyzer-disable-checker, or-Xanalyzer -analyzer-disable-all-checksfor Xcode 10 and after - Optionally add
-Wno-unused-command-line-argumentas well, if Xcode complains that-Xanalyzeris unused during regular compiles and you want to keep your build clean
- 为要更改的项目选择目标。
- 选择构建阶段选项卡。
- 展开“编译源”菜单。
- 找到要编辑的文件。
- 双击其“编译器标志”单元格以更改参数。
- 添加
-Xanalyzer -analyzer-disable-checker, 或-Xanalyzer -analyzer-disable-all-checksXcode 10 及之后 - 也可以选择添加
-Wno-unused-command-line-argument，如果 Xcode 抱怨-Xanalyzer在常规编译期间未使用并且您希望保持构建干净
Note: adding -w will also disable warnings on a particular file as well.
注意：添加 -w 也会禁用特定文件的警告。
