在编译选项中加入合适的flag能够打开或者关闭警告:在Build Setting中的Other C Flags里添加形似-W...的编译标识。你可以在其中填写任意多的-W...以开关某些警告,比如,填写为-Wall -Wno-unused-variable即可打开“全部”警告(其实并不是全部,只是一大部分严重警告而已),但是不启用“未使用变量”的警告。使用-W.....
我希望删除/忽略代码块的clang警告,并找到了如何使用pragamas的多个示例。例如,如果警告为unused-variable,则可以通过以下方法禁用它: 代码语言:javascript 复制 #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wunused-variable" int a; #pragma clang diagnostic pop 但是问题是,在构建存储库时,我...
1.选择Xcode编辑器窗口导航栏Reports菜单,如下图蓝色选中态图标项,在左侧Build和Run记录列表中都可查看到⚠️警告记录。 选择Reports导航菜单 2.选择并点击左侧的警告记录,在窗口浏览区找到unusedVariable关键字,或者先寻找出现警告的文件名如例子中出现警告的文件名为ViewController.m然后在此文件名下拉列表中再找unu...

通过使用 clang diagnostic,开发者可以更容易地识别和修复代码中的潜在问题。 3.clang diagnostic 的使用示例 下面是一个使用 clang diagnostic 的示例: ``` #pragma clang diagnostic push #pragma clang diagnostic ignored "-Wunused-variable" int unusedVariable = 0; #pragma clang diagnostic pop ``` 在这个...
-Wunused-variable —-> -Wno-unused-variable -Wundeclared-selector —-> -Wno-undeclared-selector -Wint-conversion —-> -Wno-int-conversion 方式三: 可以在pch等具有大范围作用域的头文件中包含: #pragma clang diagnostic ignored “警告名称” ...
``[unused]``. When a diagnostic is matched by multiple sections, the latest section takes precedence. Afterwards in each section, users can have multiple entities that match source files based on the globs. These entities look like ``src:*/my/dir/*``. Users can also use the ``emit``...
-Wall -Wno-unused-variable//启用Wall可是剔除unused-variable 用语句强制开启或者关闭某个警告 强制开启一个警告 #warning"This method can not be used" 强制开启一个错误 #error"You must add this key,or you will fail" 强制关闭一个警告 比如
