使命名错误的选择器产生编译时错误 [英] Making a misnamed selector generate a compile time error
问题描述
在objective-c 中,我怎样才能让一个命名错误的选择器产生一个编译时错误?
In objective-c how can I make a misnamed selector generate a compile time error?
例如,假设我有这个
@selector(some_misnamed_func)
我的班级有这个成员
-(void)some_func
我希望 Objective-c 编译器告诉我它在编译时找不到该函数,而不是仅在运行该代码时才生成运行时异常.
I want the objective-c compiler to tell me that it can't find that function at compile time rather than generate a run-time exception only when that code is run.
推荐答案
在 Xcode 的构建设置中使用 -Wundeclared-selector
或 Undeclared selector 编译您的代码.由于这只是一个警告,您可以将它与 -Werror
(在 Xcode 中分别将警告视为错误)结合起来,使该警告(以及所有其他警告)表现为错误并有效地中止编译.
Compile your code with -Wundeclared-selector
, or Undeclared selector in Xcode’s build settings. Since that’s a warning only, you can couple it with -Werror
(resp. Treat Warnings as Errors in Xcode) to make that warning (and all other warnings) behave as an error and effectively abort the compilation.
