How to get rid of the 'undeclared selector' warning

Question

I want to use a selector on an NSObject instance without the need for an implemented protocol. For example, there\'s a category method that should set an error prop

Answer 1

Another option would be to disable the warning with:

#pragma GCC diagnostic ignored "-Wundeclared-selector"

You can place this line in the .m file where the warning occurs.

Update:

It works also with LLVM like this:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wundeclared-selector"

... your code here ...

#pragma clang diagnostic pop
