How to disable warning: Using 'stringWithString' with a literal is redundant?

Question

Some old third party code gives warning:

Using 'stringWithString' with a literal is redundant

Instead of modifying the source codes, I'd prefer to disable the warning in Xcode. What is the compiler switch to disable this specific warning?

Why don't you want to modify the source? The use of stringWithString is hardly ever merited. — Hot Licks, Oct 18 '13 at 07:40
Or, if you refuse to modify the source, perhaps the warning should be left there, to flag this poor practice for future maintenance. — Hot Licks, Oct 18 '13 at 14:47

The warning message should tell you the name of the warning. You can then turn that warning off.

test.m:4:5: warning: using 'stringWithString:' with a literal is redundant 
      [-Wobjc-redundant-literal-use]

so you want to add the flag -Wno-objc-redundant-literal-use to the compiler flags for that file or that project.

That's an extreme. Disabling all warnings is not something he should do. – Léo Natan Oct 18 '13 at 03:37

But the OP insists on not modifying the source, so only the global flag will work. – Hot Licks Oct 18 '13 at 14:48
