objective c - Suppress warning "Category is implementing a method which will also be implemented by its primary class"

Question

I was wondering how to suppress the warning:

Category is implementing a method which will also be implemented by its primary class.

I have this for a specific code category:

+ (UIFont *)systemFontOfSize:(CGFloat)fontSize {
    return [self aCustomFontOfSize:fontSize];
}

Although everything bneely said is correct, it doesn't actually answer your question of how to suppress the warning.

If you have to have this code in for some reason (in my case I have HockeyKit in my project and they override a method in a UIImage category [edit: this is no longer the case]) and you need to get your project to compile, you can use #pragma statements to block the warning like so:

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-protocol-method-implementation"

// do your override

#pragma clang diagnostic pop
