Question

I am working with Objective-C in Xcode. I was wondering is there any mechanism to proof your code to make sure all functions and methods are declared in the .h file or in the private @interface method?

To clarify I will be on a coding tangent and will write a method directly in my viewController.m file

- (Awesome*) generateAwesomeOfMagnitude:(NSFloat)magnitude { ...

and I will forget to add the heading to the viewController.h file. If this is a private method nothing notifies me that I’ve done this so I have to go back through and verify that everything was declared manually when Im done. Is there any way to check automatically?

Note: Im looking to make the complier to throw a warning. Is there a setting is really what I should have asked.

Answer 1

To check if method exists at run time in the class use

if([yourObject respondsToSelector:@selector(generateAwesomeOfMagnitude:)])
    //has this method
else
    //does not have this method

but you dont get any warning if you define a method in the .m and dont include it in the .h file

However if another class is accessing a method that is not declared in the .h file you will receive a warning
