Iphone compile warning

im compiling my app , which is working great and i wanted to ask you 2 questions 1. im getting about 14 warnings like that

no '-addCategory' method found

which i know how to solve but even after i cleaned everything added the function to the header file and compile again it's still there i cant get rid of it. 2. im pretty new in coding and the code is not GREAT but it's ok h开发者_如何学Cow do i know apple will accept it ?

thank you very much !!

Declare that method in .h file
Implement that method in .m [implementor of .h] file .with the same signature.
Clean in once.
And try.. It should work..!
