xCode / declaring Static Methods in class

Question

Anyone know how I can declare a static method for an xcode class and then use it in my project?

I want to create a Common.h class and then do something like this in one of .m file

Common.MyStaticMethod();

I dont want to have to instantiate and instance of Common

Answer 1

You will declare a class level method in Objective-C by using "+" before the method declaration.

// in Common.h
+ (void)myStaticMethod;

// call is from anywhere
[Common myStaticMethod]

That is, a "-" before method declaration means instance methods and "+" means class level method which are not related with any particular instance of the class.

Thanks! That is what I was looking for.
