Question

A question cropped up while watching a tutorial video.
Are there any rules regarding when to create a pointer in the header file or not?

E.g, let’s say I want to create a new instance of a custom class in my ViewControllers viewDidLoad method.

Without a declaration of the pointer in the header file I won’t be able to access it from outside this specific class?

Answer 1

You declare any properties in your header file. Some objects like custom classes can only be referenced with a pointer there. When you want to use that object on more places then just locally you declare a pointer to that object. This is how you should use pointers in header files.

Just read up on how pointers are used,
