Question

I see that the UIColor class can call the variable like this [UIColor redColor];
How can I write my class to do the same thing? Also, can I have a method only for class, for example, like this:

[MyClass callingMyMethod];

Thank you.

Answer 1

Yes. Just use a + instead of a - when declaring the method:

+ (void)callingMyMethod
{
   ...
}
