you can do like:

- (void)your_instanceMethodB
{

    [[self class] your_classMethodA];

}

If you are using subclasses and your subclass overrides the method, then you should do

 [[self class] myFunction];

If not, the standard way is correct

[MyClass myFunction];

Which one is the best practice ? Are there any other issues i need to be aware of (other than inheritance) ?

There are no issues, both ways are correct, the first is just used when you have subclasses
