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) ? – Samhan Salahuddin Dec 27 '12 at 11:51
There are no issues, both ways are correct, the first is just used when you have subclasses – Ismael Dec 27 '12 at 11:52
