using self vs. _

When is it right to use which? I understand that the underscore skips the getter and setter and goes straight with the property whereas self accesses the getter and setter. So you wouldn't use self in the setter method since that would cause an infinite loop. So can you always just use the underscore?

Theoretically you could always reference the iVar of the property with the _iVarName but IMHO that would be really bad practice - I'd like to recommend always going the self.propertyName way (with the exception of the situation where you are going to make your own setter/getter, of course - as you already wrote...and some other extremely seldom occuring situations).
