dealloc, use release or set to nil for properties?

Question

I have noticed a little confusion when looking at various bits of code both in books and on the web when it comes to implementing dealloc. My question is when using @propert

There is no real difference, Unless you are not using the @synthesize keyword. When you set the properties to nil, they are being released behind the scenes by the setter. Now, there may be a slight performance increase over the fist version, because not so much needs to happen behind the scenes (e.g. pointer comparison, and everything else apple hides behind the scenes). I always use version 001, because it is more to the point and future developers don't have to dig though my code to figure out what I am accomplishing.
