how to check for non used variables in Xcode 4

Question

I am wondering if there is an option in xcode that will let you debug a variable to see if it's being used in your code anywhere?

I find sometimes I make changes to my code, then I look at all of my synthesised variables and I'm just not positive that they are being used.. I don't mind going through my code and checking but I thought it would be more productive if their was a function that would help me do this quicker?

Dose anyone know of such a thing?

You can set the Unused parameter warnings in the Build Settings of your project. Just search "Unused" when looking for the option.
