How can I tag a property in iOS and track it's state throughout the app?

Is there a way to tag a property or Instance variable throughout the life
of the application and see it changes?
The idea would be to see how the property is changed and what class/object
changes it's value when that value is passed around a lot? This way we
could see its value every time it changes instead of filling the code with
breakpoints.
