you will use strong most of the time. You use weak when your property is part of a parent-child relationship (such as textFields on a viewController. The controller has a strong reference to the textFields (children), however the textFields have a weak reference to the controller (parent) ). you also can only use strong for object properties. If you have a property of a primitive type you could use assign, or copy, but not strong since primitives are not objects. This post provides a detailed explanation of ARC and strong vs weak properties.
