What is the difference between IBOutlet as a property or as a variable?

Question

There are two different methods to declare IBOutlet.

1. In @interface section as variable:

   IBOutlet UIButton *exampleButton;
   

Answer 1

The @property combined with @synthesize setup the getter and setter methods for your objects. You should define it at least in the interface, and if you decide to create a property from it then you must also synthesize it the .m file.
