As you begin to program iOS applications, you need to first understand the concept of outlets and actions. In iOS programming, you use actions and outlets to connect your code to the various views in your UI. Think of actions as event handlers in the traditional object-oriented programming world, and outlets as object references. If you are familiar with traditional programming languages such as Java or C#, this is a concept that requires some time to get used to — not because it is difficult, but because it is a different way of doing things.
