Recipe: Tagging and Retrieving Views

The iOS SDK offers a built-in search feature that lets you recover views by tagging them. Tags are just numbers, usually positive integers, that identify a view. Assign them using the view’s tag property: for example, myView.tag = 101. In Interface Builder, you can set a view’s tag in the attributes inspector. As Figure 6-2 shows, you specify the tag in the View section.
