    Modal views focus the user on the task at hand...

    When users navigate through your app, they are used to seeing views pushed and popped as they move through the data. However, some tasks are different than the normal drill-down navigation and we really need to call the user’s attention to what’s going on. iOS does this through modal views. These are normal views from your (the developer’s) perspective, but feel different to the user in a few ways:

    ...like adding or editing items

    We’re going to use a modal view when users want to add a new drink to DrinkMixer. They have to either save the added drink or discard (cancel) it before they can return to the main DrinkMixer app. So we want a view that encourages the user to make that choice.
