The UIPickerView class implements objects, called picker views, that use a spinning-wheel or slot-machine metaphor to show one or more sets of values. Users select values by rotating the wheels so that the desired row of values aligns with a selection indicator.
The UIDatePicker class uses a custom subclass of UIPickerView to display dates and times. To see an example, tap the add ("+") button in the the Alarm pane of the Clock application.
The user interface provided by a picker view consists of components and rows. A component is a wheel, which has a series of items (rows) at indexed locations on the wheel. Each component also has an indexed location (left to right) in a picker view. Each row on a component has content, which is either a string or a view object such as a label (UILabel) or an image (UIImageView).
