This is the on-screen representation of a generic picker.
全てのデバイスで同じような一般レイアウトを持つが、印象はデバイス固有である印象を与える。 ピッカーは一つもしくはそれ以上の選択するオブジェクト、タイトル、次・前を表す矢印、そして確認ボタンで構成される。次・前矢印と確認ボタンはデバイス固有だが、もし必要なら上書きできる。ピッカーは WatchUi.pushView() でプッシュされ、PickerDelegate 。各選択値に何を表示するかために、PickerFactory が必要になる
A Picker uses a PickerFactory to decide what to display to the user. It is capable of displaying any number of entries for the user to choose from. For instance, if the PickerFactory was [new NumberFactory(), new Ui.Text(:text=>“-”), new NumberFactory()] then the Picker will have three entries: a choosable number, a non-choosable “-”, and another choosable number.
