Instance Property


The delegate for the picker view.


@property(nonatomic, weak) id<UIPickerViewDelegate> delegate;


The delegate must adopt the UIPickerViewDelegate protocol and implement the required methods to return the drawing rectangle for rows in each component. It also provides the content for each component’s row, either as a string or a view, and it typically responds to new selections or deselections.
