@protocol SCSCategoryViewControllerDelegate <NSObject>

Delegate protocol to allow the receiver to interact with, and control the experience of, a category view controller.

  • Informs the delegate when a category is assigned and it begins to load.

    Declaration

    Objective-C

    - (void)categoryController:(nonnull SCSCategoryViewController *)controller
          willLoadCategory:(nonnull SCSCategory *)category;

    Swift

    optional func categoryController(_ controller: SCSCategoryViewController, willLoad category: SCSCategory)

    Parameters

    controller

    The SCSCategoryViewController instance.
    category

    The category that was assigned to the controller.

  • Informs the delegate when a category is assigned and it completes loading.

    Declaration

    Objective-C

    - (void)categoryController:(nonnull SCSCategoryViewController *)controller
           didLoadCategory:(nonnull SCSCategory *)category;

    Swift

    optional func categoryController(_ controller: SCSCategoryViewController, didLoad category: SCSCategory)

    Parameters

    controller

    The SCSCategoryViewController instance.
    category

    The category that was assigned to the controller.

  • Informs the delegate when a category is selected.

    Declaration

    Objective-C

    - (BOOL)categoryController:(nonnull SCSCategoryViewController *)controller
     childCategorySelected:(nonnull SCSCategory *)category;

    Swift

    optional func categoryController(_ controller: SCSCategoryViewController, childCategorySelected category: SCSCategory) -> Bool

    Parameters

    controller

    The SCSCategoryViewController instance.
    category

    The category that was selected.

    Return Value

    YES if the built-in default action should be performed, otherwise NO if no action should be performed.

  • Informs the delegate when an article is selected.

    Declaration

    Objective-C

    - (BOOL)categoryController:(nonnull SCSCategoryViewController *)controller
           articleSelected:(nonnull SCSArticle *)article;

    Swift

    optional func categoryController(_ controller: SCSCategoryViewController, articleSelected article: SCSArticle) -> Bool

    Parameters

    controller

    The SCSCategoryViewController instance.
    article

    The article that was selected.

    Return Value

    YES if the built-in default action should be performed, otherwise NO if no action should be performed.

  • Informs the delegate when the Show More Articles row is tapped.

    This is only supported on controllers that have child categories, and whose display mode is SCSCategoryDisplayModeArticlesAndCategories.

    Declaration

    Objective-C

    - (BOOL)categoryController:(nonnull SCSCategoryViewController *)controller
    showMoreArticlesSelectedForCategory:(nonnull SCSCategory *)category;

    Swift

    optional func categoryController(_ controller: SCSCategoryViewController, showMoreArticlesSelectedFor category: SCSCategory) -> Bool

    Parameters

    controller

    The SCSCategoryViewController instance.
    category

    Return Value

    YES if the built-in default action should be performed, otherwise NO if no action should be performed.

  • Allows the delegate to customize the header view used for the indicated type.

    If nil is returned, then no header will be used for that section.

    If you want to use the default header view, don’t implement this method.

    The SCSCategoryHeaderTypeChildCategories header type is only requested of the delegate when the selected category has child categories, and when the display mode is SCSCategoryDisplayModeArticlesAndCategories.

    Declaration

    Objective-C

    - (nullable __kindof UIView *)
    categoryController:(nonnull SCSCategoryViewController *)controller
     headerViewForType:(SCSCategoryHeaderType)headerType
           forCategory:(nonnull SCSCategory *)category;

    Swift

    optional func categoryController(_ controller: SCSCategoryViewController, headerViewFor headerType: SCSCategoryHeaderType, for category: SCSCategory) -> UIView?

    headerType

    The type of header view being requested.
    category

    The category being shown.

    Return Value
