SCSelectionSection

@interface SCSelectionSection : SCArrayOfStringsSection {
  BOOL boundToNSNumber;
  BOOL boundToNSString;
  NSIndexPath *lastSelectedRowIndexPath;
  BOOL allowMultipleSelection;
  BOOL allowNoSelection;
  NSUInteger maximumSelections;
  BOOL autoDismissViewController;
  NSMutableSet *_selectedItemsIndexes;
}

This class functions as an SCTableViewModel section that is able to provide selection functionality. The cells in this section represent different items that the end-user can select from, and they are generated from NSStrings in its items array. Once a cell is selected, a checkmark appears next to it, similar to Apple’s Settings application where a user selects a Ringtone for their iPhone. The section can be configured to allow multiple selection and to allow no selection at all.

There are three ways to set/retrieve the section’s selection:

  • Through binding an object to the section, and specifying a property name to bind the selection index result to. The bound property must be of type NSMutableSet if multiple selection is allowed, otherwise it must be of type NSNumber or NSString.
  • Through binding a key to the section and setting/retrieving through the ownerTableViewModel modelKeyValues property.

  • Through the selectedItemsIndexes or selectedItemIndex properties.

Creation and Initialization

  • Allocates and returns an initialized ‘SCSelectionSection’ given a header title, a bound object, an NSNumber bound property name, and an array of selection items.

    Declaration

    Objective-C

    + (instancetype)sectionWithHeaderTitle:(NSString *)sectionHeaderTitle
                           boundObject:(NSObject *)object
             selectedIndexPropertyName:(NSString *)propertyName
                                 items:(NSArray *)sectionItems;

    Parameters

    sectionHeaderTitle

    A header title for the section.
    object

    The object the section will bind to.
    propertyName

    The property name present in the bound object that the section will bind to and will automatically change the value of to reflect the section’s current selection. This property must be of type NSNumber and can’t be a readonly property. The section will also initialize its selection from the value present in this property.
    sectionItems

    An array of the items that the user will choose from. All items must be of an NSString type.

    Note

    In case of no selection, this property will be set to an NSNumber of value -1.

    Declaration
