Method Detail

numberOfSectionsInTableView

default long numberOfSectionsInTableView(UITableView tableView)

Default is 1 if not implemented

sectionIndexTitlesForTableView

default NSArray<java.lang.String> sectionIndexTitlesForTableView(UITableView tableView)

return list of section titles to display in section index view (e.g. "ABCD...Z#")

tableViewCanEditRowAtIndexPath

default boolean tableViewCanEditRowAtIndexPath(UITableView tableView,
                                               NSIndexPath indexPath)

Individual rows can opt out of having the -editing property set for them. If not implemented, all rows are assumed to be editable.

tableViewCanMoveRowAtIndexPath

default boolean tableViewCanMoveRowAtIndexPath(UITableView tableView,
                                               NSIndexPath indexPath)

Allows the reorder accessory view to optionally be shown for a particular row. By default, the reorder control will be shown only if the datasource implements -tableView:moveRowAtIndexPath:toIndexPath:

tableViewCellForRowAtIndexPath

UITableViewCell tableViewCellForRowAtIndexPath(UITableView tableView,
                                               NSIndexPath indexPath)

Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier: Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)

tableViewCommitEditingStyleForRowAtIndexPath

default void tableViewCommitEditingStyleForRowAtIndexPath(UITableView tableView,
                                                          long editingStyle,
                                                          NSIndexPath indexPath)

After a row has the minus or plus button invoked (based on the UITableViewCellEditingStyle for the cell), the dataSource must commit the change Not called for edit actions using UITableViewRowAction - the action's handler will be invoked instead

tableViewMoveRowAtIndexPathToIndexPath

default void tableViewMoveRowAtIndexPathToIndexPath(UITableView tableView,
                                                    NSIndexPath sourceIndexPath,
                                                    NSIndexPath destinationIndexPath)

Data manipulation - reorder / moving support

tableViewNumberOfRowsInSection

long tableViewNumberOfRowsInSection(UITableView tableView,
                                    long section)

tableViewSectionForSectionIndexTitleAtIndex

default long tableViewSectionForSectionIndexTitleAtIndex(UITableView tableView,
                                                         java.lang.String title,
                                                         long index)

tell table which section corresponds to section title/index (e.g. "B",1))

tableViewTitleForFooterInSection

default java.lang.String tableViewTitleForFooterInSection(UITableView tableView,
                                                          long section)

tableViewTitleForHeaderInSection

default java.lang.String tableViewTitleForHeaderInSection(UITableView tableView,
                                                          long section)

fixed font style. use custom view (UILabel) if you want something different
