# UIExpandableTableView UIExpandableTableView is a UITableView subclass that gives you easy access to expandable and collapsable sections by just implementing a few more delegate and dataSource protocols. ## How to use UIExpandableTableView * Load the UIExpandableTableView in a UITableViewController ```objective-c - (void)loadView { self.tableView = [[UIExpandableTableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain]; } ``` * Implement the **UIExpandableTableViewDatasource** protocol ```objective-c - (BOOL)tableView:(UIExpandableTableView *)tableView canExpandSection:(NSInteger)section { // return YES, if the section should be expandable } - (BOOL)tableView:(UIExpandableTableView *)tableView needsToDownloadDataForExpandableSection:(NSInteger)section { // return YES, if you need to download data to expand this section. tableView will call tableView:downloadDataForExpandableSection: for this section } - (UITableViewCell<UIExpandingTableViewCell> *)tableView:(UIExpandableTableView *)tableView expandingCellForSection:(NSInteger)section { // this cell will be displayed at IndexPath with section: section and row 0 } ``` * Implement the **UIExpandableTableViewDelegate** protocol ```objective-c - (void)tableView:(UIExpandableTableView *)tableView downloadDataForExpandableSection:(NSInteger)section { // download your data here // call [tableView expandSection:section animated:YES]; if download was successful // call [tableView cancelDownloadInSection:section]; if your download was NOT successful } ``` ## Sample Screenshots <img src="https://github.com/OliverLetterer/UIExpandableTableView/raw/master/Screenshots/1.png"> <img src="https://github.com/OliverLetterer/UIExpandableTableView/raw/master/Screenshots/2.png">
