Answer 1

Okay, what I'm thinking is, The titles, Events, Overhead and Friends would be the custom UIView with UIImageView for background, UILabel for title, and UIButton for expand. So basically

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

having return count of the titles you've.

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

having return UIView for each titles.

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

having count of the rows within that title. You may need to maintain an array for this.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;

having height of the cell item

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section

initially it should be 0 (zero) for all sections, when user tap on expand, it should be increase with respect to number of rows * cell height within that section.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

You may need some good logic for setting all rows for expansion

Your expansion buttons actions something like,

- (void) expandSection:(UIButton *)sender;

that you can identify which section to be expand using sender.tag, so don't forget to add tag properly. You may need an int in .h file for store the current section, and can be use in - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section datasource method.
