    <p>I get stuck on the following: I want to use a single cell of a UITableView as a header view for another UITableView. The second table view is in turn an object that has been inherited from a different UITableView class, since it shares it's functionality completely. The only difference in fact is that the second UITableView has a header view (which should be the single celled UITableView). </p> <p>The interface for the UITableView with the header looks like:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "ScheduleDetailsController.h" @interface TodayDetailsViewController : ScheduleDetailsController &lt;UITableViewDelegate, UITableViewDataSource&gt; { UITableView *headerView; } @property (nonatomic, retain) UITableView *headerView; @end </code></pre> <p>And the implementation like:</p> <pre><code>#import "TodayDetailsViewController.h" @implementation TodayDetailsViewController @synthesize headerView; - (void)loadView { [super loadView]; self.headerView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; self.headerView.backgroundColor = [UIColor clearColor]; self.headerView.opaque = NO; self.headerView.delegate = self; self.headerView.dataSource = self; // This is a UITableView defined as a property in the parent class self.scheduleDetailsTable.tableHeaderView = self.headerView; } ... #pragma mark - #pragma mark Table View Data Source Methods - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { if (tableView == self.scheduleDetailsTable.tableHeaderView) return 1; else return [self.scheduleDetailsTable numberOfSections]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (tableView == self.scheduleDetailsTable.tableHeaderView) return 1; else return [self.scheduleDetailsTable numberOfRowsInSection:section]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { if (tableView == self.scheduleDetailsTable.tableHeaderView) { ... return cell; } else return [self.scheduleDetailsTable cellForRowAtIndexPath:indexPath]; } @end </code></pre> <p>I get no errors when I compile and run this, but then I also don't see anything, i.e. the view stays empty. I have also tried it with replacing the header view by a UIView and then everything works like expected (i.e. the table view in the parent class is implemented correctly). I'm probably just missing something obvious, but I just can't figure it out at the moment. If someone could spot the error or could give some advice I would be very thankful.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
