copied!<p>I found that you can simply put that View into the bucket in Xcode, but not in the view controller. (See pic)</p> <p><img src="https://i.stack.imgur.com/1Wav2.png" alt="Not in the view controller"></p> <p>Then, I found that if I made an outlet to that <code>UIView</code>, I could still use it. Note that I had to design the view and make it the proper size, etc either programatically, or in IB before I moved it to this position, since I cannot see it anymore in IB. </p> <p>Then, in the <code>TableViewController</code> class, I used <code>ViewWillAppear</code> to check the count of the array that backs up the TableView. If it was zero, I set the view (using the Outlet) to be hidden or not. </p> <p>Next, I used this code:</p> <pre><code>-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { if (noConnectionView.hidden) { return 0; } else { return 480; } } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if (noConnectionView.hidden) { return nil; } else { return noConnectionView; } } </code></pre> <p>This makes it fill my popover, and since the number of cells for section method returns the same count that I already checked (which is zero, if the table is empty) that is the only thing displayed (no empty cells). </p> <p>When there are things to display, <code>ViewWillAppear</code> is called each time (and whenever things are deleted, I call view will appear again) and then the tableView gets rid of the header and it behaves like a normal tableView. </p> <p>This is great because you can use it with a <code>UITableViewController</code> or in sequence with a navigation controller. </p>
