I cant seem to work out how to hide table cells that have no data. In grouped view, you only get a cell per piece of data. Whereas in plain view, it renders the cells to the bottom of the screen. I sure its possible because the world clock does it
Irrespective of the type of table, it’ll fill up the space allocated to it in Interface Builder (or whatever frame is assigned, etc. if you’re creating it programatically).
What you might want to do is set the background as transparent (using the “Clear Color” option as the Background color in the Interface Builder) and use a custom cell background, which is what I believe the world clock does.
To do this, just implement the background in the table cell returned within the tableView:cellForRowAtIndexPath: method by creating a view and using the setBackgroundView and setSelectedBackgroundView methods on the UITableViewCell appropriately.
