    <p>Have you considered using 4 separate cell identifiers for the "lonely, "top", "bottom", and "middle" cases and setting the <code>backgroundView</code> only once when initializing the cell? Doing it that way lets you leverage <code>UITableView</code>'s own caching and reuse without having to write an implementation on top of it.</p> <hr> <p><strong>Update</strong>: An implementation for a grouped <code>UITableViewController</code> subclass that reuses background views with a minimal number of cell reuse identifiers (Espresso's use case). <code>tableView:willDisplayCell:forRowAtIndexPath:</code> and <code>tableView:didDisplayCell:forRowAtIndexPath:</code> do the heavy lifting to apply or reclaim each background view, and the pooling logic is handled in <code>backgroundViewForStyle:</code>.</p> <pre><code>typedef NS_ENUM(NSInteger, JSCellBackgroundStyle) { JSCellBackgroundStyleTop = 0, JSCellBackgroundStyleMiddle, JSCellBackgroundStyleBottom, JSCellBackgroundStyleSolitary }; @implementation JSMasterViewController { NSArray *backgroundViewPool; } - (void)viewDidLoad { [super viewDidLoad]; // these mutable arrays will be indexed by JSCellBackgroundStyle values backgroundViewPool = @[[NSMutableArray array], // for JSCellBackgroundStyleTop [NSMutableArray array], // for JSCellBackgroundStyleMiddle [NSMutableArray array], // for JSCellBackgroundStyleBottom [NSMutableArray array]];

    1. COI have looked into doing this, but I don't wanna have to do this because it's gonna get hairy once reusable custom cells (e.g., text field cell, switch cell, slider cell) are taken into account.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
