    <p>Confirmed. <code>bringSubviewToFront:</code> causes <code>layoutSubview</code> to be invoked. Since my version of <code>layoutSubviews</code> sets the z-orders on all the views, this was undoing the z-order I was setting in the <code>touchesBegan:withEvent</code> code above. Apple should mention this side effect in the <code>bringSubviewToFront</code> documentation.</p> <p>Instead of using a <code>UIView</code> subclass, I created a <code>CALayer</code> subclass named <code>CardLayer</code>. I handle the touch in my <code>KlondikeView</code> subclass as listed below. topZPosition is an instance var that tracks the highest zPosition of all cards. Note that modifying the <code>zPosition</code> is usually animated -- I turn this off in the code below:</p> <pre><code>-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event { UITouch *touch = [touches anyObject]; CGPoint touchPoint = [touch locationInView:self]; CGPoint hitTestPoint = [self.layer convertPoint:touchPoint toLayer:self.layer.superlayer]; CALayer *layer = [self.layer hitTest:hitTestPoint]; if (layer == nil) return; if ([layer.name isEqual:@"card"]) { CardLayer *cardLayer = (CardLayer*) layer; Card *card = cardLayer.card; if ([self.solitaire isCardFaceUp:card]) { //... [CATransaction begin]; // disable animation of z change [CATransaction setValue:(id)kCFBooleanTrue forKey:kCATransactionDisableActions]; cardLayer.zPosition = topZPosition++; // bring to highest z // ... if card fan, bring whole fan to top [CATransaction commit]; //... } // ... } } </code></pre>

    1. COI think using `UIView`'s for playing cards may have been a bad design choice -- I don't think they really were intended for this. I think I'll step back and use `CALayer`'s instead.

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).
