    <p>Have you tried just hard coding the frame logic? This could be very effective. All you have to do is conditionally populate an array containing pointers to your text fields and then perform a little frame arithmetic on their y origins. For example, this could easily display all the fields:</p> <pre><code>NSArray *fields = @[topTextField, middleTextField, bottomTextField]; for (int i = 0 ; i &lt; fields.count ; i ++) { UITextField *field = fields[i]; [field setFrame:CGRectMake(20.0, 20.0 + (i * 50.0), 280.0, 34.0)]; } </code></pre> <p>Produces this:</p> <p><img src="https://i.stack.imgur.com/puy0W.png" alt="enter image description here"></p> <p>Or at its most basic level, something like this could be used to check whether any of the text fields should/shouldn't be shown, and either hides them, or adjusts their frame accordingly.</p> <pre><code>BOOL shouldShowTop = YES; BOOL shouldShowMiddle = NO; BOOL shouldShowBottom = YES; NSMutableArray *fields = [NSMutableArray new]; if (shouldShowTop) { [fields addObject:topTextField]; }else{ [topTextField setHidden:YES]; } if (shouldShowMiddle) { [fields addObject:middleTextField]; }else{ [middleTextField setHidden:YES]; } if (shouldShowBottom) { [fields addObject:bottomTextField]; }else{ [bottomTextField setHidden:YES]; } for (int i = 0 ; i &lt; fields.count ; i ++) { UITextField *field = fields[i]; [field setFrame:CGRectMake(20.0, 20.0 + (i * 50.0), 280.0, 34.0)]; } </code></pre> <p>Will produce this:</p> <p><img src="https://i.stack.imgur.com/93rrX.png" alt="enter image description here"></p>

    1. COI'll look at this in more detail and see how viable it is for my app. If it's really this much coding, I'm tempted to just build two completely separate views (with/without the fields I need) and swap them in/out depending on the condition. But thanks for the food for thought!

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.
