    <p>While I agree that tag will work in many circumstances, it's a pain to work with integer tags when you have a matrix of 100 buttons that are pushable where you want to identify: (1) what was pushed and (2) what value was pushed. I found myself starting to invent row/column naming schemes with tag numbers which got out of hand.</p> <p>I wanted multiple controls to share the same handler, and I wanted to carefully design my UI in IB to pass name/value pairs off to a key-value store based on what was pushed.</p> <p>As an alternative to tags, I came up with another workaround for UISegmentedControl (it works for other controls too).</p> <p>(1) Create a new class and sub-class UISegmentedControl. Add a string property MyCustomKey to your new class.</p> <pre><code>@interface CustomSegmentedControl : UISegmentedControl @property (nonatomic, retain) NSString* myCustomKey; @end </code></pre> <p>(2) Back in IB, modify your UISegmentedContol instances to be instances of CustomSegmentedControl. Used the IB "User Defined Runtime Attributes" to set the value of myCustomKey using IB. KeyValueCoding will take care of the setting of the properties for you:</p> <p><img src="https://i.stack.imgur.com/TOmg3.png" alt="screen shot of setting your custom property through interface building"></p> <p>(3) Wire up all your buttons to a single IBAction.</p> <p>(4) In your IBAction, you can extract the key-value pairs now by reading back your custom attribute:</p> <pre><code>- (IBAction)myButtonPressed:(id) sender { if ([sender isKindOfClass:[CustomSegmentedControl class]] == false) return; // get the key-values from the control CustomSegmentedControl *control = (CustomSegmentedControl *)sender; NSString *key = [control valueForKey:@"myCustomKey"]; NSNumber *value = [NSNumber numberWithInteger:[control selectedSegmentIndex]]; NSLog(@"Pressed control %@ with a value of %@", key, value); } </code></pre> <p>In this case I was only interested in the integer value of a segmented control, but you could get any property off the control as the value.</p> <p>Hope this helps.</p>

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.
