How to add a label in a settings screen

Question

As a picture says more than a thousand words: alt text http://img.skitch.com/20091008-k16k7we3t43gj3h7htgtjpunpx.jpg

Any help on how to add descriptive labels to a settings pane would be highly appreciated! I should point out that I want to do this to be in the iPhone-App settings that are in the Settings menu of the iPhone (outside the App).

Example label:

• iPhone -> Settings -> Safari -> Fraud Warning
• The label beneath: "Warn when visiting fraudulent websites."

Answer 1

Unfortunately, Apple has not given iPhone developers the capability to add the kind of label you're looking for in Settings.app. As a near approximation, I've used PSGroupSpecifier under another setting element (such as PSToggleSwitchSpecifier). It's not as elegant as a true label, but it worked well enough in my situation (I only had one setting, so it didn't conflict with any other group headings).

Answer 2

For reference: Since iOS4.0 and above a FooterText key was added to PSGroupSpecifier that does exactly what you are looking for.

Answer 3

Try using a PSTitleValueSpecifier in your settings bundle's plist. I'm not sure how that formats itself—most likely bold, like the group headers—but it might be what you're looking for.

Answer 4

If you want to simulate a label that is center-justified, add an empty title PSGroupSpecifier and put your label text in the FooterText Key.

Answer 5

Check out the tableView:titleForFooterInSection: method of UITableViewDataSource. You can return a string to be displayed below a table view section. If you're already using a UITableViewController subclass, just implement that method and you're good to go.
