    <p>I am having trouble using the <code>ABPersonViewController</code> with RubyMotion. The error I'm getting is </p> <blockquote> <p>Objective-C stub for message <code>setDisplayedPerson:' type</code>v@:^v' not precompiled. Make sure you properly link with the framework or library that defines this message.</p> </blockquote> <p>I suspect this is due to RubyMotion not casting to the type IOS expects. I think <code>ABPersonCreate()</code> is returning a <code>CFType</code> but the <code>displayedPerson</code> setter is expecting it to be cast as a <code>ABRecordRef</code> (that's just a guess from the error messages)</p> <p>Here's the sample code to see the problem (based on Apple's QuickContacts sample):</p> <pre><code>#Rakefile $:.unshift("/Library/RubyMotion/lib") require 'motion/project' Motion::Project::App.setup do |app| # Use `rake config' to see complete project settings. app.name = 'contacts' app.frameworks += ['AddressBook', 'AddressBookUI'] end </code></pre> <p>and</p> <pre><code># app/app_delegate.rb class AppDelegate def application(application, didFinishLaunchingWithOptions:launchOptions) window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.applicationFrame) window.rootViewController = UINavigationController.alloc.init window.rootViewController.wantsFullScreenLayout = true window.makeKeyAndVisible true # This works add_person('Alex', 'Rothenberg') # This fails (is it a type casting problem?) show_person_view_controller('Rothenberg') end def show_person_view_controller(name) anError = nil address_book = ABAddressBookCreate(); people = ABAddressBookCopyPeopleWithName(address_book, name); person = people.first picker = ABPersonViewController.alloc.init.autorelease picker.personViewDelegate = self puts "Should this be an AddressBookRef? #{person.inspect}" # =&gt; #&lt;__NSCFType:0x8c3bec0&gt; picker.displayedPerson = person # The previous line fails puts "We never reach this line!" self.navigationController.pushViewController(picker, animated:true) end def add_person(first_name, last_name) error = nil contact = ABPersonCreate() ABRecordSetValue( contact, KABPersonFirstNameProperty, first_name, error ) ABRecordSetValue( contact, KABPersonLastNameProperty, last_name, error ) address_book = ABAddressBookCreate() ABAddressBookAddRecord( address_book, contact, error ) ABAddressBookSave( address_book, error ) end end </code></pre> <p>When you run it we are able to add to the address book in the <code>add_person</code> method but it fails in <code>show_person_view_controller</code> on the line <code>picker.displayedPerson = person</code></p> <pre><code>$ rake Build ./build/iPhoneSimulator-5.1-Development Simulate ./build/iPhoneSimulator-5.1-Development/contacts.app Should this be an AddressBookRef? #&lt;__NSCFType:0x8da2900&gt; Objective-C stub for message `setDisplayedPerson:' type `v@:^v' not precompiled. Make sure you properly link with the framework or library that defines this message. </code></pre> <p>Any suggestions would be appreciated</p>

    1. COThis looks like a bug (there were some other CoreFoundation bugs related to the AddressBook framework fixed last week, but it still needs a little work). I filed an official support ticket.

    2. COThanks - I guess I'll wait for an update to RubyMotion then.

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).
