ABPersonViewController error with RubyMotion - rubymotion

Question

I am having trouble using the ABPersonViewController with RubyMotion. The error I'm getting is
Objective-C stub for message setDisplayedPerson:' typev#:^v' not precompiled. Make sure you properly link with the framework or library that defines this message.
I suspect this is due to RubyMotion not casting to the type IOS expects. I think ABPersonCreate() is returning a CFType but the displayedPerson setter is expecting it to be cast as a ABRecordRef (that's just a guess from the error messages)
Here's the sample code to see the problem (based on Apple's QuickContacts sample):
#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
and
# 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}" # => #<__NSCFType:0x8c3bec0>
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
When you run it we are able to add to the address book in the add_person method but it fails in show_person_view_controller on the line picker.displayedPerson = person
$ rake
Build ./build/iPhoneSimulator-5.1-Development
Simulate ./build/iPhoneSimulator-5.1-Development/contacts.app
Should this be an AddressBookRef? #<__NSCFType:0x8da2900>
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.
Any suggestions would be appreciated

This will work properly as of RubyMotion 1.12 (run sudo motion update).
Fixed a bug where performing Objective-C methods that accept
CFType objects
would crash the program (ex. [ABPersonViewController setDisplayedPerson:]).
