Right way to use ABPersonViewController?

I'm pretty new to Objective-C, so I'm sorry in advance if I'm missing something you would consider obvious :)

I wrote a simple program to display the Address Book, and select a user(mimicking the iOS Contact list).

I have a basic controller:

@interface BasicViewController : 
UIViewController<ABPersonViewControllerDelegate>

The controller recieves an ABRecordRef from a previous view. In one of my methods, I use:

ABPersonViewController* ctrl = [[ABPersonViewController alloc]init];

ctrl.allowsEditing = NO;
[ctrl setPersonViewDelegate:self];
[ctrl setDisplaydPerson:person];

[self setView:ctrl.view];
[self.navigationController pushViewController:ctrl animated:
YES];

When I get to the actual view, I get a blank screen(with the background associated with an ABPersonView). I fiddled a bit with displayedProperties:

ctrl.displayedProperties = [NSArray arraywithObjects:
     [NSNumber numberWithInt:kABPersonLastNameProperty],nil];

When I specified that I only wanted to see the last name - a message appeared on the same view - NO_VALUE_UNKNOWN

I checked in debug, and my ABRecordRef isn't null, and contains all of the relevant strings.

Any ideas?

Solution

  • Solved it :) I called a method containing the code displayed above from a segue. the viewDidLoad method of the super wasn't called until after my method was.

    when I rearranged the calling order, it worked like a charm :)
