ABUnknownPersonViewController with UIViewController

Question

I want to use ABUnknownPersonViewController with UIViewController .but apple library says that Important: Unknown-person view controllers must be used with a navigation controller in order to function properly.

I am using this with UIViewController it will shows data properly(firstname,lastname) but i is not showing.

my code is

ABUnknownPersonViewController *unknownPersonViewController = [[ABUnknownPersonViewController alloc] init];

unknownPersonViewController.view.frame = CGRectMake(0, 20, 320, 400);
unknownPersonViewController.allowsAddingToAddressBook = YES;
unknownPersonViewController.unknownPersonViewDelegate = self;
unknownPersonViewController.displayedPerson = (ABRecordRef)[addressController buildContactDetails];
[self presentModalViewController:unknownPersonViewController animated:YES];

[unknownPersonViewController release]; 

Answer 1

You should follow Apple's recommendation on using navigation controller. You might make this work properly but there is no knowing when it will break in the future especially since we don't know how these classes are implemented. Consider this part of the API exposed by Apple and stick to it.
