How to specify a group when displaying an ABPeople

问题:

How do you specify a group when initially displaying an ABPeoplePickerNavigationController (so it doesn't automatically display "All Contacts")?

回答1:

Yeah, I do. I had to make it work.

Set your class as the delegate of the people picker (pp.delegate = self;)

Then implement:

- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if([navigationController.viewControllers count] > 1) {
        navigationController.delegate = nil;
        [navigationController popViewControllerAnimated:NO];
    }
}

It seems to work best with animation off, but still works with it on but sort of goofy. Only tested on simulator.
