}
[people release];

Answer 1

You are doing an unnecessary release here, CFRelease(person);. You are just getting the value directly from an array so you shouldn't release it. Moreover, the ABPersonViewController object doesn't retain the person object assigned to displayedPerson so this results in an error when it tries to access the object which has been released.

Answer 2

If you want the personview to open in edit mode, in addition to allowsEditing = YES, you need to specify setEditing:YES:
[personController setEditing:YES animated:NO];

Answer 3

Use this line instead of that in your code,
ABPersonViewController *personController = [[ABPersonViewController alloc] initWithNibName:#"ABPersonViewController" bundle:nil];
