Can't set the addressBook property of ABPeoplePickerNavigationController without crashing

Question

I want to display an ABPeoplePicker with only people who have a geographic address defined.

So I create an addressBook and remove people that dont have an address:

addressBook = ABAddressBookCreate();
NSArray *peopleList = (NSArray *)ABAddressBookCopyArrayOfAllPeople( addressBook );
NSLog(@"There are %d people in addressBook", ABAddressBookGetPersonCount(addressBook));
for (id peopleRecord in peopleList) {
  ABMultiValueRef mv = ABRecordCopyValue((ABRecordRef)peopleRecord, kABPersonAddressProperty);
  CFIndex numberOfAddresses = ABMultiValueGetCount(mv);
  if( numberOfAddresses == 0 ) {
    CFErrorRef err;
    ABAddressBookRemoveRecord( addressBook, (ABRecordRef)peopleRecord, &err);
  }
}
[peopleList release];
NSLog(@"There are now %d people in addressBook", ABAddressBookGetPersonCount(addressBook));
ABPeoplePickerNavigationController *peoplePicker = [[ABPeoplePickerNavigationController alloc] init];
NSNumber* addressProp = [NSNumber numberWithInt:kABPersonAddressProperty];
[peoplePicker setAddressBook:addressBook];
peoplePicker.displayedProperties = [NSArray arrayWithObject:addressProp];
[peoplePicker setPeoplePickerDelegate:self];
[self presentModalViewController:peoplePicker animated:YES];

For info, before filtering I have 125 records, and after filtering I have 93 records.

When I display the peoplePicker and scroll through it, it crashes with:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (49) beyond bounds (49)'

Any idea what's wrong?

Answer 1

The fact that the NSRangeException's value is 49 (rather than some number between 93 and 125), I initially suspect that it's not directly related to this address book. Add a breakpoint for objc_exception_throw. That will cause you to drop into the debugger at the point of the exception, letting you see who's actually throwing it.
