I have a rather unexpected result with the following code:
ABAddressBookRef addressBook = ABAddressBookCreate();
CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
NSLog (@"npeople = %d = %d", nPeople, CFArrayGetCount(people));
for (CFIndex i = 0; i < nPeople; i++)
{
ABRecordRef record = CFArrayGetValueAtIndex(people,i);
ABMultiValueRef numbers = ABRecordCopyValue(record, kABPersonPhoneProperty);
CFIndex count = ABMultiValueGetCount(numbers);
NSLog (@"%d %d", i, count);
}
I never reach the second NSLog, it crashes on the call to ABMultiValueGetCount with:
: * -[NSCFString count]: unrecognized selector sent to instance 0x383e72f4
: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '** -[NSCFString count]: unrecognized selector sent to instance 0x383e72f4'
In short, it's behaving as if my "numbers" variable was an NSString. While I wrote the code above myself, the same can be found in many examples on the web. Does someone here spot anything wrong with it?
Oh, and also: it only crashes in Release mode (in debug mode, all is fine).
