In my iPad app (Xcode 5, iOS 7, ARC, Storyboards), I'm trying to read the Address book and get all of the entries. Unfortunately, I get the following error:
SalonBook[2225:a0b] -[__NSCFString count]: unrecognized selector sent to instance 0xb335e70
This is my code that I copied from SO (why re-invent the wheel?).
-(IBAction)importClientData:(UIButton *)sender {
NSMutableArray *allContacts = [[NSMutableArray alloc] init];
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
for(int i = 0;i<ABAddressBookGetPersonCount(addressBook);i++)
{
NSMutableDictionary *aPersonDict = [[NSMutableDictionary alloc] init];
ABRecordRef ref = CFArrayGetValueAtIndex(people, i);
NSString *fullName = (__bridge NSString *) ABRecordCopyCompositeName(ref);
if (fullName) {
[aPersonDict setObject:fullName forKey:@"fullName"];
// collect phone numbers
NSMutableArray *phoneNumbers = [[NSMutableArray alloc] init];
ABMultiValueRef phones = ABRecordCopyValue(ref, kABPersonPhoneProperty);
for(CFIndex j = 0; j < ABMultiValueGetCount(phones); j++) {
NSString *phoneNumber = (__bridge NSString *) ABMultiValueCopyValueAtIndex(phones, j);
[phoneNumbers addObject:phoneNumber];
}
[aPersonDict setObject:phoneNumbers forKey:@"phoneNumbers"];
// collect emails - key "emails" will contain an array of email addresses
ABMultiValueRef emails = ABRecordCopyValue(ref, kABPersonEmailProperty);
NSMutableArray *emailAddresses = [[NSMutableArray alloc] init];
for(CFIndex idx = 0; idx < ABMultiValueGetCount(emails); idx++) {
NSString *email = (__bridge NSString *)ABMultiValueCopyValueAtIndex(emails, idx);
[emailAddresses addObject:email];
}
[aPersonDict setObject:emailAddresses forKey:@"emails"];
// if you want to collect any other info that's stored in the address book, it follows the same pattern.
// you just need the right kABPerson.... property.
[allContacts addObject:aPersonDict];
}
else {
// Note: I have a few entries in my phone that don't have a name set
// Example one could have just an email address in their address book.
}
}
}

No matter what code I use (I have tried several variations of the above code) they all crash on the same call (-ABAddressBookCreateWithOptions). Since I copied the same code from multiple examples, I would expect at least this line to work. It's not! Why?
It is not clear whether or not you are calling ABAddressBookRequestWithCompletion to obtain the user's permission to access the address book. If you don't do this on an app targeting iOS 6 or newer, you will not be allowed to access the address book. That being said, AddressBook API should not crash in this way. You may need to report a bug to apple via bugreport.apple.com.
