Question

当我在我的iphone联系人中同步facebook联系人时，我的应用程序崩溃了所有电话联系人。应用程序每次在名字上崩溃都会导致访问不良。如果Facebook朋友没有同步，应用程序工作正常。这是我的代码：

+(NSMutableArray *)getAllContacts
{
    CFErrorRef *error = nil;

    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);

    __block BOOL accessGranted = NO;
    if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
        dispatch_semaphore_t sema = dispatch_semaphore_create(0);
        ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
            accessGranted = granted;
            dispatch_semaphore_signal(sema);
        });
        dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);

    }
    else { // we're on iOS 5 or older
        accessGranted = YES;
    }

    if (accessGranted)
    {

#ifdef DEBUG
        NSLog(@"Fetching contact info ----> ");
#endif
        ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
        ABRecordRef source = ABAddressBookCopyDefaultSource(addressBook);
        CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);
        CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
        NSMutableArray* items = [NSMutableArray arrayWithCapacity:nPeople];

        for (int i = 0; i < nPeople; i++)
        {
            NSMutableDictionary *contacts = [NSMutableDictionary new];
            ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);

            //get First Name and Last Name

            NSString *firstName = (__bridge NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

            NSString *lastName =  (__bridge NSString*)ABRecordCopyValue(person, kABPersonLastNameProperty);

            NSString *name=@"";

            if ([firstName length]>0 && [lastName length]>0)
                name= [NSString stringWithFormat:@"%@ %@",firstName,lastName];
            else if ([firstName length]>0 && [lastName length]==0)
                name= [NSString stringWithFormat:@"%@",firstName];
            else if ([firstName length]==0 && [lastName length]>0)
                name= [NSString stringWithFormat:@"%@",lastName];
            else
                name= @"No Name";

            contacts[@"name"]=name;

            // get contacts picture, if pic doesn't exists, show standart one

            NSData  *imgData = (__bridge NSData *)ABPersonCopyImageData(person);
            UIImage *image= [UIImage imageWithData:imgData];
            if (!image)
                image = [UIImage imageNamed:@"profilebase_small.png"];
            contacts[@"image"]=image;
            //get Phone Numbers

            NSMutableArray *phoneNumbers = [[NSMutableArray alloc] init];

            ABMultiValueRef multiPhones = ABRecordCopyValue(person, kABPersonPhoneProperty);
            for(CFIndex i=0;i<ABMultiValueGetCount(multiPhones);i++) {

                CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(multiPhones, i);
                NSString *phoneNumber = (__bridge NSString *) phoneNumberRef;
                [phoneNumbers addObject:phoneNumber];
            }

            contacts[@"numbers"]=phoneNumbers;
            //get Contact email

            NSMutableArray *contactEmails = [NSMutableArray new];
            ABMultiValueRef multiEmails = ABRecordCopyValue(person, kABPersonEmailProperty);

            for (CFIndex i=0; i<ABMultiValueGetCount(multiEmails); i++) {
                CFStringRef contactEmailRef = ABMultiValueCopyValueAtIndex(multiEmails, i);
                NSString *contactEmail = (__bridge NSString *)contactEmailRef;

                [contactEmails addObject:contactEmail];
                // NSLog(@"All emails are:%@", contactEmails);

            }

            contacts[@"emails"]=contactEmails;



            [items addObject:contacts];
        }
        return items;
    } else
    {
#ifdef DEBUG
        NSLog(@"Cannot fetch Contacts :( ");
#endif
        return NO;
    }
}

替换此行CFIndex nPeople = ABAddressBookGetPersonCount（addressBook）;与CFIndex nPeople = CFArrayGetCount（allPeople）;

当手机联系与ios中的facebook朋友联系同步时，应用程序崩溃
