ABRecordCopyValue导致SIGSEGV崩溃

3

我正在尝试获取如下联系人列表：

CFErrorRef *error = nil;
ABAddressBookRef addressBook = nil;

__block BOOL accessGranted = NO;

if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined ||
    ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {

    addressBook = ABAddressBookCreateWithOptions(NULL, error);
    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 if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusDenied ||
         ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusRestricted) {
    return nil;
}

if (!accessGranted) {

    if (addressBook) CFRelease(addressBook);
    return nil;
}

CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

if (nPeople <= 0) {
    CFRelease(addressBook);
    return nil;
}

ABRecordRef source = ABAddressBookCopyDefaultSource(addressBook);
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);

if (!allPeople) return nil;

NSMutableArray *contactsArray = [NSMutableArray arrayWithCapacity:nPeople];

for (CFIndex i = 0; i < nPeople; ++i) {

    ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);

    if (!person) continue;

    ContactData *contact = [ContactData new];
    contact.firstName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

在我的 iPhone 5s 和模拟器上运行良好，但构建在测试人员的 iPod 设备上崩溃，并显示 'SIGSEGV' 错误信息：

   contact.firstName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);

以下是堆栈信息：

我有同样的错误，问题是：

CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressBook, source, kABPersonSortByFirstName);

并且

CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

你的应用程序可能给出了不同数量的联系人（因此在你的情况下，nPeople 可能比 allPeople 大，这导致了崩溃）。"source" 似乎没有提供地址簿中的所有联系人。将其更改为 nil 对我有用。另外，为了确保，我会执行：nPeople = CFArrayGetCount(allPeople); Jokinryou Tsui 在这篇文章中非常好地解释了解决方案：ABAddressBookCopyArrayOfAllPeople 和 ABAddressBookGetPersonCount 返回不同的大小（这是我的第一篇帖子，所以我不确定是否违反了任何规则或遵循了正确的程序。我希望这个答案能帮助到你！）
