在我的应用中，Crashlytics用于收集用户的崩溃报告。这是来自用户的一个崩溃报告。它可能取决于用户的联系信息。我无法重建崩溃，因为我不知道他/她的联系人是什么。有没有人对这种情况有所了解？

我看到崩溃的帖子是“com.apple.root.default-priority”
ABAddressBook不是线程安全的，所以如果你从两个不同的线程调用它， 它抛出异常并使应用程序崩溃。
即使您始终将调用分派给DISPATCH_QUEUE_PRIORITY_DEFAULT，它也可能在两个不同的线程上运行，因为DISPATCH_QUEUE_PRIORITY_DEFAULT不是串行队列。
使用此命令创建分派到DISPATCH_QUEUE_PRIORITY_DEFAULT的串行队列：
dispatch_queue_t abQueue = dispatch_queue_create("myabqueue", DISPATCH_QUEUE_SERIAL);
dispatch_set_target_queue(abQueue, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0));
请记住将您对地址簿的所有呼叫分派（同步或异步）到此队列。
修改
看起来你在传递给函数ABAddressBookRequestAccessWithCompletion的完成处理程序块中调用了dofetchContacts。务必在主线程上发出此调用！
文档说：
在任意队列上调用完成处理程序。如果你的应用程序 在整个应用程序中使用通讯录，您负责 确保将该地址簿的所有使用情况分发给一个人 排队以确保正确的线程安全操作。
答案 1 :(得分：5)
你是否在调用ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering（）的不同线程上调用ABAddressBookCreateWithOptions（）和/或ABAddressBookRequestAccessWithCompletion（）？
请注意Apple的API文档中的以下内容：
在任意队列上调用完成处理程序。如果您的应用在整个应用中使用地址簿，则您有责任确保将该地址簿的所有使用情况分发到单个队列，以确保正确的线程安全操作。
或者，检查以确保您没有过早地释放从ABAddressBookCreateWithOptions（）返回的ABAddressBookRef。请记住，ABAddressBookRequestAccessWithCompletion（）是异步的。
