在我的应用程序中，Crashlytics 用于收集用户的崩溃报告。这是一位用户的崩溃报告。这可能取决于用户的联系人信息。我无法重现崩溃，因为我不知道他/她的联系人中有什么。有人知道这种情况吗？

最佳答案

我看到崩溃的线程是“com.apple.root.default-priority”

ABAddressBook 不是线程安全的，因此如果您从两个不同的线程调用它， 它抛出异常并使应用程序崩溃。

即使您总是将调用分派(dispatch)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。

使用它来创建您的串行队列，该队列分派(dispatch)到 DISPATCH_QUEUE_PRIORITY_DEFAULT:

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));

请记住将所有对地址簿的调用分派(dispatch)(同步或异步)到此队列。

编辑:

您似乎在传递给函数 ABAddressBookRequestAccessWithCompletion 的完成处理程序 block 中调用 dofetchContacts。请务必在主线程上分派(dispatch)此调用!

文档说:

The completion handler is called on an arbitrary queue. If your app uses an address book throughout the app, you are responsible for ensuring that all usage of that address book is dispatched to a single queue to ensure correct thread-safe operation.
