ユーザーがアドレス帳にアクセスしたときのクラッシュレポート

Question

私のアプリケーションでは、Crashlyticsはユーザーからクラッシュレポートを収集するために使用されます。ユーザーからのクラッシュレポートが1つあります。おそらくユーザーの連絡先情報に依存しています。私は彼/彼女の連絡先に何があるかわからないので、クラッシュを再現することはできません。どのような人がこの状況について考えていますか？

Answer 1

それはあなたがABAddressBookCreateWithOptionsを呼んでいることだろう（）、および/またはABAddressBookRequestAccessWithCompletion（）あなたがABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering（）を呼び出している場所とは別のスレッドで？

AppleのAPIドキュメントから、次の点に注意してください。

完了ハンドラを任意のキューに呼ばれています。アプリ全体でアドレス帳を使用している場合は、スレッドセーフな操作が確実に行われるように、そのアドレス帳のすべての使用が単一のキューに確実に送信されるようにする必要があります。

出典：

はまた、あなたが途中であなたがABAddressBookCreateWithOptionsから戻ったABAddressBookRefを（）を放出していないことを確認するチェックしhttp://developer.apple.com/library/ios/#documentation/AddressBook/Reference/ABAddressBookRef_iPhoneOS/Reference/reference.html。 ABAddressBookRequestAccessWithCompletion（）は非同期であることに注意してください。

Answer 2

私は

ABAddressBookはスレッドセーフではありませんので、あなたは、2つの異なるスレッド、 からそれを呼び出す場合に例外をスローすると、アプリがクラッシュクラッシュしたスレッドは「com.apple.root.default-優先」であることがわかり。

DISPATCH_QUEUE_PRIORITY_DEFAULTはシリアルキューではないため、常にDISPATCH_QUEUE_PRIORITY_DEFAULTへのコールをディスパッチしても、2つの異なるスレッドで実行される可能性があります。このキューにアドレス帳に

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)); 

を派遣することを忘れないでください（同期または非同期）すべてのコール：

使用これはDISPATCH_QUEUE_PRIORITY_DEFAULTする派遣シリアルキューを作成します。

EDIT：

あなたが機能ABAddressBookRequestAccessWithCompletionに渡さ完了ハンドラブロックにdofetchContactsを呼び出しているように見えます。この呼び出しをメインスレッドにディスパッチしてください！

ドキュメントは言う：

完了ハンドラを任意のキューに呼ばれています。アプリ全体で がアドレス帳を使用している場合は、 を使用して、そのアドレス帳のすべての使用が確実に正しいキューにディスパッチされ、スレッドセーフな操作が確実に行われるようにしてください。
