私は基本的にUIViewControllerでAFJSONRequestOperationを使用しています。これは、NavigationControllerにプッシュされてJSONをフェッチし、その内容を表示します。クラッシュの原因となっているのはAFNetworkingですか（スレッド5）？それとも私のコードの欠陥でしょうか？私は本当に立ち往生していて、それはかなり頻繁に起こります。ヘルプや質問は大歓迎です！

クラッシュによると、スレッド 5 の問題ではありません。これはスレッド 0 の問題です。

Brian はブログ投稿で、タイマーが webkit でどのように動作するかについての背景情報を追加しています。

http://brrian.tumblr.com/post/13951629341/how-webkits-event-model-works

問題の OS が 6.0.1 であり、新しいバージョンの 6.1 や 7.x (執筆時点) ではないことは興味深いことです。

クラッシュは CFRelease 中に発生し、リソースが既に解放されているときに発生する傾向があります。WebKit のバグのように聞こえるので、新しい OS で問題が発生するかどうかを確認することをお勧めします。Webkit は、タイマーを担当するコードです。

とにかく、タイマーコードは作り直されました: https://trac.webkit.org/changeset/143210

したがって、最新の iOS でこのクラッシュが発生したことがあるか、最新の 6.x (6.1) であるかを確認するのが最善の方法だと思います。

これに失敗し、問題を再現できないと仮定すると、ネットワーク クエリ (および DB クエリ) が実行されているため、タイマーが発生する従来の方法は、低速/信頼性の低いネットワーク接続がある場合です。このような状況をシミュレートするには、Apple のネットワーク リンク コンディショナーを使用します。これにより、WebKit で問題が発生する可能性があります。

一部の広告が iTunes を開いたかどうかを確認します。アプリケーションの初期化で開いているスレッドが多すぎる可能性があります。これらのリクエストをキューに入れることができます。勝手な思い込み..
