UIWebViewベースのブラウザを iPad アプリケーションに含めようとしています。デバッグに時間がかかるため、デバッグが難しくなりますが、最終的にアプリは常に同じ場所 (JavaScriptCoreWTF::StringImpl::hash()関数の WebThread) でクラッシュします。生成しEXC_BAD_ACCESS (SIGSEGV), KERN_INVALID_ADDRESS at 0x00000001ます。
はUIWebView、スタックのような方法で別のビュー コントローラー (コンテナー) によって管理されるビュー コントローラー内にあります。私はこれらのブラウザを 4 つ以下しかメモリに保持していません。
クラッシュ ログ、またはクラッシュの原因について何かありますか?
これは、Web スレッドのクラッシュ ログです。
