現在の引数レジスタにあるセレクタ名：isEqual：
私はOSXアプリのバグをつぶすことで、うまく動かないような支援を探しています。次のエラーがログに記録されます。
Selector name found in current argument registers: isEqual:
しかし、ログは非常に役に立たないので、それがどこから来ているのかを知ることができません。また、自分のテストシステムではこれを再現できませんが、一部のベータテスターマシンではかなり発生しているようです。これは10.9でのみ発生するようです。
クラッシュのログファイルは次のとおりです。

クラッシュレポートの文字列_Selector name found in current argument registers: isEqual:_は、実際にはHockeySDKからのものであり、objc_msgSend()が呼び出そうとしていた最後のセレクター名を示しています。これは、クラッシュレポートに次の文字列を示すOS Xと同じです：objc_msgSend() selector name: isEqual:。
SDKでこのメッセージを改善し、現在の着信メッセージのバックエンドで何ができるかを確認します。
したがって、クラッシュはHockeySDKが原因ではありません。
クラッシュの理由は、_objc_msgSend_（スレッド10フレーム0）が無効なオブジェクトでisEqualを呼び出そうとしたため、例外タイプSIGSEGV（ http://en.wikipedia.org/wiki/Segmentation_fault ）。これは、フレーム4の_[NSButtonCell _currentTitle]_によってトリガーされました。
したがって、テーブルビューとセルのメモリ管理を確認することをお勧めします。特に、titleをNSButtonCellに割り当てる場合。
