我正在爲Titanium for Android和IOS做一個應用程序。當我在應用程序中導航很多時,我有一個隨機異常,應用程序崩潰。如何理解EXC_BAC_ACCESS(SIGSEGV)KERN_INVALID_ADDRESS日誌?
我怎麼知道問題在哪裏?
該應用程序是有點複雜的解釋:
它有兩個窗口,第一窗口是「家」的觀點,即只有在縱向模式下,當我點擊進入另一種觀點,我關閉第一個窗口,我打開另一個窗口,然後添加一個視圖,其內容顯示在此窗口中。內容視圖使用不同的網址加載相同的網頁視圖。
該應用程序加載好,我可以瀏覽不同的意見和窗口好。但是,當我導航了很多,最後我有一個EXC_BAC_ACCESS(SIGSEGV)和KERN_INVALID_ADDRESS
這隻發生在設備上(在模擬器上它工作正常)與iPad操作系統5.1.1和操作系統7.0.2。
這是日誌,其中螺紋崩潰:

我也有其他的線程和關於二值圖像信息的日誌。如果它有用,我可以粘貼它。
我怎麼知道問題的原因是什麼以及問題在哪裏?
非常感謝您
您需要用符號表示該堆棧跟蹤。 –
我該怎麼做?謝謝 –
