EXC_BAD_ACCESS與垃圾收集崩潰後運行小時

我有一個應用程序，其中幾個視頻隨機顯示，一切都很好，工作很好。由於他們編程循環遍歷相同的代碼，我覺得很奇怪，只是突然停下來。下面的錯誤信息是關於什麼的？EXC_BAD_ACCESS與垃圾收集崩潰後運行小時

但經過數小時後，它崩潰。第一次在碰撞前跑了13個小時，今晚在11小時後墜毀。

我認爲你需要向我們展示你一次又一次地遍歷代碼。 – JeremyP 2011-03-01 09:11:45

當然對不起，早上的疲倦幾乎沒有 – tobros91 2011-03-01 09:27:44

的崩潰深深地嵌在了AppKit的代碼。該窗口正忙於重繪其視圖層次結構的一部分。在這個過程中，它使用一個（私有）_NSDisplayOperation對象，它響應上述rectSetBeingDrawnForView:選擇器。

堆棧跟蹤看起來像AppKit嘗試向錯誤收集的顯示操作對象發送消息。崩潰可能與您的代碼無關。

那麼，你能做些什麼呢？
