我有一個示例應用程序在模擬器上正常工作，但在設備上崩潰。我從Organizer的控制檯上獲得以下輸出。它在很短的時間內崩潰。iOS低內存崩潰問題，但使用非常低的內存 - 使用儀器檢查
使用儀器，內存泄漏，我看到內存使用量約爲2-3 mb。使用內存分配，我發現大約8-9mb用於內存分配，而虛擬機跟蹤器中沒有任何內容。
控制檯輸出如下。任何人都可以建議做什麼？

好的，所以試着在模擬器上進行分析。似乎它需要，在某些時候，70-80mb之前回到2-3 mb ....也許這就是問題... – Ahsan 2012-04-26 19:27:17
也沒有骯髒或駐留使用虛擬機跟蹤。 – Ahsan 2012-04-26 19:45:38
