代碼不再在OS4.3中工作，但在5.0中罰款（用於正常工作）

Question

奇怪的錯誤。我的代碼是用Xcode 3編寫的，它在4.4中正確加載沒有錯誤。

最近，它開始在OS 4.3或更低版本中運行，但在5.0和5.1版本中運行良好。我已經做了幾個星期的更新我的應用程序，所以我不知道它在哪裏出了問題（我在測試時使用了當前的模擬器5.1，所以我甚至沒有想過在每次試用之後嘗試其他模擬器）。

這是我的錯誤日誌，但我無法弄清楚是什麼導致崩潰。應該注意的是，當4.3或更低版本啓動時，我得到「位置服務不可用」，但在5.0或更高版本中啓動。它試圖加載一個有表格的視圖時崩潰了。這是我的調試器信息...任何想法？

看起來您使用界面構建器添加了手勢識別器，該功能僅適用於ios5等。
