我需要一些幫助。我得到這個錯誤「NSInvalidArgumentException」，原因：' - [__ NSArrayM isEqualToString：]「當我試圖運行我的應用程序。任何人都可以識別我的錯誤？ 這是我的代碼...Xcode NSInvalidArgumentException'，原因：' - [__ NSArrayM isEqualToString：]錯誤

哪行代碼會產生此異常？爲此，請在objc_exception_thrown [tutorial here]上添加一個斷點（http://stackoverflow.com/questions/1163981/how-to-add-a-breakpoint-to-objc-exception-throw）。運行應用程序並在崩潰後打開調試器窗口。在那裏你應該找到當前堆棧跟蹤，你應該能夠看到生成異常的代碼行是什麼。 – 2011-02-17 15:42:58
