我們需要更多一點，你能給我們從控制檯的錯誤信息？當然是 – rckoenes 2011-03-16 16:23:53

。在2-3小時內，我會添加錯誤信息，謝謝你的幫助。 – Andreich 2011-03-16 17:20:10

出於某種原因，從這個問題不清楚，OverviewController的一個實例是在地方的UIApplicationDelegate應該的。可能是與MainWindow xib中的插件混淆？在Main Windo xib中，應將UIApplication實例中的「委託」插座分配給UIApplicationDelegate。是這樣嗎？

我這樣說是因爲錯誤是由applicationWillResignActive方法引起的：在OverviewController上調用並未找到。 applicationWillResignActive：是應用程序委託在鎖定之前調用的方法。
