我的标签栏应用程序有问题。一切运作良好,但如果我发送模拟器命令“锁屏”调试器控制台说应用程序崩溃。它能是什么?

出于某种原因,从问题中不清楚,概述了一个概念控件的实例应该是UIApplicationDelegate的实例。可能是MainWindow xib中的插座混音?在Main Windo xib中,应将UIApplication实例中的“delegate”插座分配给UIApplicationDelegate。是这样的吗?

我这样说是因为错误是由方法applicationWillResignActive引起的:在OverviewController上被调用而没有找到。 applicationWillResignActive:是应用程序在锁定之前在应用程序委托中调用的方法。
