iphone - 应用程序仅在 ipad 模拟器 4.3 上崩溃

Question

您好，我的应用程序仅在 iPad 模拟器 4.3 上崩溃。该应用程序在 iPad 模拟器 5.0、iPhone 模拟器 4.3 和 iPhone 模拟器 5.0 中运行良好。知道是什么原因造成的吗？错误如下:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '-[UIViewController _loadViewFromNibNamed:bundle:] loaded the "HomeViewController" nib but the view outlet was not set.'

Answer 1

在您的 nib 中，您需要将 File Owner 类设置为 HomeViewController，然后将顶级 View 连接到 File Owner 的 view outlet。
