我只是推送一个UITableviewController导航堆栈。代码在 iOS 4.3 和 5 中都可以正常工作，但在 iOS 6 中崩溃。例外情况是：

由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“-[UIViewController _loadViewFromNibNamed:bundle:] 加载了“MenuController”笔尖，但未设置视图出口。

我知道未设置视图出口时会引发此异常。如图所示，出口由 IB 自动设置，但仍然相同。我究竟做错了什么？

推送控制器的简单代码：

MenuController *menu = [[MenuController alloc] initWithStyle:UITableViewStylePlain];
    menu.title = @"Watches";
    menu.MenuToBeDisplayed = @"main menu";
    [self.navigationController pushViewController:menu animated:YES];

在此处输入图像描述

编辑：

我已经删除了 nib 文件和initWithNibName:方法，但从昨天开始我仍然收到这个愚蠢的异常。这会让我发疯:(

和

MenuController *menu = [[MenuController alloc] initWithStyle:UITableViewStylePlain];

您根本没有使用您的 xib 文件，因为您需要使用 xib 来初始化控制器

initWithNibName:bundle:代替initWithStyle:

然后像这样在xib上设置控制器的类

设置 xib 的控制器自定义类
