尝试执行"推送"时出现一个奇怪的错误UIViewController上的序列。
我已将两个UINavigationControllers嵌入到根UIViewController中。
我基本上试图在>按下按钮,它会推送到"视图控制器。"
为什么我收到以下错误的任何想法?:
*** Terminating app due to uncaught exception 'NSGenericException', reason: 'Push segues can only be used when the source controller is managed by an instance of UINavigationController.'
这是我的故事板:

我像这样进入RecordViewController:
RecordViewController *record = [self.storyboard instantiateViewControllerWithIdentifier:@"RecordView"];
[self presentViewController:record animated:YES completion:nil];
答案 0 :(得分:1)
如果要将视图控制器推送到显示的视图控制器,则显示的视图控制器必须是UINavigationController
。在您的情况下,给最左边的导航控制器一个标识符(即RecordNavigationController
)并将您的代码转换为:
UINavigationController *recordNavigationController = (UINavigationController*)[self.storyboard instantiateViewControllerWithIdentifier:@"RecordNavigationController"];
[self presentViewController:recordNavigationController animated:YES completion:nil];
