Recently my app is crashing when the app switch to the next ViewController.

this is the prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

    ShowInfoViewController *secondViewController = (ShowInfoViewController *)segue.destinationViewController;

this is how i call the method : 

        [self performSegueWithIdentifier:@"infoseg" sender:self];

in the interface builder i have a segue with the same identifier as well.

any idea?

this is the log's Print : 

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Receiver (<ViewController: 0x1dda97d0>) has no segue with identifier 'infoseg''

如果您的目标视图控制器位于导航控制器中，您可能想看看这个问题：How to set the delegate with a storyboard。

编辑：从错误看来，您尝试执行的 segue 未附加到您开始的视图控制器。尝试删除序列并将其从您的代码所在的视图控制器拖到界面构建器内部的 ShowInfoViewController 中。

有同样的问题。意识到我正在 AppDelegate.m 和 Storyboard 中设置根控制器。删除 AppDelegate.m 中的代码并修复它。

我有一个类似的问题 - 原来我在故事板上的 segue 标识符上有一个尾随空格。

例如。'SequeIdentifier' - 当然这在 XCode 中很难看到
