目前我遇到以下错误:
2014-07-17 19:53:49.600 mobile-app[14483:60b] *** Assertion failure in -[UIStoryboardUnwindSegueTemplate _perform:], /SourceCache/UIKit/UIKit- 2935.138/UIStoryboardUnwindSegueTemplate.m:78
2014-07-17 19:53:49.602 mobile-app[14483:60b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not find a view controller to execute unwinding for <OptionsTabBarViewController: 0x16d75ad0>'
我尝试通过Touch up Inside对RootViewController进行Segue,然后执行SelectedIndex:1;
我在optionsTabBarViewController上有以下代码:
- (IBAction)cancelCall:(UIStoryboardSegue *)segue {
[self setSelectedIndex:1];
}
在StoryBoard上,我将ViewController与Exit链接在一起是图像:
这就是我如何在ViewController上调用Segue:
[self performSegueWithIdentifier:@"history_vc" sender: self];
不明白为什么它没有执行Segue并给我下面显示的错误。
这是我的NavigationController Hirarchy:
