UIStoryboard Couldn't find view controller with identifier

问题

I have an ios application using storyboards with a bunch of view controllers.

After Adding a new ViewController, and configured the identify (Storyboard ID)

I try to instantiate the new ViewController with the following code:

SurveyNewViewController *newSurvey = [[self storyboard] instantiateViewControllerWithIdentifier:@"newSurveyView"];
[self presentViewController:newSurvey animated:YES completion:nil];

Everything seems to be right, but when running the application on the simulator it crashes:

** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason:   
'Storyboard (<UIStoryboard: 0xa340fa0>) doesn't contain a view controller 
with identifier 'newSurveyView''

Is there any possible explanation for this? I have used this same approach in different places on the system and it works well.

回答1:

Try remove your app from iPhone Simulator, clean project and build, after run your project.

回答2:

Try with that :

[[UIStoryboard storyboardWithName:@"StoryboardNameOfnewSurveyView" bundle:nil] instantiateViewControllerWithIdentifier:@"newSurveyView"];

If it works, I think [self storyboard] don't give you the right object ;).

回答3:

Set Storyboard ID as this is use in Xcode 8.0 and check the Use Storyboard ID option. Also check the Class field is set in Storyboard to that ViewController.
