Answer 1

whenever you want to load a VC as the way you mentioned, you need two things.

Thing 1: Specific storyboard ID. you will find this by:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Your_Storyboard_Id" bundle:nil];

In my case this is Main

Thing 2:

You need your View Controller id. Just click on the View Controller you want to go from storyboard and give a suitableName there.

Then invoke this like:

UIViewController * yourVC = [storyboard   
instantiateViewControllerWithIdentifier:@"YourVC_ID"] ;

And if you want to present it modally you already did this. :)

[self presentViewController:yourVC animated:YES completion:nil];

Answer 2

Try this

UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
FeedBackViewController * feedbackVC = [story   instantiateViewControllerWithIdentifier:@"FeedBackView"] ;
[self presentViewController:feedbackVC animated:YES completion:nil];

Where FeedBackView is your storyboard id of FeedBackViewController.

Answer 3

Check these things

Check the identifier of the viewcontroller, if it is the same that you mentioned in storyboard

Make sure that your view object is not nil. Set a breakpoint on that line and on the debug area at the bottom see whether the object is not nil. If it is nil then problem lies in the storyboard connection

If your current viewcontroller is not launched from storyboard then get storyboard object like this :

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController * feedbackVC = [storyboard   instantiateViewControllerWithIdentifier:@"FeedBackView"] ;
[self presentViewController:feedbackVC animated:YES completion:nil];
