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];
