If you want to present a new view in the same storyboard,
In CurrentViewController.m,
#import "YourViewController.h"
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
YourViewController *viewController = (YourViewController *)[storyboard instantiateViewControllerWithIdentifier:@"YourViewControllerIdentifier"];
[self presentViewController:viewController animated:YES completion:nil];
To set identifier to a view controller, Open MainStoryBoard.storyboard. Select YourViewController View-> Utilities -> ShowIdentityInspector. There you can specify the identifier.
