UIStoryboard: What's the Correct Way to Get the Active Storyboard?
In case you want to get the active storyboard for a viewController, there's a storyboard property. This is how I solved it, instead of making a new instance:
LoginViewController *vc = [navController.storyboard instantiateViewControllerWithIdentifier:@"firstLaunch"];
[navController presentModalViewController:vc animated:YES];
In Swift you'd call:
let loginViewController = navigationController?.storyboard?.instantiateViewController(withIdentifier: "firstLaunch") as! LoginViewController
navigationController?.present(loginViewController, animated: true, completion: nil)
You could also be a lot safer by using guards against the navigation controller and the storyboard. I've used as!
so as to guarantee that you're getting a LoginController.
OK. As my comment above indicates, I found the answer to the (badly phrased question):
I wanted to be able to get the main (not active) storyboard, as I'm not using multiple storyboards per incarnation. I'm using the standard model of 1 storyboard for iPhone, and 1 for iPad. I just wanted the cleanest way to get the storyboard, so that I could use it to generate a view controller.
I found the answer in this post on Stack Overflow, and implemented it with the following code:
UIStoryboard *st = [UIStoryboard storyboardWithName:[[NSBundle mainBundle].infoDictionary objectForKey:@"UIMainStoryboardFile"] bundle:[NSBundle mainBundle]];
In Swift, you'd use the following syntax:
let storyboard = UIStoryboard(name: "Main", bundle: nil)
Note that passing nil
to bundle
will make the call refer to your main bundle automatically.
If you're in a view controller that you have on the Storyboard and want to instantiate the Storyboard from there directly, you can just do:
let storyboard: UIStoryboard? = self.storyboard // call this inside a VC that is on the Storyboard
Note that in the last case, self.storyboard
will return an optional Storyboard (Storyboard?
), so if you'd like to use it unwrap it like so:
if let storyboard = self.storyboard {
// access storyboard here
}
