Comment pourrais-je référencer le scénario principal dans mon application par programme rapidement?

Comment pourrais-je référencer le scénario principal dans mon application par programme rapidement? J'ai cherché une référence dans le délégué de l'application, mais je n'en ai pas trouvé jusqu'à présent.

Oh oups j'ai trouvé la réponse ...

Dans un autre contrôleur de vue connecté au storyboard, vous pouvez simplement utiliser:

self.storyboard?

Ou tout objet peut obtenir un storyboard en référençant son nom et son bundle

let storyboard = UIStoryboard(name: "storyboardNameHere", bundle: nil) //if bundle is nil the main bundle will be used

C'est facile. Quand j'ai rencontré un problème similaire, j'ai écrit une classe qui peut obtenir toutes les ressources du bundle principal. 

//Generate name of the main storyboard file, by default: "Main"
var kMainStoryboardName: String {
    let info = NSBundle.mainBundle().infoDictionary!

    if let value = info["TPMainStoryboardName"] as? String
    {
        return value
    }else{
        return "Main"
    }
}

public class TPBundleResources
{
    class func nib(name: String) -> UINib?
    {
        let nib = UINib(nibName: name, bundle: NSBundle.mainBundle());
        return nib
    }

    //Main storybord
    class func mainStoryboard() -> UIStoryboard
    {
        return storyboard(kMainStoryboardName)
    }

    class func storyboard(name: String) -> UIStoryboard
    {
        let storyboard = UIStoryboard(name: name, bundle: NSBundle.mainBundle())
        return storyboard
    }

    //Obtain file from main bundle by name and fileType
    class func fileFromBundle(fileName: String?, fileType: String?) -> NSURL?
    {
        var url: NSURL?

        if let path = NSBundle.mainBundle().pathForResource(fileName, ofType: fileType)
        {
            url = NSURL.fileURLWithPath(path)
        }

        return url
    }

    class func plistValue(key:String) -> AnyObject?
    {
        let info = NSBundle.mainBundle().infoDictionary!

        if let value: AnyObject = info[key]
        {
            return value
        }else{
            return nil
        }
    }
}


public extension TPBundleResources
{
    //Obtain view controller by name from main storyboard
    class func vcWithName(name: String) -> UIViewController?
    {
        let storyboard = mainStoryboard()
        let viewController: AnyObject! = storyboard.instantiateViewControllerWithIdentifier(name)
        return viewController as? UIViewController
    }

    class func vcWithName(storyboardName:String, name: String) -> UIViewController?
    {
        let sb = storyboard(storyboardName)
        let viewController: AnyObject! = sb.instantiateViewControllerWithIdentifier(name)
        return viewController as? UIViewController
    }

    //Obtain view controller by idx from nib
    class func viewFromNib(nibName: String, atIdx idx:Int) -> UIView?
    {
        let view =  NSBundle.mainBundle().loadNibNamed(nibName, owner: nil, options: nil)[idx] as! UIView
        return view
    }

    class func viewFromNib(nibName: String, owner: AnyObject, atIdx idx:Int) -> UIView?
    {
        let bundle = NSBundle(forClass: owner.dynamicType)
        let nib = UINib(nibName: nibName, bundle: bundle)
        let view = nib.instantiateWithOwner(owner, options: nil)[idx] as? UIView
        return view
    }

    class func viewFromNibV2(nibName: String, owner: AnyObject, atIdx idx:Int) -> UIView?
    {
        let view =  NSBundle.mainBundle().loadNibNamed(nibName, owner: owner, options: nil)[idx] as! UIView
        return view
    }
}

Voici des exemples simples:

//Get a main storyboard
TPBundleResources.mainStoryboard()

//Get view controller form main storyboard
TPBundleResources.vcWithName("MyViewController")

//Get view from MyView.nib at index 0
TPBundleResources.viewFromNib("MyView", atIdx: 0)

//Get plist value by key
TPBundleResources.plistValue("key")
