[Swift] Storyboardを使わずに画面遷移をすると、遷移先が黒画面になるときやstoryboard doesn't contain a view controller with identifier 'って言われるとき。 ref: http://qiita.com/tsumekoara/items/c8cb6f815e6dc0b6beba

file2.swift

let storyboard = UIStoryboard(name: "STORYBOARD_NAME", bundle: nil)
let nextVC = storyboard.instantiateViewControllerWithIdentifier("STORYBOARD_ID_OF_VC_CLASS") as! UIViewController
navigationController?.pushViewController(nextVC, animated: true)

file3.txt

storyboard doesn't contain a view controller with identifier 'foo''

navigationありのとき

let nextVC = FooVC() as UIViewController
nextVC.modalTransitionStyle = UIModalTransitionStyle.PartialCurl
navigationController?.pushViewController(nextVC, animated: true)

例えば

// set next VC
let nextVC: UIViewController = FooVC()

// set animation
nextVC.modalTransitionStyle = UIModalTransitionStyle.PartialCurl

// transition
self.presentViewController(nextVC, animated: true, completion: nil)
