普通viewcontroller切換

let storyBoard = UIStoryboard(name:"Main", bundle: nil)
let nextScene = storyBoard.instantiateViewController(withIdentifier: "Scene_enemy") as! Scene_enmey
self.present(nextScene, animated: false, completion: nil)

導(dǎo)航navigatecontrolller切換

let storyBoard = UIStoryboard(name:"Main", bundle: nil)
let nextScene = storyBoard.instantiateViewController(withIdentifier: "Scene_enemy") as! Scene_enmey
self.navigationController?.pushViewController(nextScene, animated: false)

添加過渡動(dòng)畫

let animation = CATransition()
animation.duration = 0.4;
animation.timingFunction = CAMediaTimingFunction.init(name: CAMediaTimingFunctionName.easeInEaseOut)
animation.type =  CATransitionType.moveIn;
animation.subtype = CATransitionSubtype.fromRight;
self.view.window?.layer.add(animation,forKey: nil)

pushViewController / present 之前調(diào)用
