连线的话，拖动之后选择 Pressent Modally就可以了
代码
let storyboard = UIStoryboard(name: "Main", bundle: nil)
var modal = storyboard.instantiateViewControllerWithIdentifier("Modal")
self.presentViewController(modal, animated: true, completion: nil)
self.dismissViewControllerAnimated(true, completion: nil)
在模态窗中没有 Navigation Item ，手动添加也没用
