使用Swift，如何使用StoryBoards创建另一个UIViewController

I have a viewcontroller that hold a button for now, and I want to create a new viewcontroller and add his view over the current one

我有一个viewcontroller，暂时按住一个按钮，我想创建一个新的viewcontroller并将其视图添加到当前的一个

So far I did this:

到目前为止，我这样做了：

class ViewController : UIViewController
{
    var myController: MyController = MyController.controller()

    init(coder aDecoder: NSCoder!)
    {
        super.init(coder: aDecoder)
    }

    init(nibName nibNameOrNil: String!, bundle nibBundleOrNil: NSBundle!)
    {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
    }

    override func viewDidLoad()
    {
        super.viewDidLoad()
        self.view.addSubview(self.myController.view)
    }

    @IBAction func buttonPressed(sender : AnyObject)
    {

    }
}

in MyController I did a singleton (I hope I did it right)

在MyController中我做了一个单身（我希望我做对了）

class MyController : UIViewController
{

    init(coder aDecoder: NSCoder!)
    {
        super.init(coder: aDecoder)
    }

    init(nibName nibNameOrNil: String!, bundle nibBundleOrNil: NSBundle!)
    {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
    }

    class func controller() -> MyController
    {
        var once : dispatch_once_t = 0
        var sharedInstance: MyController?

        dispatch_once(&once, { sharedInstance = MyController()})

        return sharedInstance!
    }
}

the behavior I got is this, if I DON'T call the

我得到的行为就是这个，如果我不打电话给

self.view.addSubview(self.myController.view)

self.view.addSubview（self.myController.view）

everything works fine, if I did, the button in the center is not anymore recognizing the touches, it is like it has something over that intercept the touch, what is wrong here? what I'm missing?

一切正常，如果我这样做，中心的按钮不再能识别触摸，就像它有一些拦截触摸的东西，这里有什么问题？我错过了什么？

You did it wrong. Singleton is not required here. If you are using storyboard, the below line

你做错了。这里不需要单身人士。如果您正在使用故事板，请在下面一行

var myController: MyController = MyController.controller()

could be

可能

var myController: MyController = self.storyboard.instantiateViewControllerWithIdentifier("MyViewController")

Then before adding sub view set the frame of the self.myController.view

然后在添加子视图之前设置self.myController.view的框架

self.myController.view.frame = CGRectMake(0, 0, 320, 200); // or what ever frame you want
