如何在Swift,iOS中使用xib文件初始化UIView类

我有一个类叫MyClass是UIView的子类，我想用xib文件初始化。我不知道如何用名为View.xib的xib文件初始化这个类

class MyClass: UIView{

     //init(coder aDecoder: NSCoder){} ?? 
}

我测试了这个代码，它的工作伟大

class MyClass: UIView {

    class func instanceFromNib() -> UIView {
        return UINib(nibName: "nib file name",bundle: nil).instantiateWithOwner(nil,options: nil)[0] as UIView
    }


}

初始化视图并使用它如下

var view = MyClass.instanceFromNib()
    self.view.addSubview(view)

要么

var view = MyClass.instanceFromNib
    self.view.addSubview(view())

UDATE Swift 3.x

class func instanceFromNib() -> UIView {
    return UINib(nibName: "nib file name",bundle: nil).instantiate(withOwner: nil,options: nil)[0] as! UIView
}
