您可以在 var c $ c> VCB viewController并将数据注入此属性

You just can declare a var in your VCB viewController and inject data to this property

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("vcB") as VCB;

vc.yourData = SOME_DATA

rootController!.presentViewController(vc, animated: true, completion: nil)


class VCB: UIViewController {

var yourData: AnyObject?

required init?(coder aDecoder: NSCoder){
    super.init(coder: aDecoder)
  }

}
