iOS 8 Storyboard/主界面

Question

我正在创建一个 iOS 8 应用程序。我有两个适用于 iPhone 和 iPad 的 Storyboard。 iPad.storyboard 设置为主界面。 我的问题是每次我在 iPhone 设备上运行时，iPad.storyboard 仍然被调用。

有没有办法自动检测特定设备的 Storyboard？

//If you are looking for a swift solution
   if(UIDevice.currentDevice().userInterfaceIdiom == UIUserInterfaceIdiom.Pad) {
       //iPad
      var iPadBoard: UIStoryboard!
      iPadBoard = UIStoryboard(name: "iPad", bundle: nil)
      let viewcontroller : UIViewController = iPadBoard.instantiateViewControllerWithIdentifier("iPad") as UIViewController
      self.window!.rootViewController = viewcontroller
    }
    else {
       //iPhone
      var iPhoneBoard: UIStoryboard!
      iPhoneBoard = UIStoryboard(name: "iPhone", bundle: nil)
      let viewcontroller : UIViewController = iPhoneBoard.instantiateViewControllerWithIdentifier("iPhone5") as UIViewController
      self.window!.rootViewController = viewcontroller
    }
