本節學習內容：
1.分欄控件器的代理使用
2.分校控制器的協義方法
3.分欄控制器的高級使用
分欄控制器高級協義函數
willBeginCustomizingViewcontrollers:即將顯示編輯方法
willEndCustomizingViewControllers:媽將結束編輯方法
didEndCustonmizingViewControllers:已經結束編輯方法
didSelectViewController:選中控制器切換方法
創建6個視圖控器，分別為VCFirst,VCSecond,VCThird,VCFour,VCFive,VCSix都繼承于UIViewController
