Multiview

• 新建3个ViewController的类
• 新建main.stroyboard，并配置好相应的布局（编辑界面，连接视图与类，ViewController的Storyboard ID，连接3个Button的响应事件）
• 删除app delegate中didFinishLaunchingWithOptions中的代码
• 修改SwitchViewController.m代码（viewDidLoad，didReceiveMemoryWarning，switchButton的响应函数（包括动画））
• 修改BlueViewController.m和YellowViewController.m，添加button响应函数
