下面演示了两种创建标签页的方法。

1，使用storyboard设计标签页
(1)新建一个Simple View Application，然后删除原来的View Controller并拖入一个Tab Bar Controller，默认就带有两个标签页，每个标签页都在一个View Controller里。
(2)项目新建为Tabbed Application模板也可实现上面的效果。
(3)如果想要添加新的标签页，可以在storyboard里拖入更多的View Controller，每个View Controller放入一个Tab Bar Item。然后建立Tab Bar Controller和新建的View Controller之间的segue关联。即按住Ctrl键，拖动Tab Bar Controller到View Controller，在弹出的上下文菜单中选择View Controller即可。
