iOS开发学习之#简单通讯录的制作#

（1）创建一个项目telephoneBook

（2）打开Main.storyboard文件，从视图库图拖一个Tab bar Controller标签栏控制器到画布中。

（3）在工具栏中，选择show the Attributes inspector图标，在View controller下，选择Is Initial View Controller。

（4）将画布中的原有的view controller视图控制器删掉，再将Tab Bar controller标签栏控制器关联view controller-Item 1和view controller-Item2视图控制器的视图删除。

（5）从视图库中拖一个Navigation controller导航控制器到画布中。

（6）将Tab Bar Controller标签栏控制器关联视图变为Navigation Controller导航控制器。
