分节表视图
步骤
创建一个iOS工程
删除storyboard中View Controller Scene 中的View Controller，再从对象库拖入一个Table View Controller到设计界面
打开Table View Controller属性检查器，勾选Is Initial View Controller选项，否则应用启动后是黑屏
将ViewController类的父类由UIViewController改为UITableViewController
打开View Controller的属性选择器在Class列表中选择ViewController
UITableViewController默认以注册UITableViewDataSource和UITableViewDelegate协议，不需要再注册

静态表视图
步骤
创建一个iOS工程，使用Table View Controller作为表视图控制器
选择Table View，打开属性检查器，从Content下拉列表中选择Static Cells，将Section的值为设为3.，从Style下拉列表中选择Grouped
选择第一个Table View Section，将Rows值设为2，即该节中包含两个单元格，分别拖入一个TextField到两个单元格中
选择第二个Table View Section，将Rows值设为1，拖入一个Button到单元格中
选择第二个Table View Section，将Rows值设为1，拖入一个Lable到单元格中
