Question

我有两个TableViewControllers，两个原型单元的布局是相同的。是否可以提取布局以便我不需要维护多个副本？

Answer 1

您可以将这些原型单元移动到xib文件中，并在每个tableview上注册UINib。

Answer 2

通过xib使用单元格，您可以重用其他表格

要创建xib，右键单击xcode上的项目选择新文件，然后选择UserInterface从中选择视图并保存名称

然后为xib文件的类五个适当的表视图单元类并在表视图单元格中创建控件的出口

在表视图控制器上加载nib文件在表视图控制器上声明这两行viewdidload函数

  @property (nonatomic, strong) UIScrollView *scrollView;
  @property (strong, nonatomic) IBOutlet UIScrollView *scrollVw;
