关于委托的Objective-C设计模式问题

与创建许多类不同,更简单的解决方案是将类划分为不同的类别:

@interface MyViewController : UIViewController {
  ...
}
...
@end


@interface MyViewController (TableStuff) <UITableViewDataSource, UITableViewDelegate>
// methods related to table stuff
@end


@interface MyViewController (SearchStuff) <UISearchBarDelegate>
// methods related to table stuff
@end
