这几天都有一些任务要跟, 把ios的学习拉后, 看看要抓紧咯, 看看轮到的学习的是UITableView。

BIDAppDelegate.h

#import 
     
      @class BIDViewController;@interface BIDAppDelegate : UIResponder 
      
       @property (strong, nonatomic) UIWindow *window;@property (strong, nonatomic) BIDViewController *viewController;@end

BIDViewController.h

      @interface BIDViewController : UIViewController
      
       @property (copy, nonatomic) NSArray *dwarves;@end
