  myroot.delegate=self;

    [self.windowmakeKeyAndVisible];

    return YES;

}

- (void)tabBarController:(UITabBarController *)tabBarController

 didSelectViewController:(UIViewController *)viewController

{

    //tabBarController.delegate = self;

    NSLog(@"User selected %@ from the tabbar",viewController);

   // viewController.view.backgroundColor=[UIColor blackColor];

    if ([viewController isKindOfClass:[otherViewControllerclass]]) {

        otherViewController* view=(otherViewController*)viewController;

        NSString *path = [NSStringstringWithFormat:@"%@/Documents/save.dat",NSHomeDirectory()];

        NSData *data2 = [NSDatadataWithContentsOfFile:path];//读取文件

        //  view.datalist=[[NSMutableArray alloc]init];

        view.datalist = [NSKeyedUnarchiverunarchiveObjectWithData:data2];//反序列化

        NSLog(@"herehrer...%d",[view.datalistcount]);

        [view.table reloadData];

    }

    这是设置每次点击前刷新数据源的操作，子啊appdelegate。m中设置的，没想到还可以这样做。
