storyboard的应用

1. 通过stroyboard id引用页面

UIStoryboard *storyBoard=[UIStoryboard storyboardWithName:@"购物车" bundle:nil];
[self.navigationController pushViewController:[storyBoard instantiateViewControllerWithIdentifier:@"my-test"] animated:YES];

2. 通过stroyboard 构建tabbar ，并新建类IndexTabBarController，并storyboard的tabbar类，设置为IndexTabBarController,监听事件代理，可改变顶部标题

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item{
    self.navigationItem.title = item.title;
}

3. 某个页面，不需要顶部导航，则在页面将要显示时，隐藏该导航，将要离开时，要恢复导航

- (void) viewWillAppear:(BOOL)animated{
    [self.navigationController setNavigationBarHidden:YES];
}

-(void) viewWillDisappear:(BOOL)animated{
    [self.navigationController setNavigationBarHidden:NO];
}

4. 解析plist文件

    NSString *path = [[NSBundle mainBundle] pathForResource:@"地址" ofType:@"plist"];
    NSDictionary *dic = [NSDictionary dictionaryWithContentsOfFile:path];

5. 表格操作

//注册单元格
 [self.tableView registerClass:UITableViewCell.class forCellReuseIdentifier:@"reuseIdentifier"];
 
 //使用单元格
 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"reuseIdentifier" forIndexPath:indexPath];
    if(!cell){
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"reuseIdentifier"];
    }
    cell.textLabel.text = self.data[self.keys[indexPath.section]][indexPath.row];
    return cell;
}
