iphone - UITableView 类似于 gridView

Question

我有一个 NSMutableArray，我在其中存储从服务 url 获取的项目并完成解析。我在 UITableView 中显示数组项目，其行为类似于 gridview(每行 4 列，行数取决于数组计数)。这有点像显示一周内所有可用的在线考试时段。所以我必须一个一个地加载每天的时间，如果所有的插槽都是为特定的一天保留的，那么应该显示当天的消息(没有可用的插槽)，然后加载下一个tableView 中的数组项。但我只能获得最后一天的可用时段。

我必须采用以下格式:

10/1/2013

10:00 AM    11:00 AM   12:00 PM   1:00 PM
2:00 PM

11/1/2013

11:00 AM     12:00 PM   1:00 PM    2:00 PM 

12/1/2013

   No slot available

13/1/2013

10:00 AM    11:00 AM   12:00 PM   1:00 PM
2:00 PM     3:00 PM

............

截至目前，我正在使用相同的表格 View 并分别加载特定日期的每个数组项。但我只能获得最后一天的时间

我怎样才能获得这种特定格式？

任何关于使用哪个控件或如何使用同一个 tableView 的建议/建议都是显而易见的。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

}   

这是我所做的代码。

尝试我的以下代码中的一些代码...删除一些对您无用的其他代码..
我有这种类型的要求，我用我的波纹管代码和逻辑完成了它......还看到我认为你想要类似的图像......

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [_grids count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return 1;
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{ 
    NSArray* items = [_grids objectAtIndex:indexPath.section];
    
    //number of rows in one grid if one row will have 4 items
    //    float totalRow = ceilf(items.count/4);
    int total = [items count];
    
    float f = (float)total /4;
    int numberOfGridRows = ceilf(f);
    NSLog(@"\n\n Rows :>> %d",numberOfGridRows);
    //height of table row
    return numberOfGridRows * 36.0 + 120;
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
