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视图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。
