UITableView就像gridView一样
我有一个NSMutableArray，我在其中存储从服务url中获取的项目并完成解析。我在UITableView中显示数组项，就像gridview一样（每行4列，没有行取决于数组计数）。它是比如显示一周内可用的所有在线考试时间。所以我必须逐个加载每一天的时间，如果所有的时段都保留在特定的一天，那么应该显示那天的msg（没有可用的插槽）然后在tableView中加载下一个数组项。但我只能获得最后一天的时段。
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，我使用相同的tableview并将每个数组项目分别加载到特定日期。但我只能获得最后一天的时间
我怎样才能使用这种特殊格式？
对于使用哪种控件或如何使用相同的tableView，任何建议/建议都是值得注意的。

首先，您最好使用UICollectionView来代表网格而不是UITableView。它很清洁。
接下来，在您尝试在一行中显示4个网格的特定情况下，您需要在% cellForRow委托中使用模UItableView运算符。还将uitableview委托中的项目数量调整为（totalitems）/ 4。我打赌还有一些我忘记提及的事情。
我强烈建议你花些时间迁移到UICollectionView更清洁......
