Iphone 类似gridView的UITableView
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，就像gridview4列一样，每行的行数取决于数组计数。这类似于显示一周内所有可用的在线考试时间。因此，我必须逐个加载每天的计时，如果全部加载的话插槽是为特定的一天保留的，然后应显示该天的消息“无可用插槽”，然后在tableView中加载下一个数组项。但我只能得到最后一天的空位 我必须采用以下格式：Iphone 类似gridView的UITableView,iphone,ios,objective-c,uitableview,uicollectionview,Iphone,Ios,Objective C,Uitableview,Uicollectionview,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，就像gridview4列一样，每行的行数取决于数组计数。这类似于显示一周内所有可用的在线考试时间。因此，我必须逐个加载每天的计时，如果全部加载的话插槽是为特定的一天保留的，然后应显示该天的消息“无可用插槽”，然后在tableView中加载下一个数组项。但我只能得到最后一天的空位 我必须采用以下格式： 10/1/2013 10:00 AM 11:00 AM 12

这是我编写的代码。首先，最好使用它来表示网格，而不是UITableView。它干净多了 接下来，在您的特定情况下，因为您试图在一行中显示4个网格，所以需要在UItableView的cellForRow委托中使用modulo%运算符。同时将uitableview委托中的项目数调整为totalitems/4。我敢打赌还有几件事我忘了提
我强烈建议您花点时间迁移到UICollectionView它的cleaner…首先，您最好使用它来表示网格，而不是UITableView。它干净多了 接下来，在您的特定情况下，因为您试图在一行中显示4个网格，所以需要在UItableView的cellForRow委托中使用modulo%运算符。同时将uitableview委托中的项目数调整为totalitems/4。我敢打赌还有几件事我忘了提

Saad你能把你写的代码放进去吗。这样我们可以试着纠正错误。你能把你写的代码放进去吗。因此，我们可以尝试纠正错误。嗨，我想知道复制粘贴所有代码在这里有什么意义。包括你的逻辑和一切。这实际上会让用户感到困惑。我同意提供你所拥有的一切总是更好的。所以用户可以决定带什么和不带什么。但我认为@arizah已经成功地展示了表格视图。他实际上是在与我的逻辑作斗争。当时如果你提供这么长的代码。我不明白这一点。我很感激你也给了他截图，这将有助于他。但是我不同意你把所有的代码都贴在CellforRow的索引路径上，从宽度计算文本的重量，点击按钮，gridImageRect，descriptionOfImage等等。但是他到底想要什么，伙计？？？@ParasJoshi他想要什么我们需要问他。但我他妈的肯定他不想从宽度计算文本的重量，btnTemp\u点击，gridImageRect，DescriptionofImages：p@Rushi哦，好吧，伙计，如果我明白阿里什到底想要什么，那么我就把那个帖子删除了。。谢谢嗨，我想知道在这里复制粘贴你所有的代码有什么意义。包括你的逻辑和一切。这实际上会让用户感到困惑。我同意提供你所拥有的一切总是更好的。所以用户可以决定带什么和不带什么。但我认为@arizah已经成功地展示了表格视图。他实际上是在与我的逻辑作斗争。当时如果你提供这么长的代码。我不明白这一点。我很感激你也给了他截图，这将有助于他。但是我不同意你把所有的代码都贴在CellforRow的索引路径上，从宽度计算文本的重量，点击按钮，gridImageRect，descriptionOfImage等等。但是他到底想要什么，伙计？？？@ParasJoshi他想要什么我们需要问他。但我他妈的肯定他不想从宽度计算文本的重量，btnTemp\u点击，gridImageRect，DescriptionofImages：p@Rushi哦，好吧，伙计，如果我明白阿里什到底想要什么，那么我就离开 我喜欢那个邮递员。。谢谢
