Question

我使用的是自定义UICollectionView，它有许多单元格，每个单元格底部附近都有一个按钮。我想要做的是在单击给定单元格按钮时显示数字表格列表。表格列表将是一个简单的数字列表[1-n]，其中n在单元格的indexPath（即节和行）上有所不同。

我想弄清楚的是：

1）如果单击给定单元格的按钮，如何打开uitableview？ 2）我打开的uitableview是否必须占用整个屏幕？

基本上我不希望它占用整个屏幕（因为我被锁定在横向模式下，这看起来很奇怪）所以我想知道如何控制tableView的宽度和高度？

对不起iOS问题抱歉，感谢您的帮助！

Answer 1

UITableView不需要占用整个屏幕。您可以设置tableview的框架，并根据您是否要显示它来设置hidden = YES或=NO。

Answer 2

您可以使用KGModal。您可以使用UITableViewController向您显示数据，然后使用

添加您的tableview

- (void)showWithContentViewController:(UIViewController *)contentViewController andAnimated:(BOOL)animated;

也不用担心迎新，KGModal足够聪明，可以为你处理:)

希望这会奏效。
