【中文标题】单击按钮时将单元格动态添加到 UItableview【英文标题】：Adding cells dynamically to UItableview when Button clicks 【发布时间】：2013-03-11 06:37:09 【问题描述】：我有 2 个 UITextField 和一个按钮，当我在填充这些按钮后单击按钮时，我必须在表格视图单元格中以相同格式获取 UItextfields 和按钮，当我填充这些并单击按钮时，必须将相同的文本字段添加到下一个单元格，保持上述内容单元格相同，并且文本字段中的数据也不会被删除
我是这个编程的新手，我不知道如何在单击按钮时向单元格添加视图 帮我解决这个问题。

【问题讨论】：
尝试在自定义的uitableviewcell上搜索google.co.in/… 当 addbutton 被点击时，我想向 tableviewcell 添加另一个视图，这样我如何使用标签动态添加单元格 您可以添加您的视图并将其隐藏在开头，当单击按钮时重新加载您的表格并根据条件设置隐藏为 false。 查看我的编辑问题。我想将这些功能添加到表格视图中，我该怎么做 【参考方案1】：您可以从here下载示例应用程序

编辑：
您只需重新加载 ([tablename reloadData];) -(IBAction)btnaddbusiness:(UIButton*)sender 中的表格。
添加你正在做的视图应该在rowForIndexPath:。
您可以做的是在您的函数中将一个变量 boolean 设置为 TRUE 并 reload 您的表，然后在 rowForIndexPath 中检查如果该变量为 true，则将您的视图的 hidden 属性设置为 False，反之亦然。
【讨论】：
我怎样才能将它添加到单元格中的各个行以用于索引路径处的行 您可以在 rowForIndexPath 中创建 txtprovName2 并将其添加到您的行中，例如[cell.contentView addSubview: txtprovName2];以上是关于单击按钮时将单元格动态添加到 UItableview的主要内容，如果未能解决你的问题，请参考以下文章
