ios - 我应该重新设计这个实现还是可以动态地将单元格添加到 StaticTableViewController

Question

我有一个联系人应用程序，我有一个 View ，用户可以在其中单击以查看有关该用户的“详细”信息。在此详细 View 中，它将仅显示具有值的字段，并隐藏其余字段。当用户点击“编辑”时，它会显示所有字段以允许用户编辑。

让我展示一些这个的屏幕

我正在使用第三方 StaticDataTableViewController隐藏和显示单元格的类。

这是我的实际问题我做了 this post我在其中询问如何更动态地处理电子邮件和电话号码，而不是定义“工作电子邮件”、“家庭电子邮件”、“工作电话”、“家庭电话”。

我需要找出一种方法来显示和表示动态生成的电子邮件/电话号码。如果用户有 5 个电话号码，那么我想显示 5 个电话号码加上他们的标签(家庭、工作)。我会将所有这些存储在 NSDictionaries 的 NSArray 中(键 = 标签，值 = 电子邮件/电话)，每个联系人将有两个 NSArray。

我只需要一些帮助，了解如何同时保持动态和静态？我不想失去隐藏单元格的功能。

我将粘贴处理我的表格 View 的类。

Answer 1

查看代码后。 StaticDataTableViewController 使用 tableview 来显示您希望它根据自己的“OriginalRow”类显示的单元格。

它们保存在属性“行”下的“OriginalSection”类中的可变数组中。

原始部分保存在名为“sections”的属性下的“OriginalTable”类的可变数组中

原始表格是您对表格应包含的内容的主要定义，并保存在名为“originalTable”的属性下的“StaticDataTableViewController”中

确定要显示哪些单元格和隐藏哪些单元格的所有业务都在“-[OriginalTable prepareUpdates]”中完成，它遍历各个部分和其中的每一行以确定要显示什么和隐藏什么。

“-[OriginalTable sections]”数组和“-[OriginalSection rows]”数组分别继续包含所有部分和行，无论它们是否可见或不可见，因此如果您编辑这些数组并调用“-[StaticDataTableViewController reloadData] "您将获得您正在寻找的操作。

要完成此操作，您需要将每个类的“@interface”移至标题，以便您可以访问它。

当您将 OriginalRow、OriginalSection 和 OriginalTable 的“@interface”移动到标题时，您就完成了大部分工作。

最后要做的是将属性从 StaticDataTableViewController 的私有(private)类别移动到公共(public)接口(interface)。

@interface StaticDataTableViewController ()

@property (nonatomic, strong) OriginalTable * originalTable; // Cut this line.

@end

将标记的行移至公共(public)界面中的表头，使其成为公共(public)属性

@interface StaticDataTableViewController : UITableViewController // Paste after this line

完成这些更改后，您应该能够随意添加和删除节和行。

[[[[ThisStaticTable.originalTable sections] objectAtIndex:0] rows] 
                  insertObject:myNewOriginalRow atIndex:2];
[ThisStaticTable reloadData];

这应该会让您顺利上路。
