Question

我有一个联系人应用程序，我有一个视图，用户可以单击该视图查看用户的“详细”信息。在此详细视图中，它仅显示具有值的字段，并隐藏其余字段。当用户单击“编辑”时，它将显示允许用户编辑的所有字段。

让我展示一下这个

的一些屏幕

Detailed View with hidden rows

Edit View

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

这是我的实际问题 我提出this post我问的是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”。

我需要找出一种显示和表示动态生成的电子邮件/电话号码的方法。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）。我将所有这些存储在NSDurray的NSArray中（key = label，value = email / phone），每个联系人将有两个NSArray。

我只需要在如何动态和静态的同时获得一些帮助？我不想失去隐藏细胞的功能。

我将粘贴处理表视图的类。

查看代码后

。 StaticDataTableViewController使用tableview根据自己的“OriginalRow”类显示您希望它显示的单元格。

它们保存在属性“rows”下的“OriginalSection”类中的Mutable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

原始表是您的表应包含的主要定义，并保存在名为“originalTable”的属性下的“StaticDataTableViewController”

确定要显示哪些单元格以及要隐藏哪些单元格的所有业务都在“ - [OriginalTable prepareUpdates]”中完成，它遍历各个部分和每行内部以确定要显示的内容和隐藏的内容。

“ - [OriginalTable sections]”数组和“ - [OriginalSection rows]”数组分别继续包含所有节和行，无论其可见性或隐身性如何，因此如果您编辑这些数组并调用“ - [StaticDataTableViewController reloadData] “你将获得你正在寻找的行动。

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

当你将OriginalRow，OriginalSection和OriginalTable的“@interface”移动到标题时，你就是那里的大部分。

最后要做的是将属性从StaticDataTableViewController的私有类别移动到公共接口。

@interface StaticDataTableViewController ()

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

@end

取标记的行并将其移动到公共接口的标题中，使其成为公共属性

@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Sections和Rows。

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

这样可以帮助你顺利完成。

我应该重新设计实现还是可以动态地将单元格添加到静态表视图控制器
