}
我的结构：
struct CellInfo {
var name:String = ""
var number:String = ""
var nameCode:String = ""
}
这两个视图都加载到支持分页的scrollView上。因此，加载的第一个视图是DialerView，在向右滚动时，我会看到ContactView。
我想要做的是使用namecode中的ContactView来过滤我的结果，并将其显示在DialerView中的UITable中，而无需重写所有代码。在DialerView中使用我的InputNumber UIlabel（名为addressBook）作为我的UItable（名为ContactView）的搜索参数并在{中显示已过滤的单元格的最佳方式{1}}（位于拨号器上方的表格中）
什么是DialerView？
namecode包含已保存联系人姓名的拨号程序组合（请在namecode中查看dict，这应该说清楚。）
我想要实现的目标：
John的名称代码为 - ＆gt; 5646.所以当我在ContactView上输入5/56/564/5646时，John应该显示为我可以在拨号器上方的UITableView中调用的预先保存的联系人
修改：我创建了一个名为DialerView的新课程，并将我的数据及其操作添加到课程中。 Info和DialerView都使用ContactView的对象，但如何让他们使用 SAME 对象来提供数据一致性？
目前，如果我添加了新的联系人（Info中提供的功能），则它不会在我的ContavtView上显示为搜索结果。它只读取预定义数据。
谢谢。
答案 0 :(得分：0)
你必须将dataSource存储在两个类都可以访问的地方（比如单例类/数据库/ NSUserDefault），然后只需将它取出来过滤/使用它们
在您的示例中，所有联系人都包含在ContactView课程中，您必须将name和number数组移到该课程之外，或者DialerView必须持有ContactView的实例来访问它们，最简单的方法是创建一个单例来容纳那2个数组
答案 1 :(得分：0)
您必须添加UIView类型类，并且在此类中，您必须添加表视图及其委托/数据源方法。并添加协议（创建自定义委托方法），以便在您想要添加此tableview时使用，表示contactview和declairview
