搜索自定义UITableCell的项目并使用Swift 4进行筛选

swift iphone ios

我正在尝试在UITableViewController中实现搜索功能。所以我在UITableView中的单元格顶部添加了一个搜索控制器。

我做过这个 UISearchBarDelegate 用我的TableViewController。

以下是我过滤搜索文本的代码:

// This method updates filteredData based on the text in the Search Box
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
    // When there is no text, filteredData is the same as the original data
    // When user has entered text into the search box
    // Use the filter method to iterate over all items in the data array
    // For each item, return true if the item should be included and false if the
    // item should NOT be included
    filteredData = searchText.isEmpty ? OrderDetailsTabBarViewController.orderDetailsList : OrderDetailsTabBarViewController.orderDetailsList.filter { (item: OrderBookedSetterGetter) -> Bool in
        // If dataItem matches the searchText, return true to include it
        return item.BookedOrderId(of: searchText, options: .caseInsensitive, range: nil, locale: nil) != nil
    }

    tableView.reloadData()
}

但是,它显示了错误 无法调用非函数类型“Int”的值 在 返回项目.BookedOrderId(共:searchText,选项:。不区分大小写,范围:nil,区域设置:nil)!=无

预订订单 是Int

谁能帮我一下吗。我困在这里什么也找不到。

我就是这么做的,而且很管用!

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        // When there is no text, filteredData is the same as the original data
        // When user has entered text into the search box
        // Use the filter method to iterate over all items in the data array
        // For each item, return true if the item should be included and false if the
        // item should NOT be included


            self.searchBar.showsCancelButton = true

            self.copied_order_Canceled_DetailList = []
            for item in self.order_Canceled_DetailList {
            if String(item.orderId).localizedCaseInsensitiveContains(searchText) != false{
               self.copied_order_Canceled_DetailList.append(item))
            } else {

                }
            }

            self.tableview.reloadData()
            if searchText == "" {
                self.copied_order_Canceled_DetailList = self.order_Canceled_DetailList
                self.tableview.reloadData()
            }
        }

这应该管用。

range(of... Int 到 String

filteredData = searchText.isEmpty ? OrderDetailsTabBarViewController.orderDetailsList : OrderDetailsTabBarViewController.orderDetailsList.filter { (item: OrderBookedSetterGetter) -> Bool in
    // If dataItem matches the searchText, return true to include it
    let stringOrderId = String(item.BookedOrderId)
    return stringOrderId.range(of: searchText, options: .caseInsensitive) != nil
}
