swift - 当searcBar有文本时，我无法重新加载tableView

Question

当我的searchBar处于活动状态并有文本时，我可以删除单元格，但是当其删除时，该单元格保持空白，我的意思是不会重新加载吗？这是我的deleteAction；

        if self.searchController.isActive && self.searchController.searchBar.text != "" {

            context.delete(filteredArray[indexPath.row])
            tableView.reloadData()
            self.appDelegate.saveContext()
            do { people = try context.fetch(Person.fetchRequest()} catch { print("Fetching Failed !!")}

        } else {

            context.delete(people[indexPath.row])
            self.appDelegate.saveContext()
            do { people = try context.fetch(Person.fetchRequest())} catch { print("Fetching Failed !!")}
            tableView.reloadData()

        }

并为cellForRowAt。编写代码。

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell") as UITableViewCell!

        let person = people[indexPath.row]

        if searchController.isActive && searchController.searchBar.text != "" {
            cell?.textLabel?.text = filteredArray[indexPath.row].name

            if filteredArray[indexPath.row].isChecked {
                cell?.accessoryType = .checkmark
            } else {
                cell?.accessoryType = .none
            }

        } else {
            cell?.textLabel?.text = person.name

                if person.isChecked {
                    cell?.accessoryType = .checkmark
                } else {
                    cell?.accessoryType = .none
                }

        }

        cell?.backgroundColor = UIColor.clear // loading color

        return cell!
    }

这是屏幕截图；

原因是因为您要从name中提取filteredArray：

if searchController.isActive && searchController.searchBar.text != "" {
    cell?.textLabel?.text = filteredArray[indexPath.row].name // this line

但是，您只更新了 people数组：

if self.searchController.isActive && self.searchController.searchBar.text != "" {
    context.delete(filteredArray[indexPath.row])
    self.appDelegate.saveContext()

    // This line below
    do { people = try context.fetch(Person.fetchRequest()} catch { print("Fetching Failed !!")}
    // Please also update your filteredArray here
    filteredArray = ... 

    // And don't forget to reload after date is updated. 
    tableView.reloadData()
} else {
...

更新 filteredArray后，它应该可以工作。
