Question

我只是从一本书中学习PHP，我正在做一个练习，目的是创建一个成绩计算器。我试图让这个等级在形式下回响，我遇到了麻烦。

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


        if currentSearch == "new" {
        self.PersonalSearchesList = PersonalSearchesList.sorted{ $0.users < $1.users }

        } else if currentSearch == "top" {

          self.PersonalSearchesList = self.PersonalSearchesList.sorted{ $0.latestUser < $1.latestUser }

        }

您的表单需要提交按钮和操作属性。你的变量也写得不正确。
