arrays - 填充 UITableView 节标题标题，因为节 == 2？

Question

我有一个来自名为 firstData 的服务器的响应数组，它有 12 个元素。里面有一堆字典，我做了一些过滤器将其分成 3 个不同的数组，如下所示:

    //filter to get all type Switch into one array.
    self.dataSwitchOnly = self.firstData.filter {
                    $0.type.rawValue == "Switch"
                }// 7 elements

//looping dataSwitchOnly to get all shop type.
                for i in 0..<self.dataSwitchOnly.count {
                    if (self.dataSwitchOnly[i].search_key == "shop_type" || self.dataSwitchOnly[i].search_key == "is_certified"){
                        self.shopTypeArr.append(self.dataSwitchOnly[i])
                    }
                }// 2 elements

//filter original data to get all elements are not have type Switch.
                self.dataAfterFilterSwitch = self.firstData.filter {
                    $0.type.rawValue != "Switch"
                }//5 elements

我的 UITableView numberOfSections 像这样:

//return filtered array which is not type `Switch` then + 2 more static section 0 and 1.
    return dataAfterFilterSwitch.count + 2

并且因为 shopTypeArr 和 dataSwitchOnly 没有相同的名称。因此，我必须对它们的标题标题进行硬编码，第 0 部分是“快速过滤器”，第 1 部分是“商店类型”。

现在我想显示从第 2 部分到 tableView 末尾的 dataAfterFilterSwitch。但是，当我设置 dataAfterFilterSwitch[section] 来获取属性 name 时，我收到错误 index out of range。也许我的问题让你们很困惑，但我可以提供更多代码来解决这个问题。

我的代码逻辑哪里有问题？

我的viewForHeaderInSection:

let itemFilter = self.dataAfterFilterSwitch[section-2]
//        header.isCollapse =  collapse[section]
//        header.delegate = self
        if section == 0 {
            let data = SectionHeaderModel(sectionTitle: "Quick Filter".uppercased())
            if header.isCollapse == 0 {
                header.sectionComponents?.bind(data: data, state: .collapse, imageState: ImageDataType.image(UIImage(named: "icon-24-chevron-bottom")!), target: self, selector:nil)
            }else {
                header.sectionComponents?.bind(data: data, state: .collapse, imageState: ImageDataType.image(UIImage(named: "icon-24-chevron-top")!), target: self, selector:nil)
            }
            return header
        }else if section == 1 {
            let data = SectionHeaderModel(sectionTitle: "Shop Type".uppercased())
            if header.isCollapse == 0 {
                header.sectionComponents?.bind(data: data, state: .collapse, imageState: ImageDataType.image(UIImage(named: "icon-24-chevron-bottom")!), target: self, selector:nil)
            }else {
                header.sectionComponents?.bind(data: data, state: .collapse, imageState: ImageDataType.image(UIImage(named: "icon-24-chevron-top")!), target: self, selector:nil)
            }
            return header
        }else {
            let data = SectionHeaderModel(sectionTitle:(itemFilter.name)!.uppercased())
            if header.isCollapse == 0 {
                header.sectionComponents?.bind(data: data, state: .collapse, imageState: SImageDataType.image(UIImage(named: "icon-24-chevron-bottom")!), target: self, selector:nil)
            }else {
                header.sectionComponents?.bind(data: data, state: .collapse, imageState: ImageDataType.image(UIImage(named: "icon-24-chevron-top")!), target: self, selector:nil)
            }
            return header
        }

由于您在 tableView 中添加了两个硬代码部分，并且您必须在这些部分之后显示数组的数据。您必须像这样从数组中检索数据 dataAfterFilterSwitch[section - 2]
