UItableview 部分中的数据重复

Question

我有一个包含两个部分和四行的 UITableView。每个部分应该有两行内容。 除了这些项目在第 2 节中重复之外，一切正常：

但是，我想要这样：

我的代码如下：

斯威夫特 4

// structure for serverData type
struct serverData {
    var structHosts: String
    var structStatusImagesMain: String
    var structServerStatusMain: String
}

填充单元格和部分的变量：

// data filled in my array "section" and in my array "myServerInfo" of type serverData    
let sections = ["Section 1", "Section 2"]
let myServerInfo = [
    serverData(structHosts: "www.google.com", structStatusImagesMain: "error", structServerStatusMain: "Error "), 
    serverData(structHosts: "www.amazon.com", structStatusImagesMain: "error", structServerStatusMain: "Error "), 
    serverData(structHosts: "www.ebay.com", structStatusImagesMain: "error", structServerStatusMain: "Error "), 
    serverData(structHosts: "www.apple.comt", structStatusImagesMain: "error", structServerStatusMain: "Error ")
]

这些是表格配置：

// table functions    
    func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return sections[section]
    }

    func numberOfSections(in tableView: UITableView) -> Int {
        return sections.count
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 2
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = serverStatusTable.dequeueReusableCell(withIdentifier: "serverStatusCell", for: indexPath)

        let lblDescribtion : UILabel = cell.contentView.viewWithTag(6) as! UILabel
        let lblServerStatus : UILabel = cell.contentView.viewWithTag(8) as! UILabel
        let imgServer : UIImageView = cell.contentView.viewWithTag(7) as! UIImageView

                if myServerInfo .isEmpty {
                    print("myServerInfo is empty: ", myServerInfo)
                } else {
                    lblDescribtion.text = myServerInfo[indexPath.row].structHosts
                    imgServer.image = UIImage(named: myServerInfo[indexPath.row].structStatusImagesMain)
                    lblServerStatus.text  = myServerInfo[indexPath.row].structServerStatusMain
                }

        return cell
    }

Answer 1

这三行：

lblDescribtion.text = myServerInfo[indexPath.row].structHosts
imgServer.image = UIImage(named: myServerInfo[indexPath.row].structStatusImagesMain)
lblServerStatus.text  = myServerInfo[indexPath.row].structServerStatusMain

表格中有 2 个部分，每个部分有 2 行。它们映射到一个由 4 个元素组成的数组。所以index.section 从 0 到 1，index.row 也从 0 到 1，意味着总共 4 个，与数组的长度相匹配。

您需要正确地进行翻译：

let index = indexPath.section * 2 + indexPath.row

lblDescribtion.text = myServerInfo[index].structHosts
imgServer.image = UIImage(named: myServerInfo[index].structStatusImagesMain)
lblServerStatus.text  = myServerInfo[index].structServerStatusMain

但有一个警告：如果您希望每个部分具有不同的行数，那么构建数据的方式会带来很多麻烦。

Answer 2

1) 首先你必须为部分数据创建结构

Struct SectionData {
     Let title: String
     Let data: [serverData]

}

// structure for serverData type
struct serverData {
    var structHosts: String
    var structStatusImagesMain: String
    var structServerStatusMain: String
}

2) 然后我们为每个部分的标题填充数据

    // data filled in my array "section" and in my array "myServerInfo" of type serverData    

let myServerInfo = [SectionData]()
Let section1 = SectionData(title: "section1", data: 
    serverData(structHosts: "www.google.com", structStatusImagesMain: "error", structServerStatusMain: "Error "), 
    serverData(structHosts: "www.amazon.com", structStatusImagesMain: "error", structServerStatusMain: "Error "))

Let section2 = SectionData(title: "section2", data: 
    serverData(structHosts: "www.ebay.com", structStatusImagesMain: "error", structServerStatusMain: "Error "), 
    serverData(structHosts: "www.apple.comt", structStatusImagesMain: "error", structServerStatusMain: "Error "))

myServerInfo.append(section1)
myServerInfo.append(section2)

3)配置表视图

// table functions    
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    return myServerInfi[section].title
}

func numberOfSections(in tableView: UITableView) -> Int {
    return myServerInfo.count
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return myServerInfo[section].data.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = serverStatusTable.dequeueReusableCell(withIdentifier: "serverStatusCell", for: indexPath)

    let lblDescribtion : UILabel = cell.contentView.viewWithTag(6) as! UILabel
    let lblServerStatus : UILabel = cell.contentView.viewWithTag(8) as! UILabel
    let imgServer : UIImageView = cell.contentView.viewWithTag(7) as! UIImageView

            if myServerInfo .isEmpty {
                print("myServerInfo is empty: ", myServerInfo)
            } else {
                lblDescribtion.text = myServerInfo[indexPath.section][indexPath.row].structHosts
                imgServer.image = UIImage(named: myServerInfo[indexPath.section][indexPath.row].structStatusImagesMain)
                lblServerStatus.text  = myServerInfo[indexPath.section][indexPath.row].structServerStatusMain
            }

    return cell
}
