在uiTableView的节中重复数据

sections uitableview swift arrays

Jake2Finn · 技术社区 · 6 年前

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。除第2节中重复的项目外,一切都很好:

但是,我想这样做:

我的代码如下:

Swift 4

serverData类型的结构结构服务器数据{ var structhosts:字符串 var structStatusImagesMain:字符串 var structServerStatusMin:字符串 } < /代码>
填充单元格和节的变量:

//data filled in my array“section”and in my array“myserverinfo”of type serverdata 设区段=[“区段1”,“区段2”] 让我的服务器信息=[ serverdata(structhosts:“www.google.com”,structstatusmagesmain:“错误”,structserverstatusmain:“错误”), serverdata(structhosts:“www.amazon.com”,structstatusmagesmain:“错误”,structserverstatusmain:“错误”), serverdata(structhosts:“www.ebay.com”,structstatusmagesmain:“错误”,structserverstatusmain:“错误”), 服务器数据(structhosts:“www.apple.comt”,structstatusmagesmain:“错误”,structserverstatusmain:“错误”)。 ] < /代码> 这些是表配置: //表函数 func tableview(u tableview:uitableview,titleforheaderinsection部分:int)->字符串?{ 返回段[段] } func numberofsections(在TableView:uiTableView中)->int{ 返回sections.count } func tableview(u tableview:uitableview,numberofrowspeagon部分:int)->int{ 返回2 } func tableview(u tableview:uitableview,cellforrowat indexpath:indexpath)->uitableviewcell{ 让cell=serverstatusable.dequeuerusablecell(带标识符:“serverstatuscell”,用于:indexpath) 让lblDescription:uiLabel=cell.contentView.viewWithTag(6)为!乌拉贝尔让lblserverstatus:uilabel=cell.contentview.viewwithtag(8)as!乌拉贝尔将imgserver:uiImageView=cell.contentView.viewWithTag(7)设为!UIIVIEVIEW 如果我的服务器信息是空的{ 打印(“myserverinfo为空:”,myserverinfo) }否则{ lblDescribtion.text=myServerInfo[indexPath.row].structhosts imgserver.image=uiimage(名为:myserverinfo[indexpath.row].structstatusImagesMain) lblserverstatus.text=myServerInfo[indexPath.row].structServerStatusMain } 返回单元 } < /代码> 但是,我想这样做: 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 } 填充单元格和节的变量: // 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 }

这三行:

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

有两个部分,每个部分在表中有两行。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,表示总共4个,与数组的长度匹配。

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

不过,有一个警告:如果希望每个部分的行数不同,那么构造数据的方式就意味着很多问题。

1)首先必须为节数据创建结构

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

}

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

2)然后我们为每个章节标题填充数据

    // 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)配制台视图

// 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
}
