数组数据在 swift 4 的表视图中重复

Question

这些是一些变量，我想在表格视图或集合视图中显示哪些数据。

   let inr = ["200.0", "1200.0", "500.0", "2000.0", "2000.0", "2000.0", "2000.0", "2000.0", "3000.0", "5000.0", "1000.0", "100000.0", "100000.0"]
let reqtime = ["2018-04-11 13:54:46", "2018-04-09 16:31:42", "2018-04-09 12:26:32", "2018-04-09 12:19:40", "2018-04-09 12:19:35", "2018-04-09 12:19:23", "2018-04-09 12:09:05", "2018-04-09 12:08:25", "2018-04-09 11:38:15", "2018-04-09 11:07:59", "2018-04-09 11:03:58", "2018-04-09 10:54:55", "2018-04-09 10:45:47"]
let status = ["Request Approve", "Request Pending", "Request Pending", "Request Pending", "Request Pending", "Request Approve", "Request Pending", "Request Pending", "Request Pending", "Request Pending", "Request Pending", "Request Pending", "Request Approve"]

这是我的表格视图委托功能代码：

func numberOfSections(in tableView: UITableView) -> Int {
    //print("inrvalue sec\(self.inrValues.count)")
    return inr.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
    //print("section p\(self.requestTimeValue[section])")
    return reqtime[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return 1
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 44.0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableViewOutlet.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! DepositHistoryTableViewCell


    let inrval = Double(inr[indexPath.section])
    cell.lblINR.text = String(inrval)

    cell.lblStatus.text = status[indexPath.section]


    return cell
}

数据显示如下图： table view data

问题 1. 想要显示这样的数据...

Section: reqtime(row[0]) 
inr(row[0])
status(row[0]),
Section: reqtime(row[1])
inr(row[1]) 
status(row[1])
Section: reqtime(row[2])
inr(row[2])
status(row[2])

等等。

问题 2：有没有其他方法可以更好地显示这些数据，例如：any other way to data like this in swift

更改我的代码后，数据如下图所示：this is how data shown after numberofRowinSection return 1

Answer 1

在这里，inr、reqtime 和 status 中的项目数量相同，因此对于每个 inr 项目，您将只有一个 reqtime 和 single 状态：

将您的numberOfRowsInSection 更新为：

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 1
}

注意：目前你在这个方法中返回reqtime[section] (String)也是不对的，因为这个函数只能有一个Int返回值。

将 UITableView 的委托和数据源方法更新为：

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

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

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // Here you have same no of items in inr, reqtime and status so for each inr item you will only have a single reqtime and single status
    return 1
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 60.0
}

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

    let inrval = Double(inr[indexPath.section])
    cell.lblINR.text = String(format: "%.2f",inrval)
    cell.lblStatus.text = status[indexPath.section]

    return cell
}

更新： // 如果你想像水平表一样显示数据

let inr = ["200.0", "1200.0", "500.0", "2000.0", "2000.0", "2000.0", "2000.0", "2000.0", "3000.0", "5000.0", "1000.0", "100000.0", "100000.0"]
let reqtime = ["2018-04-11 13:54:46", "2018-04-09 16:31:42", "2018-04-09 12:26:32", "2018-04-09 12:19:40", "2018-04-09 12:19:35", "2018-04-09 12:19:23", "2018-04-09 12:09:05", "2018-04-09 12:08:25", "2018-04-09 11:38:15", "2018-04-09 11:07:59", "2018-04-09 11:03:58", "2018-04-09 10:54:55", "2018-04-09 10:45:47"]
let status = ["Approve", "Pending", "Pending", "Pending", "Pending", "Approve", "Pending", "Pending", "Pending", "Pending", "Pending", "Pending", "Approve"]


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

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 40.0
}

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

    cell.lblRequestTime.text = reqtime[indexPath.row]
    let inrval = Double(inr[indexPath.row])
    cell.lblINR.text = String(format: "%.2f",inrval!)
    cell.lblStatus.text = status[indexPath.row]

    return cell
}
