ios - UITableView 中的自定义单元格标签未填充

Question

在我的 Storyboard上有一个带有两个 View Controller 的选项卡栏 Controller 。第一个 View Controller 有一个 UITableView，第二个 View Controller 用于收集数据，这些数据将以表格 View 格式显示在第一个 View Controller 上。

为此，我创建了四个 swift 文件:

1. TARISKTREATMENT.swift - 包含链接到第一个 View Controller (带有 UITableView 的 View Controller )的类 TARISKTREATMENT

2. TAADDRISKTREATMENT.swift - 包含链接到第二个 View Controller 的类 TAADDRISKTREATMENT。

3. TREATMENTS.swift - 用于收集在第二个 View Controller 上输入的数据的结构。

4. CUSTOMTREATMENTCELL.swift - 自定义单元格的 UITableViewCell 类。

第二个 View Controller 完美地收集了来自用户的数据，当我运行打印命令时，我可以看到数据实际上在结构中。

出于某种原因，TARISKTREATMENT.swift 中的代码没有填充自定义单元格。

我在这里做错了什么？

代码:TARISKTREATMENT.swift(带有 UITableView 的 View Controller 1 - 那个不工作的...)

import UIKit

class TARISKTREATMENT: UIViewController, UITableViewDataSource, UITableViewDelegate {

    @IBOutlet weak var TreatmentsTableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        TreatmentsTableView.dataSource = self
        TreatmentsTableView.delegate = self
        TreatmentsTableView.reloadData()

    }//END - viewDidLoad

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

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let IndividualCell = TreatmentsTableView.dequeueReusableCellWithIdentifier("TreatmentCell", forIndexPath: indexPath) as! CUSTOMTREATMENTCELL

        IndividualCell.outletLabel_TreatmentPackageName.text = TreatmentsManager.newTreatments[indexPath.row].varTreatmentPackageName

        IndividualCell.outletLabel_TreatmentDescription.text = TreatmentsManager.newTreatments[indexPath.row].varTreatmentPackageDetail

        IndividualCell.outletLabel_TreatmentResponsiblePerson.text = TreatmentsManager.newTreatments[indexPath.row].varTreatmentResponsiblePerson

        IndividualCell.outletLabel_TreatmentDTGCompleted.text = String(TreatmentsManager.newTreatments[indexPath.row].varTreatmentDTGCompleted)

        let varSelectPriorityPic = TreatmentsManager.newTreatments[indexPath.row].varTreatmentPriority

        switch varSelectPriorityPic {   
        case "HIGH":
            IndividualCell.outletImage_TreatmentPriority.image = imageTreatmentPriorityHigh
        case "MEDIUM":
            IndividualCell.outletImage_TreatmentPriority.image = imageTreatmentPriorityMedium
        case "LOW":
            IndividualCell.outletImage_TreatmentPriority.image = imageTreatmentPriorityLow
        default:
            break
        }
        return IndividualCell
    }

    func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){
        if (editingStyle == UITableViewCellEditingStyle.Delete){

            TreatmentsManager.newTreatments.removeAtIndex(indexPath.row)
            TreatmentsTableView.reloadData()
        }
    }
}

代码:TREATMENTS.swift

import UIKit

var TreatmentsManager: classTreatmentsManager = classTreatmentsManager()

struct structTreatment {
    var varTreatmentPackageName : String
    var varTreatmentPackageDetail : String
    var varTreatmentResponsiblePerson : String
    var varTreatmentPriority : String
    var varTreatmentDTGCompleted : NSDate
}

class classTreatmentsManager: NSObject {

    var newTreatments = [structTreatment]()

    func funcAddTreatment(varTreatmentPackageName: String, varTreatmentPackageDetail: String, varTreatmentResponsiblePerson: String, varTreatmentPriority: String, varTreatmentDTGCompleted: NSDate){

        newTreatments.append(structTreatment(varTreatmentPackageName: varTreatmentPackageName, varTreatmentPackageDetail: varTreatmentPackageDetail, varTreatmentResponsiblePerson: varTreatmentResponsiblePerson, varTreatmentPriority: varTreatmentPriority, varTreatmentDTGCompleted: varTreatmentDTGCompleted))
    }
}

代码:CUSTOMTREATMENTCELL.swift

import UIKit

class CUSTOMTREATMENTCELL: UITableViewCell {

    @IBOutlet weak var outletImage_TreatmentPriority: UIImageView!

    @IBOutlet weak var outletLabel_TreatmentPackageName: UILabel!

    @IBOutlet weak var outletLabel_TreatmentDescription: UILabel!

    @IBOutlet weak var outletLabel_TreatmentResponsiblePerson: UILabel!

    @IBOutlet weak var outletLabel_TreatmentDTGCompleted: UILabel!

    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }
}

感谢您的帮助 - 谢谢!

Answer 1

您的代码中的一切都很好。您错过的是重新加载数据:

 override func viewWillAppear() {
    super.viewWillAppear()
    TreatmentsTableView.reloadData()
}
