删除给出错误和崩溃应用程序的单元格

Deleting cell giving error and crashing app

我需要一些帮助来弄清楚为什么会出现此错误。我目前有一个附加结构的视图控制器(我们称之为 ADDPersonVC)。该结构如下所示:

import UIKit

struct Person {
    var Name: String?
    var PostNumber: String?
    var StoryNumber: String?
    var Compensation: String?
    var ProfileImageUrl: String?
}

我在 ADDPersonVC 中有一个按钮,用于在第二个视图控制器(我们称之为 considerationsTestVC)的 tableViewCell 中附加标签。行数由:

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

附加结构的 addPersonButton 代码如下所示:

@IBAction func addButtonTapped(_ sender: Any) {
    
    ConsiderationsTestViewController.people.append(Person(Name: "\(nameTextField.text!)", PostNumber: "\(gridTextField.text!)", StoryNumber: "\(storyTextField.text!)", Compensation: "\(compensationTextField.text!)", ProfileImageUrl: "\(userProfileImageUrlLabel.text!)"))
    
    self.navigationController?.popViewController(animated: true)
    
    DispatchQueue.main.async {
       NotificationCenter.default.post(name: NSNotification.Name(rawValue: "load"), object: nil)
            }
}

在 ConsiderationsTestViewController 中,我有一个名为 people 的静态变量,如下所示:

static var people: [Person] = []

然后我可以使用以下代码在 ConsiderationsTestViewContoller 中附加标签:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let cell = tableView.dequeueReusableCell(withIdentifier: AddPersonCell, for: indexPath) as! ConsiderationsCell
    
    let numberOfPeopleCells = ConsiderationsTestViewController.people[indexPath.row]
    
    
    cell.nameLabelC.text = numberOfPeopleCells.Name
    cell.feedLabelC.text = numberOfPeopleCells.PostNumber
    cell.storyLabelC.text = numberOfPeopleCells.StoryNumber
    cell.compensationLabelC.text = numberOfPeopleCells.Compensation
    cell.userImage.loadImageUsingCacheWithUrlString(urlString: numberOfPeopleCells.ProfileImageUrl!)
    
    cell.userImage.layer.cornerRadius = 25
    
    cell.nameLabelC.numberOfLines = 0
    
    return cell
}

当我去删除单元格时,我使用的代码是:

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
    if (editingStyle == .delete) {
        
        ConsiderationsTestViewController.people.remove(at: indexPath.row)
        // handle delete (by removing the data from your array and updating the tableview)
    }
}

当我在单元格上滑动并单击删除时出现错误:

 "Thread 1: Fatal error: Index out of range"

行:

ConsiderationsTestViewController.people.remove(at: indexPath.row)

我整个星期都在研究这个问题,希望能得到一些帮助来解决这个问题。我很高兴我能够让结构充当数组并正确显示正确的信息。我在将它上传到 Firebase - realtimeDatabase 时也遇到了问题,但这是我弄清楚之后的问题。

感谢所有帮助。

当我 运行 在删除函数上设置断点并获取值时 returns:

我也试过这个:

 po ConsiderationsTestViewController.people[indexPath.row]

我收到了以下信息:

 Fatal error: Index out of range: file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-1103.2.25.13/swift/stdlib/public/core/ContiguousArrayBuffer.swift, line 444

我需要在删除函数中添加以下代码

tableView.deleteRows(at: [indexPath], with: .fade)
