从.xib创建的自定义UITableViewCell不显示

问题描述

我迷路了.我进行了搜索，找不到我的自定义单元格未显示的原因.

I'm lost. I searched and searched and cannot find the reason why my custom cell isn't displayed.

//  ProfileCell.swift:

import UIKit
import QuartzCore

class ProfileCell: UITableViewCell {

    @IBOutlet weak var profileNameLabel:    UILabel!
    @IBOutlet weak var profilePictureView:  UIImageView!
}

第二个默认TableViewCell正常显示.我在Interface Builder中没有缺少约束或任何错误.在ProfileCell.xib身份选项卡中选择ProfileCell作为自定义类.

The second default TableViewCell is displayed normally. I have no missing constraints in Interface Builder or any Errors. ProfileCell is selected in the ProfileCell.xib identity tab as the custom class.

//  MoreTableViewControllerIB.swift

import UIKit

class MoreTableViewControllerIB: UITableViewController {

override func viewDidLoad() {
    super.viewDidLoad()
}

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

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        //  this cell is missing
        if indexPath.row == 0 {

            tableView.register(UINib(nibName: "ProfileCell", bundle: nil), forCellReuseIdentifier: "ProfileCell")
            let cell = tableView.dequeueReusableCell(withIdentifier: "ProfileCell", for: indexPath) as! ProfileCell
            cell.profileCommentLabel.text = "Test Comment Label"
            cell.profilePictureView.image = UIImage(named:"profile_picture_test")
            return cell

        // this cell is displayed perfectly
        }else if indexPath.row == 1 {

            let cell = tableView.dequeueReusableCell(withIdentifier: "statisticsCell") ?? UITableViewCell(style: .default, reuseIdentifier: "statisticsCell")
            cell.accessoryType = UITableViewCellAccessoryType.disclosureIndicator
            cell.textLabel?.text = "Statistics"
            cell.imageView.image = UIImage(named:"statistics")
            return cell

        // has to return a cell in every scenario
        }else{
            let cell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as UITableViewCell
            return cell
        }
    }
}

这是我所得到的屏幕截图.

推荐答案

tableView.register(UINib(nibName: "ProfileCell", bundle: nil), forCellReuseIdentifier: "ProfileCell")

将此行添加到viewDidLoad或viewWillApppear

add this line in viewDidLoad or viewWillApppear
