Question

我有一个表视图，

我有一个数据库使用Firebase获取一些数据：标题，标题，图像。

标题和标题显示完美，并从Firebase中获取。但是，没有图像出现。 ..

任何帮助都会令人惊叹:) :)

我的View控制器的代码如下：

<div class="myTabs">
   <ul class="tabs" data-tab data-options="deep_linking:true">
        <li><a data-toggle="tab" href="#One">Tab 1</a></li>
        <li><a data-toggle="tab" href="#Two">Tab 2</a></li>
   </ul>
</div>
<div class="tabContent">
   <div id="One">This is the content in div one on Tab 1</div>
   <div id="AnotherOne">This is the content is second div on Tab 1</div>
</div>

要调用图像，我有以下内容：cell.swift

import SwiftKeychainWrapper
import SwiftyJSON

var posts = [Post]()
var selectedIndexPath: Int = 0

class FeedVC: UIViewController, UITableViewDataSource, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UITableViewDelegate {

@IBOutlet weak var feedTableView: UITableView!

private var readPosts: ObserveTask?

@IBOutlet weak var imageView: UIImageView!

override func viewDidLoad() {
    super.viewDidLoad()

    feedTableView.dataSource = self
    feedTableView.delegate = self

    readPosts = Post.observeList(from: Post.parentReference.queryOrdered(byChild: Post.PROPERTY_CREATED)) {
        observedPosts in

        posts = observedPosts.reversed()
        self.feedTableView.reloadData()
    }
}

func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}

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

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

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

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

    let messageImageView = cell.viewWithTag(1) as! UIImageView
    let titleLabel = cell.viewWithTag(2) as! UILabel
    let captionText = cell.viewWithTag(3) as! UILabel


    titleLabel.text = posts[indexPath.row].title
    titleLabel.numberOfLines = 0

    captionText.text = posts[indexPath.row].caption
    captionText.numberOfLines = 0


    return cell

}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    selectedIndexPath = indexPath.row
    self.performSegue(withIdentifier: "push", sender: self)
    self.feedTableView.reloadData()
}
}

我已使用以下内容更新了我的feed.swift：

 import UIKit
 import FirebaseStorage


 class MessageCell: UITableViewCell
 {
 // @IBOutlet weak var profileImageView: UIImageView!
 // @IBOutlet weak var likeButton: UIButton!

 @IBOutlet weak var messageImageView: UIImageView!
 @IBOutlet weak var messageTextView: UITextView!
 @IBOutlet weak var titleTextView: UITextView!
 @IBOutlet weak var linkbutton: UIButton!

 // @IBOutlet weak var likeLabel: UILabel!

private var post: Post!

func configureCell(tableView: UITableView, post: Post)
{
    self.post = post

    // Basic info
  //        self.messageImageView.image = postPic

   messageImageView.image = post.postPic
   titleTextView.text = post.title
    messageTextView.text = post.caption


    // Post user
    User.get(id: post.creatorId)
    {
        postCreator in 




    // Image
    Storage.getImage(with: post.imageUrl)
    {
        postPic in

        self.messageImageView.image = postPic
        // Row height changes so table needs to be reset
        tableView.beginUpdates()
        tableView.endUpdates()
    }
}

使用SDWebImage - 但我仍然没有显示任何图像：（

Answer 1

您没有看到任何图片，因为您从未设置过它们。您需要在{ _id: someid, createdAt: new Date(), message: somemessage, eadd: eadd }

内拨打configureCell

图像不显示在firebase的表格单元格中
