我使用xib在我的表视图单元格上拥有ui集合视图。 我想将我从API获得的数据传递到表视图单元格内的ui集合视图
这是我的代码
模型
class MessageTextType {
var messageType: String = ""
var messageFromMe: String = ""
var date: String = ""
var type: String = ""
var text: String = ""
var image: String = ""
var imagePreview: String = ""
var time: String = ""
var speech: String = ""
var resolvequery: String = ""
var columnCarousel: String = ""
}

答案 0 :(得分：0)
您必须以cellrowAt方法传递数据。
更新您的代码：
let cell : MessageCarousel! = tableView.dequeueReusableCell( withIdentifier: "MessageCarousel") as? MessageCarousel
** cell.yourDataArray = chatinfo.arrayColumns **
cell.carouselImage.reloadData()
return cel
// yourInputArray is array that contain collectionview data
class MessageCarousel: UITableViewCell {
var yourDataArray = NSMutableArray() // or any other array.
//.... your code
}
您必须更新模型MessageTextType，在columns中添加MessageTextType变量数组
class MessageTextType {
var arrayColumns : [Column]!
//... your rest code
}
class Column {
var thumbnailImageUrl : String!
var title : String!
public class func modelsFromDictionaryArray(array:NSArray) -> [Column]
{
var models:[Column] = []
for item in array
{
models.append(Column(dictionary: item as! NSDictionary)!)
}
return models
}
required public init?(dictionary: NSDictionary) {
thumbnailImageUrl = dictionary["thumbnailImageUrl"] as? String ?? ""
title = dictionary["title"] as? String ?? ""
}
init() {
}
}
在API响应中添加以下代码：
let columns = Column.modelsFromDictionaryArray(array:subJson["columns"])
message.arrayColumns = columns

import UIKit
class ViewController : UIViewController {
}
extension ViewController:UITableViewDataSource,UITableViewDelegate{
// this is for your tableView
In your tableView Cell :-
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let chatinfo = messageTextArray[indexPath.item]
let cell : MessageCarousel! = tableView.dequeueReusableCell( withIdentifier: "MessageCarousel") as? MessageCarousel
if yourModelData != nil{
// reload collectionView
}
return cell
}
}
extension ViewController :UICollectionViewDataSource,UICollectionViewDelegate{
// This is for Your CollectionView
// In collection View
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
if yourModelData.count != 0{
return yourModelData.count
}
return 0
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "carouselViewID", for: indexPath as IndexPath) as! CarouselViewCell
// handle Model here
let msg = yourModelData[indexPath.row]. messageFromMe
return cell
}
}
// hope its worked for you
