如何使用swift3在TableViewCell中的CollectionViewCell中动态显示服务器中的数据? [英] How to display dynamically data from Server in CollectionViewCell in TableViewCell with swift3?
问题描述
我从TableViewCell获取了json链接数据,然后从服务器检索该数据并在collectView中显示相关的TableViewCell数据。
如何在swift3中显示这些数据?请帮助我。
I got my json link data from TableViewCell , and then retrieve that data from server and display in collectionView with related TableViewCell data. How to display this data in swift3? Please, help me.
我从TableViewCell获得了url链接(mainThemeList.main_associated_url,main_name)。
I got url link (mainThemeList.main_associated_url,main_name) from TableViewCell.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let mainThemeList = mainHomeThemeTable[(indexPath as NSIndexPath).row]
let cell = tableView.dequeueReusableCell(withIdentifier: "homecell") as! HomeCategoryRowCell
DispatchQueue.main.async {
cell.categoryTitle.text = mainThemeList.main_name
cell.mainAssociatedURL.text = mainThemeList.main_associated_url
self.prefs.set(mainThemeList.main_name, forKey: "main_name")
cell.categoryTitle.font = UIFont.boldSystemFont(ofSize: 17.0)
cell.collectionView.reloadData()
}
DispatchQueue.main.async {
self.retrieveDataFromServer(associated_url: mainThemeList.main_associated_url,main_name: mainThemeList.main_name)
}
return cell
}
然后数据来自服务器的url链接数据。
And then data related url link data from Server.
private func retrieveDataFromServe(associated_url : String , main_name: String) {
SwiftLoading().showLoading()
if Reachability().isInternetAvailable() == true {
self.rest.auth(auth: prefs.value(forKey: "access_token") as! String!)
rest.get(url: StringResource().mainURL + associated_url , parma: [ "show_min": "true" ], finished: {(result : NSDictionary, status : Int) -> Void in
self.assetsTable.removeAll()
if(status == 200){
let data = result["data"] as! NSArray
if (data.count>0){
for item in 0...(data.count) - 1 {
let themes : AnyObject = data[item] as AnyObject
let created = themes["created"] as! String
let assets_id = themes["id"] as! Int
let name = themes["name"] as! String
var poster_img_url = themes["poster_image_url"] as! String
let provider_id = themes["provider_id"] as! Int
poster_img_url = StringResource().posterURL + poster_img_url
self.assetsTable.append(AssetsTableItem(main_name: main_name,created: created,assets_id: assets_id, name: name, poster_image_url: poster_img_url,provider_id: provider_id))
}
}
SwiftLoading().hideLoading()
}else{
SwiftLoading().hideLoading()
}
})
}
}
从assetsTable中的服务器数据存储中检索数据。
Retrieve data from Server data store in assetsTable.
然后在CollectionViewCell中显示assetsTable数据。
And then assetsTable data display in CollectionViewCell.
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "videoCell", for: indexPath) as! HomeVideoCell
cell.movieTitle.text = list.name
cell.imageView.image = list.image
return cell
}
我的问题是collectionViewCell数据与以前的assetsTable数据重复并且没有在CollectionView中显示正确的数据。
My problem is collectionViewCell data are duplicate with previous assetsTable data and didn't show correct data in CollectionView.
我的tableViewCell节目(动作,戏剧) label和My CollectionViewCell显示电影名称和电影图像。我从服务器检索CollectionViewCell的数据,但CollectionViewCell没有显示相关数据。
My tableViewCell show (Action, Drama) label and My CollectionViewCell show movies Name and Movie Image. I retrieve data for CollectionViewCell from server but CollectionViewCell didn't display related data.
推荐答案
在HomeVideoCell子类中清理 prepareforreuse中的数据
in HomeVideoCell Subclass clean up data in prepareforreuse
override func prepareForReuse() {
super.prepareForReuse()
self.movieTitle.text = ""
self.imageView.image = nil
}
