我有一个TableView
带有两种单元格的单元格,都充满了一个CollectionView
. 在TableViewController
我让他们用一个简单的 if 语句显示。
我的TableViewController
:
import UIKit
import RealmSwift
import Alamofire
import SwiftyJSON
let myGroupLive = DispatchGroup()
let myGroupCommunity = DispatchGroup()
class HomeVTwoTableViewController: UITableViewController {
var headers = ["Live", "Channel1", "ChannelTwo", "Channel3", "Channel4", "Channel5", "Channel6"]
override func viewDidLoad() {
super.viewDidLoad()
DataController().fetchSomeDate(mode: "get")
DataController().fetchSomeOtherData(mode: "get")
}
//MARK: Custom Tableview Headers
override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return headers[section]
}
override func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int){
view.tintColor = UIColor.black
let header = view as! UITableViewHeaderFooterView
if section == 0 {
header.textLabel?.textColor = UIColor.black
view.tintColor = UIColor.white
}
else {
view.tintColor = UIColor.groupTableViewBackground
}
}
//MARK: DataSource Methods
override func numberOfSections(in tableView: UITableView) -> Int {
return headers.count
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
//Choosing the responsible PrototypCell for the Sections
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellBig", for: indexPath) as! HomeVTwoTableViewCell
return cell
}
else if indexPath.section == 1 {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellSmall", for: indexPath) as! HomeVTwoTableViewCellSmall
return cell
}
else {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellSmall", for: indexPath) as! HomeVTwoTableViewCellSmall
return cell
}
}
//Set custom cell height, has to match the CollectionView height
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if indexPath.section == 0 {
return 225.0
}
else {
return 120.0
}
}
}
我的TableViewCellSmall
:
import UIKit
import RealmSwift
var communities: Results<Community>?
class HomeVTwoTableViewCellSmall: UITableViewCell{
@IBOutlet weak var collectionView: UICollectionView!
}
extension HomeVTwoTableViewCellSmall: UICollectionViewDataSource,UICollectionViewDelegate {
//MARK: Datasource Methods
func numberOfSections(in collectionView: UICollectionView) -> Int
{
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int
{
return (communities?.count)!
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell
{
guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCellSmall", for: indexPath) as? HomeVTwoCollectionViewCellSmall else
{
fatalError("Cell has wrong type")
}
//Here I want my Sorting Statement to make unique content per collection view
//normal approach if no section is asked
let url : String = (communities?[indexPath.row].pictureUri)!
let name :String = (communities?[indexPath.row].communityName)!
cell.titleLbl.text = name
cell.imageView.downloadedFrom(link :"somelink")
return cell
}
//MARK: Delegate Methods
override func layoutSubviews() {
myGroupCommunity.notify(queue: DispatchQueue.main, execute: {
let realm = try! Realm()
communities = realm.objects(Community.self)
self.collectionView.dataSource = self
self.collectionView.delegate = self
})
}
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
do something
}
}
我现在的问题是,我希望“通道单元”在CollectionView
. 这意味着我需要某种密钥才能在正确的单元格中获取正确的数据。我的方法是使用 SectionHeader Title,但由于某些原因,我无法从TableViewCellSmall
. 所以我拥有所有单元格中的所有数据,没有我的密钥就无法对它们进行排序。
提前致谢。
