我想在UICollectionView中显示数据。哪个来自UITableView单元格。我主要关心的是这个。我正在通过另一个API中的catgID传递密钥cellForRowAt并从中获取数据。但是数据无法正确传输。
我正在从catgID传递cellForRowAt并进入另一个API，该API将显示UICollectionViewCells的数据列表。现在数据来了，但是方式不正确。
UITableView索引的tableview类。
import UIKit
import Reachability
import Alamofire
var arrayMenuProducts = [structMenuProducts]()
struct structMenuProducts {
var id:Int
var product_name:String
var category:String
var product_image:String
var price:String
var unit_price:Double
var addons:NSArray
}
class MenuVC: UIViewController, UITableViewDelegate, UITableViewDataSource {
var reachability = Reachability()!
@IBOutlet weak var tableview: UITableView!
var arrayMenuCat = [structMenuCat]()
struct structMenuCat{
var id:Int
var category_name:String
}
override func viewDidLoad() {
super.viewDidLoad()
menuVegAPI()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrayMenuCat.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
catgID = arrayMenuCat[indexPath.row].id
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell1") as! MenuTableCell
cell.lblCategoryTitle.text = arrayMenuCat[indexPath.row].category_name
cell.collectionviewOne.reloadData()
// let catid = arrayMenuCat[indexPath.row].id
// print(catid)
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 216
}
func menuVegAPI()
{
if (reachability.connection == .wifi) || (reachability.connection == .cellular)
{
arrayMenuCat.removeAll()
SwiftLoader.show(animated: true)
let url = BaseUrl + ViewController.sharedInstance.menuCategory
print(url)
Alamofire.request(url, method: .get, parameters: nil, encoding: URLEncoding.default).responseJSON { response in
SwiftLoader.hide()
switch response.result {
case .success:
let json = response.result.value
print(json)
let code = (json as AnyObject).object(forKey: "code") as! Int
print(code)
if code == 200
{
let data = (json as AnyObject).object(forKey: "data") as? NSArray
for alldata in data!
{
let id = (alldata as AnyObject).object(forKey: "id") as! Int
let category_name = (alldata as AnyObject).object(forKey: "category_name") as! String
let arr = structMenuCat(id: id, category_name: category_name)
self.arrayMenuCat.append(arr)
// self.menuProductsAPI(categoryid: id)
}
self.tableview.reloadData()
}
else
{
}
case .failure:
print("error")
}
}
}

alert(title: "", message: "Please Check Your Internet Connection")
}

}
TableViewCell类型的类。在本课程中，我向CollectionView显示数据。它的代码在这里
import UIKit
import Alamofire
import Reachability
var catgID : Int!
var collectionreload : UICollectionView?
class MenuTableCell: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegate {
var reachability = Reachability()!
@IBOutlet weak var lblCategoryTitle: UILabel!
@IBOutlet weak var collectionviewOne: UICollectionView!
var arrayMenuProducts = [structMenuProducts]()
struct structMenuProducts {
var id:Int
var product_name:String
var category:String
var product_image:String
var price:String
var unit_price:Double
var addons:NSArray
}
override func awakeFromNib() {
super.awakeFromNib()
collectionreload = self.collectionviewOne
print(arrayMenuProducts)
print(catgID ?? 0)
menuProductsAPI(categoryid: catgID!)
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return arrayMenuProducts.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CellRID", for: indexPath) as! MenuCollectionViewCell
let abc = arrayMenuProducts[indexPath.row].product_name
print(abc)
// if catgID == Int(arrayMenuProducts[indexPath.row].category)
// {
cell.lblTitleForVeg.text = arrayMenuProducts[indexPath.row].product_name
cell.lblForPriceVeg.text = "$\(arrayMenuProducts[indexPath.row].unit_price)"
}
func menuProductsAPI(categoryid:Int)
{
if (reachability.connection == .wifi) || (reachability.connection == .cellular)
{
SwiftLoader.show(animated: true)
arrayMenuProducts.removeAll()
let url = BaseUrl + ViewController.sharedInstance.menuProducts + "categoryid=\(categoryid)"
print(url)
Alamofire.request(url, method: .get, parameters: nil, encoding: JSONEncoding.default).responseJSON { response in
switch response.result {
case .success:
let json = response.result.value
print(json)
// self.tableview.reloadData()
let code = (json as AnyObject).object(forKey: "code") as! Int
print(code)
if code == 200
{
let data = (json as AnyObject).object(forKey: "data") as? NSArray
DispatchQueue.main.async {
for alldata in data!
{
let id = (alldata as AnyObject).object(forKey: "id") as! Int
let product_name = (alldata as AnyObject).object(forKey: "product_name") as! String
let category = (alldata as AnyObject).object(forKey: "category") as! String
let product_image = (alldata as AnyObject).object(forKey: "product_image") as! String
let price = (alldata as AnyObject).object(forKey: "price") as! String
let unit_price = (alldata as AnyObject).object(forKey: "unit_price") as! Double
let addons = (alldata as AnyObject).object(forKey: "addons") as? NSArray
let arr = structMenuProducts(id: id, product_name: product_name, category: category, product_image: product_image, price: price, unit_price: unit_price, addons: addons!)
self.arrayMenuProducts.append(arr)
}
self.collectionviewOne.reloadData()
SwiftLoader.hide()
}
}
else
{
}
case .failure:
print("error")
}
}
}
else
{
// alert(title: "", message: "Please Check Your Internet Connection")
}
}
}
我想以适当的格式显示来自CollectionView的数据。如果Tableview index == 0并且类别ID为10，则为。类别ID 10将首先按照我要传递类别ID的顺序依次排列。就我而言，类别ID不在队列中。
答案 0 :(得分：0)
将tableview数据源方法更新为
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell1") as! MenuTableCell
cell.lblCategoryTitle.text = arrayMenuCat[indexPath.row].category_name
cell.menuProductsAPI(categoryid: arrayMenuCat[indexPath.row].id)
return cell
}
然后从menuProductsAPI(categoryid: catgID!)方法中删除awakeFromNib
