将值从 uitableview 传递到 uicollectionview

Question

如何将解析后的值从已在 UITableview 中使用的 url 传递到已在每个 UITableviews 单元格中使用的 UICollectionview（水平滚动）？我想用 swift 语言来做这件事。

我正在使用名为“collectionCat”的模型。

import Foundation

public class CollectionCat{



    var brandid:String = ""
    var brandname:String = ""
    var result:String = ""
    var noitems:String = ""



}

我也在使用 Alamofire 来解析来自 url 的数据。

override func viewDidLoad() {
    super.viewDidLoad()

    self.startActivityAnimating(message: "", type: NVActivityIndicatorType.BallClipRotate, color: AppColor.AppRed, padding: 10)
    Alamofire.request(.POST, "http://goringr.co.in/Mathrubhumi_project_ios/brand.php", parameters: ["": ""])
        .validate()
        .responseJSON { response in
            switch response.result {
            case .Success:
                print("Validation Successful")
                self.jsonResultParse(response.result.value!)
                self.stopActivityAnimating()
            case .Failure(let error):
                print(error)
                self.stopActivityAnimating()
                // return userCatagory
            }


    }


    // Do any additional setup after loading the view.
}
  if JSONArray.count != 0 {
        //_ = [UserCatagory]()


        for i:Int in 0 ..< JSONArray.count  {

            let jObject = JSONArray[i] as! NSDictionary

            let uCollect:CollectionCat = CollectionCat()
            uCollect.brandid = (jObject["brandid"] as AnyObject? as? String) ?? ""
            uCollect.brandname = (jObject["brandname"] as AnyObject? as? String) ?? ""
            uCollect.result = (jObject["result"] as AnyObject? as? String) ?? ""
            uCollect.noitems = (jObject["noitems"] as AnyObject? as? String) ?? ""

            collect.append(uCollect)
            print("collect COUNT ",collect.count)
        }

        self.newTable.reloadData()

    }



}

我不知道如何将存储的数据传输到 UICollection 视图，该视图位于上述 UITableview 的每个单元格中。

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
   // collectMaster = collect[indexPath.row]

    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as!  SecondHomeViewCell

   // collectMaster = CollectionCat()
    cell.get = ????

    return cell
}

谁能帮帮我？

SecondHomeViewCell 的代码是这样的。

import UIKit
import Kingfisher
import Alamofire
import NVActivityIndicatorView



class SecondHomeViewCell: UITableViewCell{

    @IBOutlet weak var collectionView: UICollectionView!



    var genre:CollectionCat? = nil{
    didSet {
                collectionView.reloadData()

            }

    }




     func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        //return genre!.brandid

       // return genre
        return 1
    }

    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("secondHome", forIndexPath: indexPath) as! SecondHomeCollectionViewCell

             if let genre = genre {
            cell.genre = genre.brandid[indexPath.row]

        }

        return cell
    }

    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
        let itemsPerRow:CGFloat = 4
        let hardCodedPadding:CGFloat = 5
        let itemWidth = (collectionView.bounds.width / itemsPerRow) - hardCodedPadding
        let itemHeight = collectionView.bounds.height - (2 * hardCodedPadding)
        return CGSize(width: itemWidth, height: itemHeight)
    }



}

Answer 1

在你的 ViewController 中添加一个数组，调用它

var collCat = [CollectionCat]()


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
   let collectMaster = collCat[indexPath.row]

    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as!  SecondHomeViewCell


    cell.brandID = collectMaster.brandid
    //and so on

    return cell
}

如果这不是您要寻找的答案，请告诉我。因为我想澄清，但我还没有能力发表评论。我需要达到 50 声望才能发表评论并要求澄清。

您可以通过在 UITableviewCell 自定义类中创建函数来将数据传递给集合视图

class SecondHomeViewCell: UITableViewCell{
//Array containing modals for particular tableview cell index path  


 var arrDataFromViewController = NSArray()
    func getData(arrData:NSArray){
        arrDataFromViewController = arrData
        collectionView.delegate = self
        collectionView.dataSource = self
        collectionView.reloadData()
        }


    @IBOutlet weak var collectionView: UICollectionView!



    var genre:CollectionCat? = nil{
    didSet {
                collectionView.reloadData()

            }

    }




     func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        //return genre!.brandid

       // return genre
        return 1
    }

    func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("secondHome", forIndexPath: indexPath) as! SecondHomeCollectionViewCell

             if let genre = genre {
            cell.genre = genre.brandid[indexPath.row]

        }

        return cell
    }

    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
        let itemsPerRow:CGFloat = 4
        let hardCodedPadding:CGFloat = 5
        let itemWidth = (collectionView.bounds.width / itemsPerRow) - hardCodedPadding
        let itemHeight = collectionView.bounds.height - (2 * hardCodedPadding)
        return CGSize(width: itemWidth, height: itemHeight)
    }



}

//现在在tableview数据源方法

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
   // collectMaster = collect[indexPath.row]

    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as!  SecondHomeViewCell

   // collectMaster = CollectionCat()
    cell.getData =  yourArray[indexPath.row]//Get Array data

    return cell
}
