我需要用滑块中的值更新单元格。滑块正在从解析的JSON数据中提取数据。
如何将滑块中的显示JSON数据添加到tableview单元格?
这是我当前的代码:

import UIKit

class SliderViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

@IBOutlet weak var sliderTableView: UITableView!
@IBOutlet weak var styleSlider: UISlider!
@IBOutlet weak var abvSlider: UISlider!
@IBOutlet weak var ibuSlider: UISlider!
@IBOutlet weak var testLabel: UILabel!

@IBAction func styleSlider(_ sender: Any) {
// LABEL CREATED FOR TESTING PURPOSES ONLY
    testLabel.text = String(Int(styleSlider.value))
}

var beersMatch = [Beer]()
var filteredBeersMatch = [Beer]()
var filters = [BeerStyle]()
var selectedCells: [Bool] = []
let apiManager = APIManager()

override func viewDidLoad() {
    super.viewDidLoad()

    apiManager.TapList { (fetchedBeers) in
        self.beersMatch = fetchedBeers

        var setFilters = Set<BeerStyle>()
        for beer in fetchedBeers {
            setFilters.insert(beer.StyleName)
        }

        self.filters = Array(setFilters)

        DispatchQueue.main.async {
            self.sliderTableView.reloadData()
        }
    }
}

// MARK: Table view data source
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int)
-> Int {
return filteredJsonMatch.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath)
-> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier:
"SliderListCell") as? SliderTableViewCell else {
    return UITableViewCell()
}

// MARK: Beer name
let beers = filteredJsonMatch[indexPath.row]
cell.sliderMatchLabel.text = beers.BrewName
cell.sliderMatchName.text = beers.BevName
cell.sliderMatchRowNumber.text = jsons.DisplayName

if let IBU = beers.Ibu {
    cell.sliderMatchIBU.text = "\(IBU) IBU"
}

if let ABV = beers.Abv {
    cell.sliderMatchABV.text = "\(ABV)%"
}

cell.sliderMatchJsonType.text = jsons.StyleName.name
cell.sliderMatchLocation.text = jsons.Location
cell.sliderMatchKegImage.image = jsons.kegPercentageFull()

// MARK: Download image
jsons.downloadImage { (jsonImage) in
    DispatchQueue.main.async {
        cell.sliderMatchImage.image = jsonImage
    }
}
return cell
}

最佳答案

你的filteredJsonMatch是什么?当你在filters数组中添加啤酒时,它不应该是filters吗?
在您的TapList闭包中:

var setFilters = Set<BeerStyle>()
for beer in fetchedBeers {
   setFilters.insert(beer.StyleName)
}

self.filters = Array(setFilters)

但在将数据填充到每个单元格时:
let beers = filteredJsonMatch[indexPath.row]
