无法在TableViewCell.Data中显示事件报告中的数据，但是当您打开数组“sports”时，以cels为单位显示数据。显示标题显示并且传输结束...
这是我的json代码......
Event.swift
import UIKit
struct Event {
let match : String
let forecast : String
let data : String
let image : UIImage
var sports : [Sport]
init (match : String, forecast : String, data: String, image : UIImage, sports : [Sport]) {
self.match = match
self.forecast = forecast
self.data = data
self.image = image
self.sports = sports
}
static func eventsFromBundle ()-> [Event] {
var events = [Event] ()
guard let url = Bundle.main.url(forResource: "events", withExtension: "json") else {
return events
}
do {
let data = try Data(contentsOf: url)
guard let rootObject = try JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [String : Any] else {
return events
}
guard let eventObjects = rootObject["events"] as? [[String: AnyObject]] else {
return events
}
for eventObject in eventObjects {
if let match = eventObject["match"] as? String,
let forecast = eventObject["forecast"] as? String,
let data = eventObject["data"] as? String,
let imageName = eventObject["image"] as? String,
let image = UIImage(named: imageName),
let sportsObject = eventObject["sports"] as? [[String : String]]{
var sports = [Sport]()
for sportObject in sportsObject {
if let nameTitle = sportObject["name"] ,
let titleName = sportObject["image"],
let titleImage = UIImage(named: titleName + ".jpg"),
let prognozLabel = sportObject["prognoz"],
let obzor = sportObject["obzor"] {
sports.append(Sport(name: nameTitle, prognoz: prognozLabel, image: titleImage, obzor: obzor, isExpanded: false))
}
}
let event = Event(match: match, forecast: forecast, data: data, image: image, sports: sports)
events.append(event)
}
}
} catch {
return events
}
return events
}
}
import UIKit
class SportViewController: BaseViewController {
var events = Event.eventsFromBundle ()
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
addSlideMenuButton()
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 100
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
NotificationCenter.default.addObserver(forName: .UIContentSizeCategoryDidChange, object: .none, queue: OperationQueue.main) { [weak self] _ in
self?.tableView.reloadData()
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? SportDetailViewController,
let indexPath = tableView.indexPathForSelectedRow {
destination.selectedEvent = events[indexPath.row]
}
}
}
extension SportViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return events.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellMatch", for: indexPath) as! SportTableViewCell
let event = events[indexPath.row]
cell.matchLabel.text = event.match
cell.imageMatch.image = event.image
cell.forecastLabel.text = event.forecast
cell.dataLabel.text = event.data
cell.matchLabel.font = UIFont.preferredFont(forTextStyle: .subheadline)
cell.forecastLabel.font = UIFont.preferredFont(forTextStyle: .callout)
return cell
}
}
她是controller.SportDetailViewController.swift
import UIKit
class SportDetailViewController: UIViewController {
var selectedEvent : Event!
let obzorText = "Select for more info >"
@IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
title = selectedEvent.match
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 300
// Do any additional setup after loading the view.
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
}
}
extension SportDetailViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return selectedEvent.sports.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell : SportDetailTableViewCell = tableView.dequeueReusableCell(withIdentifier: "cellMatch", for: indexPath) as! SportDetailTableViewCell
let sport = selectedEvent.sports[indexPath.row]
cell.nameTitle.text = sport.name
cell.titleImage.image = sport.image
cell.prognozLabel.text = sport.prognoz
cell.selectionStyle = .none
cell.nameTitle.backgroundColor = UIColor.darkGray
cell.backgroundColor = UIColor.red
cell.obzorText.text = sport.isExpanded ? sport.obzor : obzorText
cell.obzorText.textAlignment = sport.isExpanded ? .left : .center
return cell
}
}
extension SportDetailViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
guard let cell = tableView.cellForRow(at: indexPath) as? SportDetailTableViewCell else { return }
var sport = selectedEvent.sports[indexPath.row]
sport.isExpanded = !sport.isExpanded
selectedEvent.sports[indexPath.row] = sport
cell.obzorText.text = sport.isExpanded ? sport.obzor : obzorText
cell.obzorText.textAlignment = sport.isExpanded ? .left : .center
tableView.beginUpdates()
tableView.endUpdates()
tableView.scrollToRow(at: indexPath, at: .top, animated: true)
}
}
所有这些方法都尝试过：tableview.datasource = self，tableview.delegate =selfиreloadData（）..... in viewDidLoad。
答案 0 :(得分：0)
从init中删除此struct :(因为struct获得免费初始化程序）
init (match : String, forecast : String, data: String, image : UIImage, sports : [Sport]) {
self.match = match
self.forecast = forecast
self.data = data
self.image = image
self.sports = sports
}
现在，由于您在类范围内调用方法，因此不会填充var events。所以改变这个：
class SportViewController: BaseViewController {
var events = Event.eventsFromBundle ()
...
...
}
到
class SportViewController: BaseViewController {
var events = [Event]()
...
...
override func viewDidLoad() {
super.viewDidLoad()
addSlideMenuButton()
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 100
events = Event().eventsFromBundle()
}
...
...
}
这可以解决您的问题。
