我有一個用戶從UITable中選擇的實例。所選記錄有一個name
和一個id
與它關聯。如何從UITable DidSelectAtRow提取變量?
目前核實姓名和ID被正確地報道我使用
let tempCountryId = (self.newCountries[cellCountryId!])
print (tempCountryId)
國家(名稱:可選( 「英格蘭」),countryId:可選( 「5」))
我希望能夠是countryId存儲在一個變量,所以我可以重新填充我的數據(足球部門)UITable匹配countryId「5」
我怎麼做是個是什麼?
這是我完整的腳本:
import UIKit
class PickTeamViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet weak var teamsTableView: UITableView!
var pickedCountryID: Int?
var selectedCellCountryTitle: String?
var cellCountryId: Int?
struct Country {
var name: String?
var countryId: String?
init(_ dictionary: [String : String]) {
self.name = dictionary["name"]
self.countryId = dictionary["id"]
}
}
struct Divisions {
var divisionName: String?
var divisionId: String?
init(_ dictionary: [String : String]) {
self.divisionName = dictionary["name"]
self.divisionId = dictionary["country_id"]
}
}
struct Teams {
var teamName: String?
var newTeamId: String?
init(_ dictionary: [String : String]) {
self.teamName = dictionary["name"]
}
}
struct TeamId {
var newTeamId: String?
init(_ dictionary: [String : String]) {
self.newTeamId = dictionary["id"]
}
}
var newCountries = [Country]()
var newDivisions = [Divisions]()
var newTeams = [Teams]()
var newTeamId = [TeamId]()
override func viewDidAppear(_ animated: Bool) {
let myUrl = URL(string: "http://www.quasisquest.uk/KeepScore/getTeams.php?");
var request = URLRequest(url:myUrl!);
request.httpMethod = "GET";
let task = URLSession.shared.dataTask(with: myUrl!) { (data: Data?, response: URLResponse?, error: Error?) in
DispatchQueue.main.async
{
if error != nil {
print("error=\(error)")
return
}
do{
let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as? [String:Any]
print (json)
if let arr = json?["countries"] as? [[String:String]] {
self.newCountries = arr.flatMap { Country($0) }
self.teamsTableView.reloadData()
}
if let arr = json?["divisions"] as? [[String:String]] {
self.newDivisions = arr.flatMap { Divisions($0) }
}
if let arr = json?["teams"] as? [[String:String]] {
self.newTeams = arr.flatMap { Teams($0) }
}
self.teamsTableView.reloadData()
} catch{
print(error)
}
}
}
task.resume()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.newCountries.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let country = newCountries[indexPath.row]
let cell = UITableViewCell()
cell.textLabel?.text = country.name
cell.textLabel?.font = UIFont(name: "Avenir", size: 12)
cell.textLabel?.textColor = UIColor.black
cell.backgroundColor = UIColor.white
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
cellCountryId = indexPath.row
// print (self.newCountries[cellCountryId!])
let tempCountryId = (self.newCountries[cellCountryId!])
print (tempCountryId)
}
override func viewDidLoad() {
super.viewDidLoad()
self.teamsTableView.delegate = self
self.teamsTableView.dataSource = self
// Do any additional setup after loading the view.
}
}
如果所選記錄已經在所選記錄中又名「TableViewCell」,那麼你想在哪裏顯示它? – Adeel
我不確定你的意思。但理想情況下,當選擇記錄時,將使用countryId'5'來刷新UITable與單獨數組中的數據,我也存儲了 – RDowns
是否要顯示在相同的國家/地區選擇的詳細信息'TableView'? – Adeel
