如何 select didSelectRowAt indexPath 中的正确实体

How to select the correct entity in didSelectRowAt indexPath

我的 tableviewname 属性排序。因此,如果我输入名称 "Hanna",那么 "Belle" tableview 将如下所示:


Belle


Hanna


但是当我 select 一个单元格时,另一个单元格的数据会显示,因为我猜是因为我输入它的顺序。我该如何解决这个问题?

MainTableViewController.swift

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? MainTableViewCell

    let pet = fetchedResultsController.object(at: indexPath)

    cell?.nameLB.text = pet.name
    if pet.isDog {
        cell?.isDogString = "dog"
        cell?.petImage.image = UIImage(named: "dog.png")
    } else {
        cell?.isDogString = "cat"
        cell?.petImage.image = UIImage(named: "cat.png")
    }
    if pet.isBoy {
        cell?.backgroundColor = UIColor(red: 102/255, green: 230/255, blue: 255/255, alpha: 1.0)
    } else {
        cell?.backgroundColor = UIColor(red: 255/255, green: 153/255, blue: 255/255, alpha: 1.0)
    }
    return cell!
}

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let vc = storyboard?.instantiateViewController(withIdentifier: "PetSelectedViewController") as! PetSelectedViewController
    vc.pet = pets[indexPath.row]
    _ = navigationController?.pushViewController(vc, animated: true)
}

PetSelectedViewController.swift

var pet: Pet! // entity

override func viewDidLoad() {
    super.viewDidLoad()
    basicPetInfoUI()
    loadData()
}

func loadData() {
    var isBoyString = ""
    var isVaccString = ""
    pet!.isBoy ? (isBoyString = "Boy") : (isBoyString = "Girl")
    pet!.isVaccinated ? (isVaccString = "Vaccinated") : (isVaccString = "Not Vaccinated")
    nameLabel.text = pet.name
    breedLabel.text = pet.breed
    isBoyLabel.text = isBoyString
    isVaccinatedLabel.text = isVaccString
    weightLabel.text = pet.weight
}

如果需要更多信息,请告诉我,我会编辑我的问题。

cellForRowAt 你使用 fetchedResultsController

let pet = fetchedResultsController.object(at: indexPath)

但是在 didSelectRowAt 里面你使用 pets

vc.pet = pets[indexPath.row]

你必须在两者中使用相同的数组
