我的tableview
由name
属性排序。因此,如果我输入名称“ Hanna”,然后输入“ Belle”,则tableview
将如下所示:
美女
汉娜
但是当我选择一个单元格时,由于我输入的顺序,我会显示另一单元格的数据。我该如何解决?
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,我将编辑我的问题。
在cellForRowAt
内部,您使用fetchedResultsController
let pet = fetchedResultsController.object(at: indexPath)
但是在didSelectRowAt
内使用pets
vc.pet = pets[indexPath.row]
两者都必须使用相同的数组
