Tableview 行未按顺序显示 swift 中的附加值
Tableview rows are not showing inorder with added values in swift
我在配置文件视图控制器中收到 JSON 响应。最初 JSON 包含一个我需要在表视图中显示的地址，然后我从第三个 viewcontroller 添加新地址首先 viewcontroller JSON...
现在我需要在配置文件中更新初始地址和所有添加的新地址 viewcontroller INORDER.. 怎么样？
如果我在配置文件中添加如下内容viewcontroller，那么表格视图不会按地址顺序显示：这里初始地址下降，添加的新地址也分散.. ...我需要初始地址位于索引 0，新地址位于索引 1...

这是 ProfileModel 代码：

从这个viewcontroller我添加新地址到配置文件viewcontroller tableview:

self.previousLocation = center
let userLocation :CLLocation = center as CLLocation
latitudeZoom = userLocation.coordinate.latitude
logitudeZoom = userLocation.coordinate.longitude
geoCoder.reverseGeocodeLocation(center) { [weak self] (placemarks, error) in
guard let self = self else { return }
self.streetNumber = placemark.subThoroughfare ?? ""
self.streetName = placemark.thoroughfare ?? ""
self.localityName = placemark.locality ?? ""//locality
self.sublocalityName = placemark.subLocality ?? ""//locality
self.zipName = placemark.postalCode ?? ""//locality
}
}
@IBAction func popupSubmitBtn(_ sender: Any) {

self.saveaddAddressService()
}
}
func saveaddAddressService(){
let parameters: [String: Any] = [
"pincode": zipName,
"city": localityName,

]
do {
let jsonObject = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String: Any]
print("saved address json \(jsonObject)")
self.addAddrsID = jsonObject["addressId"] as! String
UserDefaults.standard.set(self.addAddrsID, forKey: "addAddress")
DispatchQueue.main.async {
let viewController = self.storyboard?.instantiateViewController(withIdentifier: "ProfileViewController") as! ProfileViewController
self.navigationController?.pushViewController(viewController, animated: true)

profileviewcontroller json 响应：所有地址的用户 ID 相同.. 但对于每个新地址都会有新的 addressid

在您的模型中 ProfileModelUserAddress 添加一个新变量来保存 dateCreated:
class ProfileModelUserAddress : NSObject, NSCoding{
// add this variable
var dateCreated : Date!
//.... your other variables
init(fromDictionary dictionary: [String:Any]){
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy HH:mm:ss"
//convert your string to date
dateCreated = formatter.date(from: dictionary["dateCreated"] as! String)
//....the rest of your code
}
}
然后在你的 ProfileViewController
class ProfileViewController: UIViewController, MyCellDelegate {
var userModel : ProfileModel?
// added this array which will hold all your addresses
var addressModel = [ProfileModelUserAddress]()
func getUserProfile() {
// if you call this fucntion again everytime you add
// a new address, call removeAll() in order to have an
//empty array, otherwise you will end up with double values.
self.addressModel.removeAll()
//.... rest of your code
let jsonObject = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String :AnyObject]
self.userModel = ProfileModel.init(fromDictionary: jsonObject)
for address in userModel!.userAddresses! {
addressModel.append(address)
}
self.addressModel.sort(by: { [=11=].dateCreated!.compare(.dateCreated!) == .orderedDescending})
//.....
//.... rest of your code
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// rest of your code ....
// You can use your addresses array
let addr = self.addressModel[indexPath.row]
// rest of your code ....
}
}
我测试了它并且有效：
