>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，然后我正在将新地址从第三视图控制器添加到第一个视图控制器 JSON...
现在初始地址和所有添加的新地址都需要在配置文件视图控制器INORDER中更新..如何？
如果我在配置文件视图控制器中添加如下内容，则表视图不会按地址顺序显示：这里的初始地址下降并添加了新地址也分散了.....我需要初始地址位于索引 0，新地址位于索引 1...
class ProfileViewController: UIViewController, MyCellDelegate {
@IBOutlet var addressTableview: UITableView!
var userModel : ProfileModel?
override func viewWillAppear(_ animated: Bool) {
self.navigationController?.navigationBar.isHidden=true
DispatchQueue.main.async {
self.getUserProfile()
}
}
func getUserProfile() {
let urlStr = urlComponents?.url
let request = NSMutableURLRequest(url: urlStr!, cachePolicy: .useProtocolCachePolicy,timeoutInterval: 10.0)
request.httpMethod = "POST"
let session = URLSession.shared
let dataTask = session.dataTask(with: request as URLRequest, completionHandler: { (data, response, error) -> Void in
if error == nil {
let httpResponse = response as? HTTPURLResponse
if httpResponse!.statusCode == 200 {
do {
let jsonObject = try JSONSerialization.jsonObject(with: data!, options: .mutableLeaves) as! [String :AnyObject]
self.userModel = ProfileModel.init(fromDictionary: jsonObject)
if (self.userModel?.userId) != nil {
DispatchQueue.main.async {
self.addressTableview.reloadData()
}
}
} catch { print(error.localizedDescription) }
})
dataTask.resume()
}
}
extension ProfileViewController : UITableViewDelegate,UITableViewDataSource, CLLocationManagerDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return userModel?.userAddresses.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell: AddresCell = tableView.dequeueReusableCell(withIdentifier: "AddresCell", for: indexPath) as! AddresCell
let addr = userModel?.userAddresses![indexPath.row]
cell.name.text = addr?.type
cell.typeAddLabel.text = addr?.addressName
let street = addr?.streetName
let colony = addr?.colony
let city = addr?.city
let pincode = addr?.pincode
let locality: String = addr?.buildingName ?? ""
let dorNum: String = addr?.houseNo ?? ""
cell.address.text = street! + "," + colony! + "," + city! + "," + pincode! + "," + locality + "," + dorNum
return cell
}
}
我错在哪里，我如何按顺序制作表视图行，请不要介意我被困在这里很长时间了
这是配置文件模型代码：
class ProfileModel : NSObject, NSCoding{
var userId : String!
var userAddresses : [ProfileModelUserAddress]!
init(fromDictionary dictionary: [String:Any]){
userId = dictionary["userId"] as? String
userAddresses = [ProfileModelUserAddress]()
if let userAddressesArray = dictionary["userAddresses"] as? [[String:Any]]{
for dic in userAddressesArray{
let value = ProfileModelUserAddress(fromDictionary: dic)
userAddresses.append(value)
}
}
}
func toDictionary() -> [String:Any]
{
var dictionary = [String:Any]()
if userId != nil{
dictionary["userId"] = userId
}
if userAddresses != nil{
var dictionaryElements = [[String:Any]]()
for userAddressesElement in userAddresses {
dictionaryElements.append(userAddressesElement.toDictionary())
}
dictionary["userAddresses"] = dictionaryElements
}
return dictionary
}
@objc required init(coder aDecoder: NSCoder)
{
userId = aDecoder.decodeObject(forKey: "userId") as? String
userAddresses = aDecoder.decodeObject(forKey: "userAddresses") as? [ProfileModelUserAddress]
}
@objc func encode(with aCoder: NSCoder)
{
if userId != nil{
aCoder.encode(userId, forKey: "userId")
}
if userAddresses != nil{
aCoder.encode(userAddresses, forKey: "userAddresses")
}
}
}
ProfileModelvar userAddresses : [ProfileModelUserAddress]的代码：
class ProfileModelUserAddress : NSObject, NSCoding{
var addressId : String!
var addressName : String!
var userId : String!
var pincode : String!
var city : String!
var streetName : String!
init(fromDictionary dictionary: [String:Any]){
addressId = dictionary["addressId"] as? String
addressName = dictionary["addressName"] as? String
userId = dictionary["userId"] as? String
pincode = dictionary["pincode"] as? String
city = dictionary["city"] as? String
streetName = dictionary["streetName"] as? String
}
func toDictionary() -> [String:Any]
{
var dictionary = [String:Any]()
if addressId != nil{
dictionary["addressId"] = addressId
}
if addressName != nil{
dictionary["addressName"] = addressName
}
if userId != nil{
dictionary["userId"] = userId
}
if pincode != nil{
dictionary["pincode"] = pincode
}
if city != nil{
dictionary["city"] = city
}
if streetName != nil{
dictionary["streetName"] = streetName
}
return dictionary
}
@objc required init(coder aDecoder: NSCoder)
{
addressId = aDecoder.decodeObject(forKey: "addressId") as? String
addressName = aDecoder.decodeObject(forKey: "addressName") as? String
userId = aDecoder.decodeObject(forKey: "userId") as? String
pincode = aDecoder.decodeObject(forKey: "pincode") as? String
city = aDecoder.decodeObject(forKey: "city") as? String
streetName = aDecoder.decodeObject(forKey: "streetName") as? String
}
@objc func encode(with aCoder: NSCoder)
{
if addressId != nil{
aCoder.encode(addressId, forKey: "addressId")
}
if addressName != nil{
aCoder.encode(addressName, forKey: "addressName")
}
if userId != nil{
aCoder.encode(userId, forKey: "userId")
}
if pincode != nil{
aCoder.encode(pincode, forKey: "pincode")
}
if city != nil{
aCoder.encode(city, forKey: "city")
}
if streetName != nil{
aCoder.encode(streetName, forKey: "streetName")
}
}
}
从这个视图控制器，我正在向配置文件视图控制器表视图添加新地址：
class NewZoomAddressViewController: UIViewController {
func mapView(_ mapView: MKMapView, regionDidChangeAnimated animated: Bool) {
let center = getCenterLocation(for: mapView)
let geoCoder = CLGeocoder()
guard let previousLocation = self.latestLocation else { return }
guard center.distance(from: previousLocation) > 50 else { return }
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) {
if addressTextfield != nil{
self.saveaddAddressService()
}
}
func saveaddAddressService(){
let parameters: [String: Any] = [
"pincode": zipName,
"city": localityName,
"streetName": sublocalityName,
"colony": "",
"location" : locations,
"addressName" : addressTextfield.text
]
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)
}
} catch { print(error.localizedDescription) }
} else {
}
}
})
dataTask.resume()
}
}
配置文件视图控制器 JSON 响应：所有地址都相同的用户 ID.. 但对于每个新地址，都会有新的地址 ID
{
addressId = 5ef48787f546e73ee823f032;
addressName = ban;
city = Bengaluru;
dateCreated = "25-06-2020 16:46:23";
dateModified = "25-06-2020 16:46:23";
pincode = 560001;
userId = 85dc157688d84aab9bbbab150cbc13da;
},
{
addressId = 5ef48828f546e73ee823f033;
addressName = chen;
dateCreated = "25-06-2020 16:49:04";
landMark = "";
pincode = 600095;
streetName = Maduravoyal;
userId = 85dc157688d84aab9bbbab150cbc13da;
},
{
addressId = 5ef46670f546e73ee823f020;
addressName = vizag;
city = Visakhapatnam;
colony = "";
dateCreated = "25-06-2020 14:25:12";
pincode = 530045;
userId = 85dc157688d84aab9bbbab150cbc13da;
},
{
addressId = 5ef4664af546e73ee823f01c;
在模型中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: { $0.dateCreated!.compare($1.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，它可以工作：
func getUserProfile() {
// All dictionaries have the same values except for the date
let address1 = ["addressId" : "5ef48828f546e73ee823f033", "addressName": "chen","dateCreated": "25-06-2020 16:49:04", "landMark": "", "pincode": "879327" ,"streetName": "Maduravoyal", "userId": "947384783749" ]
let address2 = ["addressId" : "5ef48828f546e73ee823f033", "addressName": "chen","dateCreated": "27-06-2020 16:49:04", "landMark": "", "pincode": "879327" ,"streetName": "Maduravoyal", "userId": "947384783749" ]
let address3 = ["addressId" : "5ef48828f546e73ee823f033", "addressName": "chen","dateCreated": "25-06-2020 19:49:04", "landMark": "", "pincode": "879327" ,"streetName": "Maduravoyal", "userId": "947384783749" ]
let address4 = ["addressId" : "5ef48828f546e73ee823f033", "addressName": "chen","dateCreated": "29-06-2020 19:49:04", "landMark": "", "pincode": "879327" ,"streetName": "Maduravoyal", "userId": "947384783749" ]
let addressObj = ProfileModelUserAddress.init(fromDictionary: address1)
let addressObj1 = ProfileModelUserAddress.init(fromDictionary: address2)
let addressObj2 = ProfileModelUserAddress.init(fromDictionary: address3)
let addressObj3 = ProfileModelUserAddress.init(fromDictionary: address4)
var addresseTry = [ProfileModelUserAddress]()
addresseTry.append(addressObj)
addresseTry.append(addressObj1)
addresseTry.append(addressObj2)
addresseTry.append(addressObj3)
for address in addresseTry {
addressModel.append(address)
}
self.addressModel.sort(by: { $0.dateCreated!.compare($1.dateCreated!) == .orderedDescending})
for addressForDate in self.addressModel {
print(addressForDate.dateCreated)
}
}
其中打印：
