我有3天的时间了，我找不到使保存状态运行功能的方法。
所以基本上这是我的保存状态
这是我在用户登录应用后写用户/驱动程序的方式，JSON返回用户/驱动程序密钥并为海底事件做准备
右波纹管
if emailcapturado == emailText {
（用于方便的位置**）
@IBAction func iniciarSesion(_ sender: UIButton) {
guard
let emailText = Email.text, !emailText.isEmpty,
let contrasenaText = Contrasena.text, !contrasenaText.isEmpty else
{
displayAlert(title: "Información Faltante", message: "Debes porporcionar un correo y contraseña")
return
}
let myURL = URL(string: "hehe")
var request = URLRequest(url: myURL!)
request.httpMethod = "POST"
let posString = "Email=\(emailText)&Password=\(contrasenaText)"
request.httpBody = posString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) {
data, response, error in
if let error = error {
DispatchQueue.main.async {
self.displayAlert(title: "Usuario", message: "Error de conexion")
}
print("error=\(error)")
return
}
guard let data = data else {
DispatchQueue.main.async {
self.displayAlert(title: "Usuario", message: "Error de conexion")
}
print("Something wrong")
return
}

DispatchQueue.main.async {
self.displayAlert(title: "Usuario", message: "Error de conexion")
}
print("Error: Couldn't decode data into Blog:", error)
return
}
}
task.resume()
}
应用代理：
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
check()
checkuser()
}
用于检查我先前在AppDelegate中设置的值的功能
func check() {
if UserDefaults.standard.value(forKey: "nivelChofer") != nil
{
let VC = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "ConductorPrincipalViewController")
let navVC = UINavigationController(rootViewController: VC)
let share = UIApplication.shared.delegate as? AppDelegate
share?.window?.rootViewController = navVC
share?.window?.makeKeyAndVisible()
}
}
func checkuser() {
if UserDefaults.standard.value(forKey: "nivelUser") != nil
{
let VC = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "UnaVezLogeadoViewController")
let navVC = UINavigationController(rootViewController: VC)
let share = UIApplication.shared.delegate as? AppDelegate
share?.window?.rootViewController = navVC
share?.window?.makeKeyAndVisible()
}
}
这是我编写密钥以准备驱动程序VC““ ConductorPrincipalViewController”“中的保存状态的方式 （以便于定位）
if blog.Response == "1" {
正下方
@objc func consultarViaje(){
let idcho = UserDefaults.standard.string(forKey: "idChofer")
let myURL = URL(string: "hee hee")
var request = URLRequest(url: myURL!)
request.httpMethod = "POST"
let posString = "ID_Conductor=\(idcho!)"
request.httpBody = posString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) {
data, response, error in
if let error = error {
print("error=\(error)")
return
}
guard let data = data else {
print("Something wrong")
return
}
struct Blog: Decodable {
let Response: String
let articles: [Article]
enum CodingKeys : String, CodingKey {
case Response = "Response"
case articles = "Perfil"
}
}
struct Article: Decodable {
}
do {
let blog = try JSONDecoder().decode(Blog.self, from: data)
// si el pasajero acepta el viaje se queda guardado el PUNTO DONDE EL CONDUCTOR VAA IR POR EL PASAJERO JEJE y es igual a 1
//
DispatchQueue.main.async {
if blog.Response == "1" {
self.displayAlert(title: "Información..", message: "¡El pasajero aceptó!")
UserDefaults.standard.set("1", forKey: "saveState")// KEY FOR SAVE POINT
print("el pasajero acepto")
self.helloWorldTimer2?.invalidate()
self.helloWorldTimer2 = nil
self.enviarCotizacion.isHidden = true
self.cotizacionUitext.isHidden = true
self.accionEnviar.isHidden = true
self.irAlPasajero.isHidden = false
}
else if (blog.Response == "0")
{
print("esperando..")
}
else if (blog.Response == "2")
{
self.displayAlert(title: "Información..", message: "El pasajero canceló la solicitud")
print("el pasajero rechazo")
self.helloWorldTimer2?.invalidate()
self.helloWorldTimer2 = nil
self.enviarCotizacion.isHidden = true
self.cotizacionUitext.text = ""
self.cotizacionUitext.isHidden = true
self.accionEnviar.isHidden = true
let allAnnotations = self.map.annotations
self.map.removeAnnotations(allAnnotations)
self.map.removeOverlays(self.map.overlays)
self.helloWorldTimer = Timer.scheduledTimer(timeInterval: 30.0, target: self, selector: #selector(ConductorPrincipalViewController.ConsultarSolicitudes), userInfo: nil, repeats: true)
}
else {
print("error")
self.displayAlert(title: "ERROR..", message: "ERROR")
}
}
}
catch {
print("Error: Couldn't decode data into Blog:", error)
print(error)
return
}
}
task.resume()
}
所以我想在我的“ ConductorPrincipalViewController” VC中做什么 是使此功能可以运行如果用户关闭应用程序（保存状态）
func saveState()
{
let oli = UserDefaults.standard.value(forKey: "saveState") as! String
if (oli == "1")
{
self.helloWorldTimer2?.invalidate()
self.helloWorldTimer2 = nil
self.enviarCotizacion.isHidden = true
self.cotizacionUitext.isHidden = true
self.accionEnviar.isHidden = true
self.irAlPasajero.isHidden = false
}
}
我试图在 AppDelegate 中创建另一个函数来调用 saveState（）
func checkSaveStatechofer()
{
if UserDefaults.standard.value(forKey: "saveState") != nil
{
let VC = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "ConductorPrincipalViewController")
let navVC = UINavigationController(rootViewController: VC)
let share = UIApplication.shared.delegate as? AppDelegate
share?.window?.rootViewController = navVC
share?.window?.makeKeyAndVisible()
}
}
AppDelegate功能无法调用checkSaveStatechofer（）
let VC = UIStoryboard(name: "Main", bundle: Bundle.main).instantiateViewController(withIdentifier: "ConductorPrincipalViewController")
VC获得调用，但没有运行该函数
