iOS TuyaSDK 设备配对Delegate回调无法触发问题

我是iOS开发新手，正在使用TuyaSDK开发IoT应用（已完成Android版本）。设备能正常完成配对，但Delegate类的protocol方法始终无法进入，无法监听配对成功或失败的状态反馈。

原代码

import SwiftUI
import TuyaSmartHomeKit
import TuyaSmartDeviceKit
import Toast
import TuyaSmartActivatorKit

struct HomeDevices: View{
    
    @State var homeId: Int64 = 0
    @State var token: String = ""
    @State var devId: String = ""
    @State var device: TuyaSmartDevice?
 
    let homeManager: TuyaSmartHomeManager = TuyaSmartHomeManager()
    
    var body: some View {
        VStack{
            Button("Crear casa"){
                addHome()
            }.font(.title2)
                .fontWeight(.bold)
                .frame(width:150, height:20)
                .foregroundColor(.white)
                .padding()
                .background(Color("colorbotones"))
                .cornerRadius(16)
                .shadow(color: .gray, radius: 5, x: 0, y: 5)
                .offset(y:-100)
            Button("Encender"){
                publishDps(estado : true)
            }.font(.title2)
                .fontWeight(.bold)
                .frame(width:150, height:20)
                .foregroundColor(.white)
                .padding()
                .background(Color("colorbotones"))
                .cornerRadius(16)
                .shadow(color: .gray, radius: 5, x: 0, y: 5)
                .offset(y:30)
            
            Button("Apagar"){
                publishDps(estado : false)
            }.font(.title2)
                .fontWeight(.bold)
                .frame(width:150, height:20)
                .foregroundColor(.white)
                .padding()
                .background(Color("colorbotones"))
                .cornerRadius(16)
                .shadow(color: .gray, radius: 5, x: 0, y: 5)
                .offset(y:90)
        }
    }
    
    func addHome() {
        homeManager.addHome(withName: "Home",
                            geoName: "Bolivia",
                            rooms: ["Quantum"],
                            latitude: 0,
                            longitude: 0,
                            success: { (homeId) in
            print("add home success")
            print(homeId)
            getToken(homeId: homeId)
        }) { (error) in
            if let e = error {
                print("add home failure: \(e)")
            }
        }
    }
    
    func getToken(homeId : Int64){
        TuyaSmartActivator.sharedInstance()?.getTokenWithHomeId(homeId, success: { (token) in
            print("getToken success: \(String(describing: token))")
            startConfigWiFi(token: token!)
        }, failure: { (error) in
            if let e = error {
                print(homeId)
                print("getToken failure: \(e)")
            }
        })
    }
    
    func startConfigWiFi(token: String) {
        let delegate = tuyaSmartActivatorDelegate.init()
        delegate.StartSync(token: token)
    }

    func publishDps(estado : Bool) {
        device = TuyaSmartDevice(deviceId: "eb153db66617bd33e5dvi1") //手动传入设备ID

        let dps = ["1" : estado]
        device?.publishDps(dps, success: {
             print("publishDps success")
        }, failure: { (error) in
            if let e = error {
                print("publishDps failure: \(e)")
            }
        })
    }
}

struct HomeDevices_Previews: PreviewProvider {
    static var previews: some View {
        HomeDevices()
    }
}

class tuyaSmartActivatorDelegate: NSObject, TuyaSmartActivatorDelegate {
    override init() {
        super.init()
        TuyaSmartActivator.sharedInstance().delegate = self
    }
    
    func StartSync(token:String){
        TuyaSmartActivator.sharedInstance()?.startConfigWiFi(TYActivatorModeEZ, ssid: "QUANTUM", password: "almacenqnt22*", token: token, timeout: 1000)
    }
    
    //MARK: - TuyaSmartActivatorDelegate
    //代码从未进入这个方法
    func activator(_ activator: TuyaSmartActivator!, didReceiveDevice deviceModel: TuyaSmartDeviceModel!, error: Swift.Error!) {
        print("Anything")
    }
}

期望的回调处理逻辑

func activator(_ activator: TuyaSmartActivator!, didReceiveDevice deviceModel: TuyaSmartDeviceModel!, error: Error!) {
    if deviceModel != nil && error == nil {
        // 设备配对成功，执行后续操作
    }

    if let e = error {
        // 设备配对失败，打印错误信息
        print("\(e)")
    }
}

问题原因及修复方案

问题根源

你在startConfigWiFi方法中创建的tuyaSmartActivatorDelegate是局部变量，方法执行完毕后这个实例会被系统销毁，导致TuyaSmartActivator找不到有效的代理对象，因此无法触发回调方法。

修复步骤

在View中持有代理实例：
在HomeDevices结构体中添加@StateObject属性来保存代理实例，确保它的生命周期和View一致，不会被提前销毁。
调整代理类实现：
修正类名（遵循Swift大驼峰命名规范），并确保代理设置正确。
修改配网启动逻辑：
直接使用持有的代理对象启动配网，不再创建局部代理实例。
