iOS集成涂鸦Smart Life SDK启动触发NSException崩溃求助

问题背景 #

我是iOS开发新手，正在尝试用涂鸦Smart Life App SDK开发IoT应用。根据快速集成指南，SDK初始化代码需要放在AppDelegate.m中，但Xcode 14.3.1不会自动生成该文件，于是我在AppNameApp.swift中添加了AppDelegate类，代码如下：

import SwiftUI
import ThingSmartBaseKit

@main
struct AppNameApp: App {
    
    @UIApplicationDelegateAdaptor(AppDelegate.self) var appDelegate
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        ThingSmartSDK.sharedInstance().start(withAppKey: <#your_app_key#>, secretKey: <#your_secret_key#>)
        
        #if DEBUG
        ThingSmartSDK.sharedInstance().debugMode = true
        #else
        #endif
        
        return true
    }
}

Xcode中未显示任何报错，但在模拟器上运行应用时，因未捕获的NSException类型异常崩溃，崩溃信息如下：

问题原因及解决方法 #

崩溃提示NSArray找不到yy_modelArrayWithClass:json:方法，说明涂鸦SDK依赖的YYModel库未正确引入或链接，按以下步骤排查：

• 检查CocoaPods依赖：如果用CocoaPods集成SDK，确认Podfile包含完整的涂鸦SDK依赖，执行pod install更新依赖。涂鸦SDK通常会自动引入YYModel，若Podfile未正确配置，需补充相关依赖。
• 手动集成补全依赖：如果是手动集成SDK，需下载YYModel源码或二进制库，添加到项目中，并在Build Phases > Link Binary With Libraries里添加对应库文件。
• 配置Linker Flags：在项目Build Settings > Other Linker Flags中添加-ObjC，因为YYModel基于Category扩展，需要该标志才能正常加载Category方法。
• 清理重建项目：执行Cmd+Shift+K清理项目缓存，再用Cmd+B重新构建，避免缓存导致的链接异常。
• 更新SDK版本：确认使用的是涂鸦最新版SDK，旧版本可能存在SwiftUI项目的兼容问题，替换为最新版本尝试。
