        console.log("Scan view controller initialized")  

        // 检查 scanVc 是否为 null  
        if (scanVc != null) {  
            const rootVC = UTSiOS.getCurrentViewController()  
            rootVC.present(scanVc, animated = true)  
            console.log(scanVc);  
        } else {  
            console.error("Failed to initialize HmsDefaultScanViewController")  
        }  
    }  

}  
export function scanCode(options : HWcanCodeOptions) {  
    // uts方法默认会在子线程中执行，涉及 UI 操作必须在主线程中运行，通过 DispatchQueue.main.async 方法可将代码在主线程中运行  
    DispatchQueue.main.async(execute = () : void => {  

        // 创建 NativeCode 的实例  
        const nativeCode = new ScanCodeT()  

        // 设置回调函数  
        // nativeCode.scanResultCallback = (result) => {  
        //  console.log("Scan result received in UTS:", result)  
        // }  

        // 调用 scan 方法  
        nativeCode.scan()  
    })  
}

uts插件,iOS端,做的是华为统一扫码的功能,扫码完成之后一直触发不了代理,能帮看下是哪里写的不对吗?

}

Delegate参数类型要正确，建议用swift来做
