ios下关于uts插件回调函数问题

我在IOS下开发UTS插件，需要用到线程回调函数，完全按照官方例子，运行时报错提示如下：
Error in event handler for "api.onSocketTaskStateChange": "Error: method call failed: -[NSThread initWithTarget:selector:object:]: target does not implement selector ( -[UTSSDKModulesMindtopUdpUDPServerByJs recv])"[ERROR] : [Vue warn]: Error in event handler for "api.onSocketTaskStateChange": "Error: method call failed: -[NSThread initWithTarget:selector:object:]: target does not implement selector ( -[UTSSDKModulesMindtopUdpUDPServerByJs recv])"(found <Root>) __ERROR

我的代码如下：

const method=Selector("recv");
console.log(method)
this.nsthread = new Thread(target=self, selector=method , object=null);
this.nsthread?.start();

这段是打开线程的代码

我的线程回调函数为：

@objc static recv() {
console.log("asdad")
/server.isListener = true;
while (true) {
if (!server.isListener) return
try {
let ret = server.server.recv(8192);
console.log(ret)
} catch (e) {
error?.(e)
server.isListener = false
}
}/
console.log("fffff");
}
