有没有人有关于从 iPhone SDK 发送 UDP 数据包的好教程?

Does anyone have any good tutorials on sending UDP packets from the iPhone SDK?

其实真的很容易做到这一点...

Was actually really easy to do this...

RTFM！

在包含 AsyncUdpSocket 之后，只需在 header 中添加:

After including AsyncUdpSocket just add this in header:

AsyncUdpSocket *socket;

主要是:

NSData *data = ... 
[socket sendData:data toHost:@"192.168.x.x" port:5002 withTimeout:-1 tag:1];

测试时不要忘记在您的服务器防火墙上允许 UDP 通信！

When testing don't forget to allow UDP communication on your server firewall!

推荐答案

CocoaAsyncSocket 是一个不错的库，它包含一个名为 AsyncUdpSocket 的类，它是一个围绕低级套接字 API 的 Obj-C 包装器.

CocoaAsyncSocket is a nice library that contains a class called AsyncUdpSocket which is an Obj-C wrapper around the lower-level socket API.
