iPhone TCP/IP套接字服务器/客户端程序

this tutorial 创建一个聊天示例应用程序工作得非常好,非常简单(任何iphone noob,像我一样,都可以让它工作,即使在模拟器模式下,它连接到外部套接字服务器)。

我把它改装成了我的socket服务器,它工作起来很有魅力。这是测试代码,所以没有真正的问题。它只发送一条消息(您的登录id)并收到回复,该回复显示在控制台中。

您的ViewController.h文件将包含

- (IBAction)joinChat:(id)sender;


@end
NSInputStream *inputStream;
NSOutputStream *outputStream;
NSMutableArray * messages;

NOOBS ONLY 2:此套接字将在XCODE的控制台窗格中输出。在xcode窗口的右上角,单击隐藏或显示调试区域(如有必要,请寻求帮助)。

在带有2GB内存的macbook上构建并测试(模拟器和设备),使用雪豹xcode 4.2。

Cocoa Async Socket

网站上还有一个基本的示例项目可以帮助您开始。我在使用该框架方面取得了很大的成功。
