iOS中的Asyncsocket断开连接事件

Question

我正在使用iOS中的Asyncsocket客户端。

https://github.com/robbiehanson/CocoaAsyncSocket

如何知道服务器和客户端之间的套接字连接何时中断？

我应该使用什么委托方法来检测断开连接？

感谢。

Answer 1

您应该阅读AsyncSocket.h，以下内容非常靠近顶部（第一个回调实际上会为您提供有关断开连接原因的信息，这可能很有用）

/**
 * In the event of an error, the socket is closed.
 * You may call "unreadData" during this call-back to get the last bit of data off the socket.
 * When connecting, this delegate method may be called
 * before"onSocket:didAcceptNewSocket:" or "onSocket:didConnectToHost:".
**/
- (void)onSocket:(AsyncSocket *)sock willDisconnectWithError:(NSError *)err;

/**
 * Called when a socket disconnects with or without error.  If you want to release a socket after it disconnects,
 * do so here. It is not safe to do that during "onSocket:willDisconnectWithError:".
 * 
 * If you call the disconnect method, and the socket wasn't already disconnected,
 * this delegate method will be called before the disconnect method returns.
**/
- (void)onSocketDidDisconnect:(AsyncSocket *)sock;

Answer 2

您似乎使用委托方法：

- (void)onSocketDidDisconnect:(AsyncSocket *)sock;
