iOS中的Asyncsocket斷開連接事件

Question

我正在使用iOS中的Asyncsocket客戶端。

https://github.com/robbiehanson/CocoaAsyncSocket

我怎麼知道什麼時候服務器和客戶端之間的套接字連接壞了？

應使用什麼委託方法來檢測斷開？

謝謝。

Answer 1

你應該閱讀AsyncSocket.h，下面是非常接近頂部（第一回調實際上給你的斷線的原因的信息，其可以有用）

/** 
* 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;

看來，您使用的委託方法：

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