ios 使用websocket ip可以換成域名嗎

開發壹個類似QQ、微信的即時IM聊天功能，做到實時監控消息，需要用的技術是websocket，WebSocket protocol 是HTML5壹種新的協議。它實現了瀏覽器與服務器全雙工通信(full-duplex)。在 WebSocket API，瀏覽器和服務器只需要要做壹個握手的動作，然後，瀏覽器和服務器之間就形成了壹條快速通道。兩者之間就直接可以數據互相傳送。

下面是iOS端我實現websocket通訊，列出步驟思路，以作學習。

1.加入frameworks的 libicucore.dylib

2.導入對象SRWebSocket

3.在聊天的viewController.h引用 #import "SRWebSocket.h"頭文件 SRWebSocketDelegate代理，聲明SRWebSocket *_webSocket;

4.在聊天的viewController.m使用

- (void)connectSocket

{

if (_webSocket ==nil) {

_webSocket = [[SRWebSocketalloc]initWithURLRequest:[NSURLRequestrequestWithURL:[NSURLURLWithString:Web_Socket]]];

_webSocket.delegate =self;

[_webSocket open];

}

}

#pragma mark - SRWebSocketDelegate 寫上具體聊天邏輯

- (void)webSocketDidOpen:(SRWebSocket *)webSocket;

{

// NSLog(@"Websocket Connected");

NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];

[dictionary setValue:@"subscribe" forKey:@"cmd"];

[dictionary setValue:@(VER) forKey:@"ver"];

[dictionary setValue:[settingInfo getSessionId] forKey:@"sid"];

[dictionary setValue:@"1" forKey:@"channel"];

[dictionary setValue:[[settingInfo getUserAccountInfo]objectForKey:@"user_id"] forKey:@"client_id"];

//NSLog(@"dictionary:%@",[dictionary JSONString]);

[_webSocket send:[dictionary JSONString]];

}

......

- (void)webSocket:(SRWebSocket *)webSocket didFailWithError:(NSError *)error

- (void)webSocket:(SRWebSocket *)webSocket didReceiveMessage:(id)message//監控消息

- (void)webSocket:(SRWebSocket *)webSocket didCloseWithCode:(NSInteger)code reason:(NSString *)reason wasClean:(BOOL)wasClean

- (void)webSocket:(SRWebSocket *)webSocket didReceivePong:(NSData *)pongPayload

最後調試，成功，附上壹張效果！
