1.pod 下载RACSRWebSocket

2.添加包

Security.framework

Foundation.framework

CFNetwork.framework

libicucore.A.tbd

libicucore.tbd

3.创建单利

导入#import <SocketRocket/SRWebSocket.h>

.h中的方法

.m中的具体实现

首先是 socket必须实现的代理方法 

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

NSLog(@"WebSocket DidOpen");

[webSocket send:jsonString];//打开socket后根据后端要求传入字典字符串

}

-(void)webSocket:(SRWebSocket *)webSocket didReceiveMessage:(id)message{

//socket接收到信息后通过代理传给外部使用

[self.delegate getMessageFromSocket:dic];

}

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

NSLog(@"WebSocket closed");

}

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

NSLog(@":( Websocket Failed With Error %@", error);

}

下面是几个供外部调用的方法

//因为URL不可能是死的需要从接口中获取,所以这个方法用于在接口中拿到URL

- (void)WithIP:(NSString *)URLIP{

_webSocket.delegate = nil;

[_webSocket close];

NSString *urlStr = [NSString stringWithFormat:@"%@", URLIP];

NSURL *url = [NSURL URLWithString:urlStr];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];

//如需更改链接的头部则需此步

[request setValue:@"http://xxxxxx" forHTTPHeaderField:@"xxx"];

_webSocket = [[SRWebSocket alloc] initWithURLRequest:request];

_webSocket.delegate = self;

}

//拿到URL后可以打开webSocket

- (void)openSocket {

[_webSocket open];

}

//退出页面时记得关闭webSocket

- (void)closeSocket {

self.webSocket.delegate = nil;

[self.webSocket close];

self.webSocket = nil;

}

//外部聊天发送消息给webSocket

- (void)sendTalkMessage:(NSString *)message{

NSMutableDictionary *dic = [NSMutableDictionary dictionary];

dic = [@{ @"content":message} mutableCopy];

[self sendMessage:dic];

}

4.在ViewController中调用

导入#import "webSocketManager.h"

创建单利

@property (nonatomic, strong) webSocketManager *webSocket;

下面是几个主要的方法使用
