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
