接 CocoaAsyncSocket 學(xué)習(xí) （一）

實(shí)現(xiàn)自動(dòng)邏輯回復(fù)功能

• 在 監(jiān)聽接入客戶端的方法中 監(jiān)聽到接入后 寫入客戶端數(shù)據(jù)

- (void)socket:(GCDAsyncSocket *)sock didAcceptNewSocket:(GCDAsyncSocket *)newSocket {
    NSLog(@"服務(wù)端  %@", sock);
    NSLog(@"客戶端  %@", newSocket);
    [self.clientSockets addObject:newSocket];
    
    
    NSMutableString *mutableStr = [NSMutableString string];
    [mutableStr appendString:@"歡迎來到10086在線服務(wù)，請輸入下面的數(shù)字選擇服務(wù)\n"];
    [mutableStr appendString:@"[0]在線充值\n"];
    [mutableStr appendString:@"[1]在線投訴\n"];
    [mutableStr appendString:@"[2]優(yōu)惠信息\n"];
    [mutableStr appendString:@"[3]special services\n"];
    
    [newSocket writeData:[mutableStr dataUsingEncoding:NSUTF8StringEncoding] withTimeout:-1 tag:0];
    
    // 監(jiān)聽客戶端是否寫入數(shù)據(jù)
    // timeOut: -1 暫時(shí)不需要 超時(shí)時(shí)間  tag暫時(shí)不需要 傳0
    [newSocket readDataWithTimeout:-1 tag:0];
}

- (void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag {
    
    NSLog(@"客戶端  %@", sock);
    NSString *dataStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"data --- %@", dataStr);
    
    
    NSInteger index = [dataStr integerValue];
    NSString *responseStr = nil;
    switch (index) {
        case 0:
            responseStr = @"充值服務(wù)暫停中...\n";
            break;
        case 1:
            responseStr = @"投訴服務(wù)暫停中...\n";
            break;
        case 2:
            responseStr = @"優(yōu)惠信息沒有...\n";
            break;
        case 3:
            responseStr = @"SB 怎么可能有特殊服務(wù)...\n";
            break;
        case 4:
            responseStr = @"退出成功...\n";
            break; 
      
        default:
            responseStr = @"指令無效...\n";
            break;
    }
    
#####退出連接的話  將客戶端socket 從數(shù)組中移除即可
      if (index == 4) {
        [self.clientSockets removeObject:sock];
    }
    // 服務(wù)端接收到客戶端發(fā)送的數(shù)據(jù)之后  返回?cái)?shù)據(jù)給 客戶端
    // 我們將接受到的數(shù)據(jù)返回回去
    [sock writeData:[responseStr dataUsingEncoding:NSUTF8StringEncoding] withTimeout:-1 tag:0];
    
    [sock readDataWithTimeout:-1 tag:0];
}
