Question

我正在使用Socket.IO-Client-Swift＆＃39; -13.2.0＆＃39;在Objective-C中实现我的项目。我尝试使用Socket.IO连接到Node.js服务，并遵循Objective-C的文档。但是当我尝试运行我的代码时，控制台记录并尝试在引擎未打开时连接套接字＆＃39;并且无法通过。

以下是我的代码，

@import SocketIO;
NSURL* url = [[NSURL alloc] initWithString:@"http://URL_STRING:PORT_NUMBER"];

SocketManager *manager = [[SocketManager alloc] initWithSocketURL:url config:@{@"log":@yES, @"compress":@yES}];
SocketIOClient *socket = [manager defaultSocket];

[socket on:@"connect" callback:^(NSArray* data, SocketAckEmitter* ack) {
NSLog(@"socket connected");
}];

[socket connect];

和控制台，

如何解决这个问题？感谢。

Answer 1

已解决：

将经理设置为强。

model.R1 = Param(model.D_S, initialize = R)

Answer 2

SocketIOClient *socket = [manager socketForNamespace:@"/"];

添加此行，它将

代替

SocketIOClient *socket = [manager defaultSocket];

Objective-C：无法使用Socket.IO连接到服务器
