ios - 带有 Objective-C 客户端的 Socket.IO-Swift 库

Question

我正在为我的 iOS 聊天应用程序使用 Socket.IO。聊天库调用socket.io-client-swift在 Swift 中，我可以设法使用桥接将它手动集成到我的 Objective-C 项目中。

我将“Source”文件夹从上面的库导入到我的 Xcode 中，并使用以下代码将 #import "MyProjectName-Swift.h"放入我的 ChatViewController 中:

//in viewDidLoad
NSURL* url = [[NSURL alloc] initWithString:@"http://localhost:3000/"];
SocketIOClient* socket = [[SocketIOClient alloc] initWithSocketURL:url options:@{@"log": @YES, @"forcePolling": @YES}];

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

[socket on:@"currentAmount" callback:^(NSArray* data, SocketAckEmitter* ack) {
double cur = [[data objectAtIndex:0] floatValue];

[socket emitWithAck:@"canUpdate" withItems:@[@(cur)]](0, ^(NSArray* data) {
    [socket emit:@"update" withItems:@[@{@"amount": @(cur + 2.50)}]];
});

[ack with:@[@"Got your currentAmount, ", @"dude"]];
}];

[socket connect];

在 http://localhost:3000/ 的帮助下，我在本地使用 node.js(this tutorial)从中发送消息，我可以在我的 Xcode 控制台中同时看到它:

2016-05-13 14:59:24.035 CoreData_Chat[45303:373285] LOG SocketIOClient: Handling event: chat message with data: (
hii)

那么，我如何发出此消息以显示在我的应用程序中和/或将消息发送到服务器。没有任何明确的教程解释这一点，尤其是在 Objective-C 中。谁能帮忙？谢谢。

NSMutableDictionary *messageServer = [[NSMutableDictionary alloc]init];
[messageServer setObject:@"bet" forKey:userActivity];
[messageServer setObject:@"0" forKey:betMoney];
SocketIOClient emit:EVENTNAME withItems:@[messageServer];
