Question

我在我的iOS聊天应用程序中使用Socket.IO。名为socket.io-client-swift的聊天库位于Swift中，我可以设法使用桥接手动将其集成到我的Objective-C项目中。

我导入了＆＃39;来源＆＃39;从库上面的文件夹到我的Xcode并放置#import＆＃34; MyProjectName-Swift.h＆＃34;在我的ChatViewController中，代码如下：

//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];

我在http://localhost:3000/的帮助下在本地（this tutorial）使用node.js来发送消息，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/或向服务器发送消息。没有任何明确的教程解释这一点，特别是在Objective-C中。有人可以帮忙吗？谢谢。

Answer 1

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

带有Objective-C Client的Socket.IO-Swift库
