无法将XMPPFramework连接到iOS中的Openfire服务器 [英] Unable to connect XMPPFramework to Openfire server in iOS

问题描述

我正在使用 iOS 聊天应用，用户登录应用。我已经从GitHub XMPPFramework 下载了 XMPPFramework 。我试图通过 XMPP 框架与 Openfire 服务器.com / tutorials / building-a-jabber-client-for-ios-xmpp-setup - mobile-7190rel =nofollow noreferrer>本教程。这是我将XMPP连接到openfire的代码。

I am working on an iOS chat app where user login to app. I've downloaded XMPPFramework from GitHub XMPPFramework. I am trying to connect XMPP framework with Openfire server by following this tutorial. Here is my code to connect XMPP to openfire.

- (BOOL)connect {

    [self setupStream];
    [xmppStream setHostName:@"192.168.1.5"];
    [xmppStream setHostPort:5222];

    NSString *jabberID = [[NSUserDefaults standardUserDefaults] stringForKey:@"userID"];
    NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"userPassword"];

    if (![xmppStream isDisconnected])
        return YES;

    if (jabberID == nil || myPassword == nil)
        return NO;

    [xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];
    password = myPassword;

    NSError *error = nil;
    if (![xmppStream isConnected])
    {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
                                                            message:[NSString stringWithFormat:@"Can't connect to server %@", [error localizedDescription]]
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];
        return NO;
    }
    return YES;
}

问题是当我运行应用程序时，它会显示警告无法连接到服务器。我已经在StackOverflow上检查了很多问题，并尝试使用谷歌搜索，但找不到任何相关的解决方案。如何将它连接到Openfire服务？如果我在我的代码中做错了什么，请建议我用一段代码或教程来实现这一点。

The problem is when I run the app, it shows the alert can't connect to server. I have checked many questions on StackOverflow and tried googling but couldn't find any relevant solution. How to connect it to the Openfire serve? If I am doing anything wrong in my code please suggest me with a snippet of code or a tutorial to make this happen.

推荐答案

希望这仍然相关，如果没有，希望它会帮助别人。
您的代码存在一些问题：

Hope this still relevant, if not, hopefully it will help others. There are some issues with your code:

1. 我没有看到连接的调用，你应该添加这样的事情：

1. I don't see the call to connect, you should add something like this:

NSError *error = nil;
if (![_xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) { 
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error connecting"
                                                        message:@"Msg"
                                                       delegate:nil
                                              cancelButtonTitle:@"Ok"
                                              otherButtonTitles:nil];
    [alertView show];       
}

大多数XMPP API都是异步的。

您必须设置流委托才能接收事件。
查看 XMPPStreamDelegate 和 XMPPStream＃addDelegate

如果您不想自己查看代码 XMPPStream.h
，您可以实现 XMPPStreamDelegate 的所有方法并记录事件。这将有助于您了解框架的工作原理。

If you don't want to go through the code yourself XMPPStream.h , you can implement all methods of XMPPStreamDelegate and log the events. This will help you understand how the framework works.
