如何从XMPP/OpenFire检索iOS中的vCard [英] How to retrieve vCard in iOS from XMPP/OpenFire

问题描述

顾名思义，我正在尝试使用以下XMPPFrameworks方法之一为用户检索电子名片:

As the name suggests I am trying to retrieve a vCard for a user using one of the next XMPPFrameworks methods:

- (XMPPvCardTemp *)fetchvCardTempForJID:(XMPPJID *)jid;
- (XMPPvCardTemp *)fetchvCardTempForJID:(XMPPJID *)jid useCache:(BOOL)useCache;

我当前的实现是:

dispatch_queue_t queue = dispatch_queue_create("queue", DISPATCH_QUEUE_PRIORITY_DEFAULT);
dispatch_async(queue, ^{

    XMPPvCardCoreDataStorage* xmppvCardStorage = [XMPPvCardCoreDataStorage sharedInstance];
    XMPPvCardTempModule* m = [[XMPPvCardTempModule alloc] initWithvCardStorage:xmppvCardStorage];
    [m fetchvCardTempForJID:[sender myJID] ignoreStorage:YES];
    NSLog(@"%@",xmppvCardStorage.description);
                       });

上面的代码不起作用，如果当前的方法正确，我也想知道如何记录数据.

The code above is not working and also I wanted to know how can I log the data, if the current approach is the right one.

推荐答案

首先创建appdelegate的实例:

First create a instance of the appdelegate:

-(AppDelegate *) appDelegate{
return (AppDelegate *)[UIApplication sharedApplication].delegate;}

然后使用以下代码检索电子名片:

Then use below code to retrieve the vCard:

XMPPvCardTemp *vCard =[[self appDelegate].xmppvCardTempModule vCardTempForJID:[self appDelegate].xmppStream.myJID.bareJID shouldFetch:YES];

这里我使用了当前用户的JID.您可以使用其他用户的JID，但请确保它应该是XMPPJID对象.

Here I have used the current user JID. You can used other users JID, but make sure that it should be a XMPPJID object.

使用XMPPvCardTemp对象记录它

Log it using the object of the XMPPvCardTemp

NSLog(@"%@", vCard.nickname);
NSLog(@"%@", vCard.name);
NSLog(@"%@", vCard.emailAddresses);
NSLog(@"%@", vCard.formattedName);
NSLog(@"%@", vCard.givenName);
NSLog(@"%@", vCard.middleName);
