XMPPFramework -创建vCard

Question

我在创建vCard时使用了以下代码，但无济于事。它总是放在if块中。有没有人可以检查一下，看看我是不是遗漏了什么？

xmppvCardStorage = [XMPPvCardCoreDataStorage sharedInstance];
xmppvCardTempModule = [[XMPPvCardTempModule alloc] initWithvCardStorage:xmppvCardStorage];
XMPPvCardTemp *myvCardTemp = [xmppvCardTempModule myvCardTemp];

if (!myvCardTemp)
{
    NSXMLElement *vCardXML = [NSXMLElement elementWithName:@"vCard" xmlns:@"vcard-temp"];
    XMPPvCardTemp *newvCardTemp = [XMPPvCardTemp vCardTempFromElement:vCardXML];
    myvCardTemp = newvCardTemp;
}

[myvCardTemp setNickname:@"someNick"];
[myvCardTemp setMiddleName:@"somegender"];
[xmppvCardTempModule updateMyvCardTemp:myvCardTemp];

我已经试过了，但还是不起作用。被调用以获取vcard的函数总是返回nil。

- (XMPPvCardTemp *)vCardTempForJID:(XMPPJID *)jid shouldFetch:(BOOL)shouldFetch

此函数返回nil值。我是不是遗漏了什么？

另一件事是它会向日志中发送一个错误：

Error saving - Error Domain=NSCocoaErrorDomain Code=1570 "The operation couldn’t be completed. (Cocoa error 1570.)

最后，这是我编辑vcard的方法

 -(void)Editvcard
 {
NSMutableDictionary *getdic = [[NSMutableDictionary alloc] init];
getdic = [[NSUserDefaults standardUserDefaults] valueForKey:@"UservCard"];

NSXMLElement *vCardXML = [NSXMLElement elementWithName:@"vCard" xmlns:@"vcard-temp"];
XMPPvCardTemp *newvCardTemp = [XMPPvCardTemp vCardTempFromElement:vCardXML];
//  myvCardTemp = newvCardTemp;
//}
[newvCardTemp setGivenName:[getdic valueForKey:@"username"]];
[newvCardTemp setSortString:[getdic valueForKey:@"status"]];
[newvCardTemp setJid:[XMPPJID jidWithString:[[NSUserDefaults standardUserDefaults] stringForKey:@"kXMPPmyJID"]]];
[newvCardTemp setFormattedName:[getdic valueForKey:@"username"]];
[newvCardTemp setEmailIDnew:[getdic valueForKey:@"emailid"]];    


NSString *img_name = [DatabaseAccess documentsPathForFileName:[getdic valueForKey:@"userimage"]];
NSData *pngData = [NSData dataWithContentsOfFile:img_name];

NSString *strThumb = @"";
if([[[UIDevice currentDevice] systemVersion] floatValue] >=7)
{
    //Encode Image Data
    strThumb = [Base64 encode:pngData];
    //strMapThumb = [pngData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
}
else
{
    //Encode Image Data
    strThumb = [Base64 encode:pngData];
}

[newvCardTemp setPhoto:strThumb];
[xmppvCardTempModule updateMyvCardTemp:newvCardTemp];


}

希望它能帮助你……
