如标题所示，我正在尝试从服务器上为用户获取vCard，但似乎不起作用，有什么主意吗？我将不胜感激
这是我的代码以及流连接和身份验证，我也包括了这一部分，因为它们也可能有问题，因为我是使用XMPP Framework的菜鸟，我使用的iOS客户端是:https://github.com/robbiehanson/XMPPFramework
.h类代码为:
#import <UIKit/UIKit.h>
#import "XMPPStream.h"
#import "XMPP.h"
#import "XMPPReconnect.h"
#import "XMPPPresence.h"
#import "XMPPRoster.h"
#import "ForgotPasswordViewController.h"
#import "XMPPReconnect.h"
#import "XMPPRosterCoreDataStorage.h"
#import "ConractsViewController.h"
#import "KeychainItemWrapper.h"
#import "SignUpViewController.h"
#import "XMPPvCardTemp.h"

[xmppvCardTempModule activate:xmppStream];
[xmppvCardTempModule addDelegate:self delegateQueue:dispatch_get_main_queue()];
reconnect = [[XMPPReconnect alloc] init];
[reconnect activate:xmppStream];
NSError *error = nil;
if (![xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
NSLog(@"error: %@", error);
}
NSLog(@"error: %@", error);
}
- (void)xmppStreamDidConnect:(XMPPStream *)sender {
NSError *error = nil;
if (![xmppStream authenticateWithPassword:@"test" error:&error]) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error"
message:[NSString stringWithFormat:@"Can't authenticate %@", [error localizedDescription]]
delegate:nil
cancelButtonTitle:@"Ok"
otherButtonTitles:nil];
[alertView show];
}
XMPPPresence *mypresence = [XMPPPresence presenceWithType:@"available"];
[xmppStream sendElement:mypresence];
}
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender{
NSLog(@"e%d",[xmppStream isConnected]);//prints out 1
NSLog(@"e%d",[xmppStream isAuthenticated]);//prints out 1
if ([xmppStream isAuthenticated]) {
NSLog(@"authenticated");
[xmppvCardTempModule fetchvCardTempForJID:[XMPPJID jidWithString:@"test11@administrator"] ignoreStorage:YES];
}
}
- (void)xmppvCardTempModule:(XMPPvCardTempModule *)vCardTempModule
didReceivevCardTemp:(XMPPvCardTemp *)vCardTemp
forJID:(XMPPJID *)jid{
XMPPvCardTemp *test = [xmppvCardStorage vCardTempForJID:jid xmppStream:xmppStream];
NSLog(@"Stored card: %@",test.description);
//Prints out: "Stored card: (null)"
}
当我连接并进行身份验证但未提取卡时，它返回1，这至少部分正确吗？

How to create/ update/ retrieve user vCard using XMPPFramework and OpeFire on iOS
最佳答案
您可以使用[AppDelegate delegate].xmppvCardTempModule myvCardTemp]获取登录的用户vCard。如果您使用的是https://github.com/robbiehanson/XMPPFramework，则此代码。
如果要更新vCard，可以在您的appdelegate中使用此代码
- (void)updateProfile:(UIImage *)profilePicture userData:(NSDictionary *)userData
{
NSMutableArray *elements = [NSMutableArray array];
[elements addObject:[NSXMLElement elementWithName:@"fullname" stringValue:@""]];
NSData *pictureData = UIImagePNGRepresentation(profilePicture);
dispatch_queue_t queue = dispatch_queue_create("queue", DISPATCH_QUEUE_PRIORITY_DEFAULT);
dispatch_async(queue, ^{
XMPPvCardTemp *myVcardTemp = [xmppvCardTempModule myvCardTemp];
[myVcardTemp setPhoto:pictureData];
[myVcardTemp setEmailAddresses:@[[userData valueForKey:@"email"]]];
[myVcardTemp setName:[userData valueForKey:@"name"]];
[xmppvCardTempModule updateMyvCardTemp:myVcardTemp];
});
}
更新
- (void)configurePhotoForCell:(CurrentChatCell *)cell user:(XMPPUserCoreDataStorageObject *)user
{
// Our xmppRosterStorage will cache photos as they arrive from the xmppvCardAvatarModule.
// We only need to ask the avatar module for a photo, if the roster doesn't have it.
if (user.photo != nil)
{
cell.imgUser.image = user.photo;
}
else
{
NSData *photoData = [[[AppDelegate delegate] xmppvCardAvatarModule] photoDataForJID:user.jid];
if (photoData != nil)
cell.imgUser.image = [UIImage imageWithData:photoData];
else
cell.imgUser.image = [UIImage imageNamed:@"userUnknown"]; //Setting a demo image only }
}
我从cell_for_row_at_index调用此方法，您可以在此处发送用户数据。
