添加额外的标签，例如

<attachment>base64 of your image </attachment>

“Thus send your image”，将其转换为 base64 字符串，然后在接收端将其转换回图像。

只需将 Uiimage 转换为 Base64 编码，然后通过 xmpp 将其作为带有任何额外标签（如附件）的消息发送。然后在接收方获取包含 Base64 内容的消息并将 Base64 编码的字符串转换回 UIImage
编码和解码的代码在此链接中：

...请参考它..如果您有任何疑问或者您想要一个简短的解释，只需在这里评论我会回复它..

Add an extra tag such as

<attachment>base64 of your image </attachment>

Thus sent your image in the sender side by converting it to base64 string and convert the base64 string back into image in the receiver side.

Just convert the Uiimage into a base64encoded coding and then sent it through xmpp as a message with any extra tag like attachement.. Then in the receiver side get the message with the base64 content and convert back the base64encoded string into UIImage
The code for encode and decode is in this link :

... Just refer it.. If you have any doubt or you want a brief explanation, just comment here i will respond to it..

    NSData *data = UIImageJPEGRepresentation(chosenImage, 1.0);

    Base64Transcoder *base64 = [[Base64Transcoder alloc] init];
    NSString *imgStr = [base64 base64EncodedStringfromData:data];


    NSXMLElement *ImgAttachement = [NSXMLElement elementWithName:@"attachment"];
    [ImgAttachement setStringValue:imgStr];
     NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
   [body setStringValue:@"image test"];


    NSXMLElement *message = [NSXMLElement elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:@"[email protected]"];// [NSString stringWithFormat:@"%@@192.168.1.193",self.jabber_id]];

    [message addChild:message];
    [message addChild:ImgAttachement];

     [[[PDAppDelegate sharedDelegate] xmppStream]sendElement:message];

    NSData *data = UIImageJPEGRepresentation(chosenImage, 1.0);
