iphone - 如何在电子邮件正文中的某些文本之后设置第一个图像？

转载作者：行者123 更新时间：2023-12-03 20:28:07

我正在使用 MFMailComposeViewController 发送电子邮件，

使用此代码我可以获得图像，但图像位于文本详细信息之后，我不需要第一个图像和之后的文本，

这是我的代码，

   MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
    mail.mailComposeDelegate = self;

    if ([MFMailComposeViewController canSendMail]) {
        //Setting up the Subject, recipients, and message body.
        [mail setToRecipients:[NSArray arrayWithObjects:Emailid,nil]];
        [mail setSubject:@"Receipt"];

        NSData *photoData = UIImageJPEGRepresentation([UIImage imageNamed:@"Gift.png"], 1);
        [mail addAttachmentData:photoData mimeType:@"image/jpg" fileName:[NSString stringWithFormat:@"photo.png"]];

        [mail setMessageBody:@"Receipt" isHTML:NO];
        NSString *emailBody;




        emailBody = [NSString stringWithFormat:@
                     "<br>Purchase Amount:            </br> "      "$  %@"
                     "<br>Amount Received:        </br> "      "$  %@"
                     "<br>Change:    </br> "      "$  %@"
                     ,AmountData,txtAmount.text,ChangeAmount.text];  


        [mail setMessageBody:emailBody isHTML:YES];

请有人建议我我该怎么做？

最佳答案

据我所知，这是 mfmailcomposeviewcontroller 的默认行为，而不是仅仅将图像添加为附件，您可以按如下方式首先显示图像以创建正文部分

(void)createEmail {


NSMutableString *emailBody = [[[NSMutableString alloc] initWithString:@"<html><body>"] retain];
   [emailBody appendString:@"<p>Some email body text can go here</p>"];
   UIImage *emailImage = [UIImage imageNamed:@"myImageName.png"];
   NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(emailImage)];

   NSString *base64String = [imageData base64EncodedString];
  [emailBody appendString:[NSString stringWithFormat:@"<p><b><img src='data:image/png;base64,%@'></b></p>",base64String]];
  [emailBody appendString:@"</body></html>"];
    NSLog(@"%@",emailBody);

 //mail composer window
    MFMailComposeViewController *emailDialog = [[MFMailComposeViewController alloc] init];
    emailDialog.mailComposeDelegate = self;
    [emailDialog setSubject:@"My Inline Image Document"];
    [emailDialog setMessageBody:emailBody isHTML:YES];

    [self presentModalViewController:emailDialog animated:YES];
    [emailDialog release];
    [emailBody release];
}
