Question

我正在尝试将图像包含在从iPad发送的HTML电子邮件正文中。这似乎不可能。我曾尝试使用CID方法，但似乎在iOS中无法获取/设置附件的CID。

我还尝试使用src="data:image/png;base64, blahblahblah"嵌入图片。撰写邮件时，它似乎有效，但收到邮件时没有任何内容。

有什么想法吗？

更多详情：我们不是在寻找在电子邮件底部附加JPEG / PNG的解决方案。使用[composer addAttachmentData:mimeType:fileName:]很容易做到。

我们正在寻找一种解决方案，其中图像嵌入在HTML格式的电子邮件中内嵌。您可以在该IMG标记周围包含一个链接，这样当收件人点击IMG时，他/她将被链接到该应用的iTunes页面。

Answer 1

从github下载NSData+base64类别。

然后执行以下操作：

NSData *imageData = [NSData dataWithContentsOfFile:pathInDocumentDirectory(imagePath)];
NSString *base64String = [imageData base64EncodedString];
NSString *imageString = [NSString stringWithFormat:@"data:image/png;base64,%@", base64String];

最后，将imageString放在HTML主体中您想要显示此图像的位置。

希望它有所帮助！

要在Gmail中显示图片，请执行以下操作：

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

    NSMutableString *emailBody = [[NSMutableString alloc] initWithCapacity:20];

    NSString *linkimg = @"https://idrivethru.com/iDriveThruWeb/faces/javax.faces.resource/idrivethru_logo.png?ln=images";

    //Add the image
    [emailBody appendFormat:@"<p><a href = 'https://idrivethru.com/'> <img src='%@' align='centre' alt='iDriveThru.com'> </a></p><br/>", linkimg];

    [emailBody appendString:@"<p>This is an email with an embeded image right <b>above</b> this text</p>"];

    //NSLog(@"%@",emailBody);

    [mailCont setMessageBody:emailBody isHTML:YES];
    [self presentViewController:mailCont animated:YES completion:nil];
