使用MFMailComposeViewController类从iPhone App发送带有IMG标签的HTML电子邮件

我正在使用MFMailComposeViewController类从我的iPhone应用程序发送格式化的HTML电子邮件.我需要在电子邮件中包含一个图像,我将IMG标记添加到我的电子邮件中

- (IBAction)shareWithOther
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;

    [picker setSubject:@"My Message Subject"];

    NSString *emailBody = @"<h3>Some and follow by an image</h3><img src=\"SG10002_1.jpg\"/>and then more text.";
    [picker setMessageBody:emailBody isHTML:YES];

    [self presentModalViewController:picker animated:YES];
    [picker release];
}

图像文件,"SG10002_1.jpg"添加到我的资源文件夹,但图像没有在邮件正文中显示(只显示为[？]).有人可以告诉我我做错了什么,比如图像的路径是错误的还是有更好的方法来做到这一点？

非常感谢.

我坚信(根据您的问题)您的图片SG10002_1.jpg位于主要包中.
如果是这样,那么下面的代码应该适合你.这是一个完全破解这个问题.

- (void)createEmail {
//Create a string with HTML formatting for the email body
    NSMutableString *emailBody = [[[NSMutableString alloc] initWithString:@"<html><body>"] retain];
 //Add some text to it however you want
    [emailBody appendString:@"<p>Some email body text can go here</p>"];
 //Pick an image to insert
 //This example would come from the main bundle, but your source can be elsewhere
    UIImage *emailImage = [UIImage imageNamed:@"myImageName.png"];
 //Convert the image into data
    NSData *imageData = [NSData dataWithData:UIImagePNGRepresentation(emailImage)];
 //Create a base64 string representation of the data using NSData+Base64
    NSString *base64String = [imageData base64EncodedString];
 //Add the encoded string to the emailBody string
 //Don't forget the "<b>" tags are required, the "<p>" tags are optional
    [emailBody appendString:[NSString stringWithFormat:@"<p><b><img src='data:image/png;base64,%@'></b></p>",base64String]];
 //You could repeat here with more text or images, otherwise
 //close the HTML formatting
    [emailBody appendString:@"</body></html>"];
    NSLog(@"%@",emailBody);

 //Create the 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];
}
