当我使用 Apple Scripting Bridge 发送带有附件的消息时，消息的背景设置为黑色，这是一个问题，因为文本也是黑色的。有问题的代码是：

MailApplication *mail = [SBApplication applicationWithBundleIdentifier:@"com.apple.Mail"];

/* create a new outgoing message object */
MailOutgoingMessage *emailMessage =
[[[mail classForScriptingClass:@"outgoing message"] alloc]
 initWithProperties:
[NSDictionary dictionaryWithObjectsAndKeys:
 emailSubject, @"subject",
 [self composeEmailBody], @"content", nil]];

/* add the object to the mail app  */
[[mail outgoingMessages] addObject: emailMessage];

/* set the sender, show the message */
emailMessage.sender = [NSString stringWithFormat:@"%@ <%@>",[[[mail accounts] objectAtIndex:playerOptions.mailAccount] fullName],[[[[mail accounts] objectAtIndex:playerOptions.mailAccount] emailAddresses] objectAtIndex:0]];
emailMessage.visible = YES;

/* create a new recipient and add it to the recipients list */
MailToRecipient *theRecipient =
[[[mail classForScriptingClass:@"to recipient"] alloc]
 initWithProperties:
 [NSDictionary dictionaryWithObjectsAndKeys:
  opponentEmail, @"address",
  nil]];
[emailMessage.toRecipients addObject: theRecipient];

/* add an attachment, if one was specified */
if ( [playerInfo.gameFile length] > 0 ) {

    /* create an attachment object */
    MailAttachment *theAttachment = [[[mail classForScriptingClass:@"attachment"] alloc] initWithProperties:
                                     [NSDictionary dictionaryWithObjectsAndKeys:
                                      playerInfo.gameFile, @"fileName", nil]];

    /* add it to the list of attachments */
    [[emailMessage.content attachments] addObject: theAttachment];
}
/* send the message */
[emailMessage send];

背景颜色的实际变化发生在倒数第二行，即：

[[emailMessage.content attachments] addObject: theAttachment];

上面的代码部分基本上来自 Apple 的 SBSendMail 示例代码。在这个阶段，我实际上只进行了与应用程序中的数据集成所需的更改。如果我在从 Apple 新下载 SBSendMail 示例后构建并运行它，则消息背景也会更改为黑色并执行同一行。附加的文件类型、位置或使用的计算机或操作系统似乎都无关紧要。

这可能是 Apple 脚本桥中的一个错误，但有没有人遇到过这个问题并找到了解决方案？或者，是否有人知道 MailOutgoingMessage 实例的背景颜色是否可以通过脚本桥接更改？

我不认为问题出在您的代码中。我认为这是最近出现的一个错误。对这个问题的快速谷歌搜索出现了这个：http ://discussions.apple.com/thread.jspa?threadID=2453797&start=0&tstart=0
