Macos 通过沙盒发送带有脚本桥的邮件附件

在10.6和10.7中，我一直在使用脚本桥让邮件发送带有附件的邮件，但表单10.8邮件应用程序本身是沙盒，因此无法访问附件文件

MailApplication *mail = [SBApplication applicationWithBundleIdentifier:@"com.apple.Mail"];
MailOutgoingMessage *mailMessage = [[[mail classForScriptingClass:@"outgoing message"] alloc] initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:subject, @"subject",body, @"content", nil]];
[[mail outgoingMessages] addObject:mailMessage];
[mailMessage setVisible:YES];
for (NSString *eachPath in paths) {
    if ( [eachPath length] > 0 ) {
        MailAttachment *theAttachment = [[[mail classForScriptingClass:@"attachment"] alloc] initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:eachPath, @"fileName",nil]];
        [[mailMessage.content attachments] addObject: theAttachment];
    }
}
[mail activate];

我读到一条建议，看看iCal使用AppleScript打开带有附件的邮件的方式：

on send_mail_sbp(subjectLine, messageText, invitationPath)
    set pfile to POSIX file invitationPath
    set myfile to pfile as alias
    tell application "Mail"
        set mymail to (make new outgoing message at the beginning of outgoing messages with properties {subject:subjectLine, content:messageText})
        tell mymail
            tell content
                make new attachment with properties {file name:myfile} at after the last word of the the last paragraph
            end tell
        end tell
        set visible of mymail to true
        activate
    end tell
end send_mail_sbp

从applescript来看，我似乎需要在附件路径（在我的情况下是临时文件）中使用别名，而不是现在使用的无法通过邮件访问的路径。

是否有一种简单的方法可以使用脚本brige添加此步骤？

找到了解决方案：要在Mountain Lion中使用沙箱，您必须提供附件的NSURL，而不是作为NSString的文件路径

MailAttachment *theAttachment = [[[mail classForScriptingClass:@"attachment"] alloc] initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:[NSURL fileURLWithPath:eachPath], @"fileName",nil]];

（这也适用于Lion，但在Snow Leopard中，必须将文件路径用作NSString）
