cocoa - 使用脚本桥创建邮件

Question

我正在尝试使用 cocoa 脚本桥创建一封新电子邮件，但似乎无法让它工作。到目前为止我已经:

MailApplication *mail = [SBApplication applicationWithBundleIdentifier:@"com.apple.Mail"];
MailOutgoingMessage *emailMessage = [[[[mail classForScriptingClass:@"outgoing message"]     alloc] initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys: [saveFileName substringToIndex:[saveFileName length]-4], @"subject", @"something about app.", @"content", nil]] autorelease];
// add the object to the mail app 
[[mail outgoingMessages] addObject: emailMessage];
emailMessage.visible = YES;

if ( [FileFullName length] > 0 ) {

    MailAttachment *theAttachment = 
    [[[mail classForScriptingClass:@"attachment"] alloc]
     initWithProperties:[NSDictionary dictionaryWithObjectsAndKeys:
                         FileFullName, @"fileName",nil]];
    // add it to the list of attachments 
    [[emailMessage.content attachments] addObject: theAttachment];
    [theAttachment release];
}

当我尝试设置可见属性时，我收到错误消息:

-[SBProxyByClass setVisible:]: object has not been added to a container yet; selector not recognized [self = 0x7fd4fae3cc90]

当我为应用程序添加沙箱时出现此问题。谁能指出正确的方向吗？

Answer 1

如果您的代码可以在启用沙箱之前运行，那么您应该在发送邮件之前先执行此操作。将以下代码添加到您的 Entitlements.plist 中。

    <key>com.apple.security.temporary-exception.apple-events</key>
    <array>
    <string>com.apple.mail</string>
    </array>
