objective-c - 用于发送电子邮件的脚本桥 - 错误 : Object not added to container yet

Question

我们正在使用 SBSendEmail Apple 代码来创建要通过电子邮件应用程序发送的电子邮件。

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

mail.delegate = self;

MailOutgoingMessage *emailMessage = [[[mail    classForScriptingClass:@"outgoing message"] alloc] initWithProperties:
[NSDictionary dictionaryWithObjectsAndKeys:
[self.subjectField stringValue], @"subject",
[[self.messageContent textStorage] string], @"content",
[self.fromField stringValue], @"sender", 
nil]];

[[mail outgoingMessages] addObject: emailMessage];

MailToRecipient *theRecipient = [[[mail classForScriptingClass:@"to recipient"] alloc] initWithProperties:
[NSDictionary dictionaryWithObjectsAndKeys:
[self.toField stringValue], @"address",
nil]];

[emailMessage.toRecipients addObject: theRecipient];
[emailMessage send];

出现此错误:

[General] *** -[SBProxyByCode setSender:]: 对象还没有被添加到容器中；选择器无法识别 [self = 0x600000c85bf0]

如果您能帮助我们解决此问题或提供替代解决方案，我们将不胜感激!

谢谢 约翰

从 Mojave 开始，您需要向用户解释为什么您要求访问 AppleScript。为此，请将其添加到您的 Info.plist 中:

<key>NSAppleEventsUsageDescription</key>
<string>MyApp needs to control ___ because ___</string>

Daniel Jalkut 写道 a good blog post在 Mojave 处于测试阶段时关于此问题。
