所以我对这门课有一个严重的问题......

目前，当用户实际发送电子邮件时，ActivityIndi​​cator 显示...太棒了！！！以及 UI 没有被冻结......那太酷了！

问题是，如果用户推送到另一个实际上关闭发送电子邮件视图控制器的视图控制器，应用程序崩溃......我注意到我必须等到第二个“ *** stopping watchdog ***”字符串被记录......以及这个“ S: 221 2.0.0 closing connection i16sm31117760pag.18 - gsmtp”

这是完整的日志，

现在，我“非常快”退出发送电子邮件的视图并继续发送电子邮件，然后我收到此消息*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType messageSent:]: unrecognized selector sent to instance 0xa0a8e50'

当我使用时会发生这种情况[testMsg performSelectorOnBackgroundThread:@selector(send) withObject:nil];

但是当我使用时，[testMsg performSelectorOnMainThread:@selector(send) withObject:nil waitUntilDone:YES];我遇到了与首先发布的日志语句相同的问题......

对不起我可怕的措辞，但我对这个错误有点沮丧:(。

我猜这个错误不在于通过 SMTP 发送邮件。似乎委托对象在 messageSent: 委托方法被调用之前已被释放。

我的建议是在 Application Delegate 中执行 SKPSMTPMessage 发送操作。如果您不希望 SMTP 消息发送句柄位于应用程序委托中，请保留您的委托对象，直到发送邮件或将 SKSMTPMessage 的委托设置为 nil，此时委托对象正在被释放。

希望能帮助到你
