        message,kSKPSMTPPartMessageKey,kSKPSMTPPartContentTransferEncodingKey, nil];

//    NSDictionary *plainPart =  @{

    [NSString stringWithFormat:@"%@",message];

    NSLog(@"\r\r\rAbout to send\r\r\r");

    [smtpTestMessage send];
    NSLog(@"sent");
}

每当我运行它时，我都会按下“发送”按钮，电子邮件几乎会发送，直到我遇到这个：

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-     [__NSCFString appendString:]: nil argument'

我觉得好像我已经尝试了一切。我为如此直率而道歉，但我已经为此困扰了一段时间！老实说，我已经准备好放弃了。预先感谢您的任何帮助！谢谢你甚至看这篇文章！xD <3

好的。所以 smtpTestMessage.parts 归零。它被设置为 NSArray。如何将 NSString“消息”放入 NSArray 以用于 smtpTestMessage.parts？解决此问题后，应用程序应该可以工作。

老实说，如果我可以把任何东西放在 smtpTestMessage.parts 中，它应该可以工作。只要它不回来为零。

在调试器中创建异常断点 ( https://developer.apple.com/library/ios/recipes/xcode_help-breakpoint_navigator/articles/adding_an_exception_breakpoint.html )。打破它，然后发布回溯。

这是任何人都可以根据所提供的证据给出的答案。
