ios - 调用InApp邮件命令时应用程序崩溃

Question

当我通过UIActionSheet按钮输入Message Compose表时，我收到以下错误。对不起这些对我来说意义不大 - 还在学习： - ）

有人可以帮忙吗？

这些是出现问题的根源。

这是在日志中：

        mailer.mailComposeDelegate = self;

        NSString *subject = [[NSString alloc] initWithFormat:@"Multi Web - Sending %@.txt", _documentFile];

        [mailer setSubject:subject];

        [mailer setMessageBody:emailBody isHTML:YES];

        [self presentModalViewController:mailer animated:YES];
    }

    // Remove the mail view

    default:
        NSLog(@"Mail not sent.");
        break;
}

// Remove the mail view
[self dismissModalViewControllerAnimated:YES];

}

Answer 1

正确的答案是删除

[self dismissModalViewControllerAnimated:YES] 

就在presentModalViewController方法之后。

你正在崩溃，因为你在模拟视图控制器出现后立即将其解除，并尝试在回调委托中再次解除它（已经解除分配）。
