Question

当发送无效电子邮件时发送电子邮件时，我会在控制台日志中收到“...不是有效的电子邮件地址”。

这没关系，我明白为什么会这样。

我想知道的是......这个NSLog语句来自哪里，我可以访问它吗？

在MFCVController或委托中的某个地方，框架正在检查电子邮件是否有效，然后相应地记录“...不是有效的电子邮件地址”。

我想访问此调用并检查相同的内容并创建alertView。

在评论之前，我已经知道了一些事情...... 我知道如何创建alertViews。我知道并且已经阅读了用户创建的其他帖子，其中包含检查无效电子邮件地址字符串的代码。

感谢您的帮助！

其他信息：

这是一个有用的见解，它确实发生在这里：引用带有吊牌打印输出的NSLog。

        if ([MFMailComposeViewController canSendMail])
    {   NSLog(@"Log 1");

        MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc]init];
        mailer.mailComposeDelegate = self;

        [mailer setSubject:@"Checklist Complete"];
        NSLog(@"Log 2");
        NSArray *toRecipients = [NSArray arrayWithObject:emailAddress];
        NSLog(@"Log 3");
        [mailer setToRecipients:toRecipients];
        NSLog(@"Log 4");
        NSString *emailBody = emailBodyContents;
        NSLog(@"Log 5");
        [mailer setMessageBody:emailBody isHTML:NO];
        NSLog(@"Log 6");
        //For iPad
        //mailer.modalPresentationStyle = UIModalPresentationPageSheet;
        [self presentViewController:mailer animated:YES completion:nil];
        NSLog(@"Log 7");

    }

控制台。

2014-01-15 21:11:30.588 AppTemplate[1018:70b] Log 7

这是我在Xcode中找到的文档

- (void)setToRecipients:(NSArray *)toRecipients __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0)
/*!
@method     setCcRecipients:
@abstract   This method sets the CC header for the email message to the specified email addresses.
@discussion This method will set the CC header for the email message.  This should be called prior to display.
            </p>Recipient addresses should be specified as per RFC5322.
            </p>After the view has been presented to the user, this method will no longer change the value.
@param      ccRecipients  A NSArray of NSString instances specifying the email addresses of recipients.

您应该设置删除并检测是否发生了错误：

- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
switch (result)
{
    case MFMailComposeResultCancelled:
        NSLog(@"Mail cancelled");
        break;
    case MFMailComposeResultSaved:
        NSLog(@"Mail saved");
        break;
    case MFMailComposeResultSent:
        NSLog(@"Mail sent");
        break;
    case MFMailComposeResultFailed:
        NSLog(@"Mail sent failure: %@", [error localizedDescription]);
        break;
    default:
        break;
}

// Close the Mail Interface
[self dismissViewControllerAnimated:YES completion:NULL];}
