MFMailComposeViewController不允许用户输入电子邮件

Question

我在下面配置了一个简单的MFMailComposeViewController。如果我填充setToRecipients，一切正常，电子邮件将被发送。如果我没有填充setToRecipients，则会弹出邮件编辑器窗口，但所有字段都不可编辑。

我认为MFMailComposeViewController允许用户在发送之前编辑电子邮件？这是否可以使用标准控件？

- (IBAction) sendEmail
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;

    [picker setSubject:[NSString stringWithFormat:@"Receipt Email - %@",[self.labelDate text]]];

    NSString *emailBody = @"This is the message body";

    [picker setMessageBody:emailBody isHTML:NO];

    [self presentModalViewController:picker animated:YES];
    [picker release];   
}

别介意......我没有辞去父视图的第一响应者＆gt;。＆lt;通过添加[self.parentViewController resignFirstResponder]解决; [self becomeFirstResponder];
