iPhone - MessageUI 框架中的泄漏？

Question

我使用 MFMailComposeViewController 在我的应用程序中发送电子邮件。
当我使用 Instruments 运行我的应用程序时，
在我点击发送电子邮件后，我看到了泄漏。

Leaked Object   #   Address Size    Responsible Library Responsible Frame

MutableMessageHeaders,1 0x6be950    32 Bytes    MessageUI   +[MFComposeTypeFactory headersFromDelegate:]

_MFOutgoingMessageBody,1    0x1190ed0   32 Bytes    Message -[MessageWriter createMessageWithPlainTextDocumentsAndAttachments:headers:]

你知道怎么解决吗，
这是 MessageUI 框架中的泄漏吗？

- (void)showMailComposer
{
        MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
        picker.mailComposeDelegate = self;
        [picker setSubject:@"Subject"];
        NSString *emailBody = @"Email body";
        [picker setMessageBody:emailBody isHTML:NO];
        [self presentModalViewController:picker animated:YES];
        [picker release];
}

#pragma mark -
#pragma mark Dismiss Mail/SMS view controller

    // Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the 
    // message field with the result of the operation.
    - (void)mailComposeController:(MFMailComposeViewController*)controller 
              didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 
{
            [self dismissModalViewControllerAnimated:YES];
    }

是的，看起来像。但是每封发送的电子邮件总共有 64 个字节，这不是您应该担心的。
