iPhone应用程序在启动和解除mfmailcomposeviewController后会滞后

我有一个应用程序,它使用表视图控制器来显示一些项目,单击其中一个项目后,您可以选择通过电子邮件发送此项目。一旦发生这种情况,我就使用苹果“邮件编辑器”提供的代码,并发送邮件。然而,在这之后,表视图中的滚动就不像以前那样平滑了。

我检查了“leaks”,代码中没有泄漏,但是当mfmailcomposeviewcontroller的模式视图控制器,以及当我解除控制器时,所有的对象分配仍然存在时,会有大量的对象分配。我怎样才能摆脱所有的对象分配呢?任何帮助都将不胜感激。谢谢您。

更新:

我已经意识到,只有当您单击mfmailcomposeviewController上的to:textfield并键入某些内容时,才会发生延迟,一旦键入了某些内容,就会出现内存泄漏,应用程序也会迟缓。同样的事情也发生在苹果的邮件作曲家身上。我用的是模拟器也许这就是为什么?.其他人有席米拉的经验吗?

我给控制器施压的方式是:

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

    NSString *mailSubject = appDelegate.mailTitle;
    NSString *mailBody = appDelegate.mailLink;

    NSString *formattedString = [NSString stringWithFormat:@"<a href='%@'>%@</a>", mailBody, mailBody];

    [picker setSubject:mailSubject];

    // Set up recipients
    //NSArray *toRecipients = [NSArray arrayWithObject:@"somemail@hotmail.com"]; 
    //NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil]; 
    //NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"]; 

    //[picker setToRecipients:toRecipients];
    //[picker setCcRecipients:ccRecipients];    
    //[picker setBccRecipients:bccRecipients];

    // Attach an image to the email (Warning this causes a memory leak aknowledged by Apple)
    //NSString *path = [[NSBundle mainBundle] pathForResource:@"news_icon" ofType:@"png"];
    //NSData *myData = [NSData dataWithContentsOfFile:path];
    //[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"];

    // Fill out the email body text
    [picker setMessageBody:formattedString isHTML:YES];

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

把它放在这里:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 
{   
    ....
    [self dismissModalViewControllerAnimated:YES];
}
