UIScrollView and presentModalViewController

Question

I add UITableViewController in UIScrollView. When I call

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;
    [picker setSubject:@"Email"];
    [picker setMessageBody:currentcelltext isHTML:NO];
    [self presentModalViewController:picker animated:YES];
    [picker release];

MFMailComposeViewController is coming in UIScrollView. So, I can't press cancel and send button.

How to fix it ?
