MFMailComposeViewController crashing while dismissModalViewControllerAnimated in iOS5

Question

I am using MFMailComposeViewController in my conde to provide Mail functionality but after sending mail or when i want to cancel mail it will be crashing.

below is my code:

(IBAction)FnForPlutoSupportEmailButtonPressed:(id)sender {
{
    if ([MFMailComposeViewController canSendMail])
    {
        MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];

        mailer.mailComposeDelegate = self;

        [mailer setSubject:@"Need help from Pluto support team"];

        NSArray *toRecipients = [NSArray arrayWithObjects:@"[email protected]",nil];
        [mailer setToRecipients:toRecipients];


        NSString *emailBody = @"";

        [mailer setMessageBody:emailBody isHTML:NO];

        //mailer.modalPresentationStyle = UIModalPresentationPageSheet;

        [self presentModalViewController:mailer animated:YES];

    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Failure"
                                                        message:@"Your device doesn't support the composer sheet"
                                                       delegate:nil
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles: nil];
        [alert show];
    }
} }

    (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
// Notifies users about errors associated with the interface    
switch (result)
    {       case MFMailComposeResultCancelled:
                        break;
                    case MFMailComposeResultSaved:
                        break;
                    case MFMailComposeResultSent:
                        break;
                    case MFMailComposeResultFailed:
                        break;
                    default:
                        break;
    } 
    [self dismissModalViewControllerAnimated:YES];
     }

I have read all blog post but no solution is found, This blog post is having good explaination about this but as per this i am not presenting my view controller in viewdidload or viewdidappear.

I'm Getting EXE_BAD_ACCESS, Following is the crash log :

As per updated document of apple for ios 5 they mentioned :

presentModalViewController:animated:

Presents a modal view managed by the given view controller to the user. (Deprecated. Use presentViewController:animated:completion: instead.)

- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated
Parameters

Dismisses the view controller that was presented by the receiver. (Deprecated. Use dismissViewControllerAnimated:completion: instead.)

- (void)dismissModalViewControllerAnimated:(BOOL)animated

I had tried this also but it still crashes

Answer 1

If your are having sharekit framework implemented in your code goto SHK.m and change

        [[currentView parentViewController] dismissModalViewControllerAnimated:YES];

to

        [currentView  dismissModalViewControllerAnimated:YES];

This will solve your problem.

Thanks everyone for response.

and also comment these lines

SHKSwizzle([MFMailComposeViewController class], @selector(viewDidDisappear:), @selector(SHKviewDidDisappear:));
if (NSClassFromString(@"MFMessageComposeViewController") != nil) SHKSwizzle([MFMessageComposeViewController class], @selector(viewDidDisappear:), @selector(SHKviewDidDisappear:));
