Mail Composer won't dismiss iOS

Question

I have ViewController with button, and action on button:

        - (IBAction)clickMe:(id)sender {
            MailHelper *helper = [[MailHelper alloc] init];
            [helper setAllData:self];
        }

Also, there is helper class for mail composing (MailHelper.h):

    #import <Foundation/Foundation.h>
    #import <UIKit/UIKit.h>
    #import <MessageUI/MessageUI.h>

    @interface MailHelper : UIViewController<MFMailComposeViewControllerDelegate>

    @property MFMailComposeViewController* mailView;
    - (void)setAllData:(UIViewController *)ctrl;

    @end

and implementation (MailHelper.m):

- (void)setAllData:(UIViewController *)ctrl {

    mailView = [[MFMailComposeViewController alloc] init];
    mailView.mailComposeDelegate = self;

    mailView.toRecipients = @[@"[email protected]"];
    [mailView setSubject:@"Subject"];

    [ctrl presentViewController:mailView animated:YES completion:nil];
}

-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {

    [self dismissViewControllerAnimated:YES completion:nil];
}

I can open mail composer, but while sending mail, saving draft or deleting draft app crashes. Any ideas?

Ok guys. Solution is to make instance of helper somewhere else, let's say:

@implementation ViewController
MailHelper *helper;

and:

- (IBAction)clickMe:(id)sender {
    helper = [[MailHelper alloc] init];
    [helper setAllData:self];
}
