Как отправить письмо по iPad - NSobject класс

Question

У меня есть проект очень просто как проекты Unity, и я хочу добавить новую функцию - отправка скриншота приложения электронной почты,

Я пытаюсь сделать это разными способами, но я не совсем в IOS и мне нужна твоя помощь:(

Эта версия работает без ошибок, но после нажатия на кнопку я не увидел форму электронной почты

код очень короткий и простой - я надеюсь, что кто-то помог мне (((

SampleViewsAppDelegate.h

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>
#import <MapKit/MKMapView.h>
#import <MessageUI/MessageUI.h>

#import "tiDFusionMobile.h"

@interface SampleViewsAppDelegate : NSObject     <UIApplicationDelegate,MFMailComposeViewControllerDelegate> {

    ///Application Window
    UIWindow *mWindow;

    UIViewController *rootViewController;

    ///Application views
    UIView    *mRender;

    tiComponent* mPlayer;
}

///IBOutlet properties
@property (nonatomic, retain) IBOutlet UIWindow *mWindow;
@property (nonatomic, retain) IBOutlet UIViewController *rootViewController;
@property (nonatomic, retain) IBOutlet UIView *mRender;

Я думаю, вы не импортируете рамки

#import <MessageUI/MessageUI.h> 
#import <MessageUI/MFMailComposeViewController.h> 
@interface MailClassViewController : UIViewController<MFMailComposeViewControllerDelegate>

А затем код для представления экрана электронной почты:

- (IBAction)openMailBtn:(id)sender {

if([MFMailComposeViewController canSendMail]) {
    MFMailComposeViewController *mailCont = [[MFMailComposeViewController alloc] init];
    mailCont.mailComposeDelegate = self;
    [mailCont setSubject:@"Your email"];
    [mailCont setMessageBody:[@"Your body for this message is " stringByAppendingString:@" this is awesome"] isHTML:NO];
    NSString *file = [documentsDirectory stringByAppendingPathComponent:@"MaintenanceRequest.pdf"];

   //IF YOU DONT WANT TO ATTACH FILE THEN COMMENT IT
    NSData *data=[NSData dataWithContentsOfFile:file];
    [mailViewController addAttachmentData:data mimeType:@"application/pdf" fileName:@"MaintenanceRequest.pdf"];

    [self presentViewController:mailCont animated:YES completion:nil];
 }

}

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
//handle any error
[controller dismissViewControllerAnimated:YES completion:nil];
}
