How can I send emails from my custom UIActivity class? - ios

Question

I made a costume UIActivity class. I like to send emails with attachments with the class, but I can't send emails, or present any ViewControllers from the class. I am trying to present the Mail ViewController with this:
- (void)prepareWithActivityItems:(NSArray *)activityItems
{
NSString *subject = [NSString stringWithFormat:#"%#", [self.filePath lastPathComponent]];
NSString *messageBody = [NSString stringWithFormat:#"%# was extracted with #FilyForiOS, visit", [self.filePath lastPathComponent]];
NSData *attachment = [NSData dataWithContentsOfFile:self.filePath];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:subject];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:nil];
[mc addAttachmentData:attachment mimeType:[[self.filePath lastPathComponent] pathExtension] fileName:[self.filePath lastPathComponent]];
[self presentViewController:mc animated:YES completion:nil]; // Here is the error: No visible #interface for 'MailTo' declares the selector 'presentViewController:animated:completion:'
}
Can anyone tell me how I can present a ViewController from this class?
I used this code: How can I create a custom UIActivity in iOS?

Sorry that I'm just now answering this (I know this was asked along time ago) But here is my answer:
#import <MessageUI/MessageUI.h>
#interface EmailActivity : UIActivity <MFMailComposeViewControllerDelegate>
#end
#implementation EmailActivity
- (NSString *)activityTitle
{
// Your title
return #"Email";
}
- (UIImage *)activityImage
{
// Your image
return [UIImage imageNamed:#"Email"];
}
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
return YES;
}
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[self activityDidFinish:YES];
}
- (UIViewController *)activityViewController
{
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc]init];
if ([MFMailComposeViewController canSendMail])
{
NSString *subject = [NSString stringWithFormat:#"%#", [self.filePath lastPathComponent]];
NSString *messageBody = [NSString stringWithFormat:#"%# was extracted with #FilyForiOS, visit", [self.filePath lastPathComponent]];
NSData *attachment = [NSData dataWithContentsOfFile:self.filePath];
[mc setSubject:subject];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:nil];
[mc addAttachmentData:attachment mimeType:[[self.filePath lastPathComponent] pathExtension] fileName:[self.filePath lastPathComponent]];
mc.mailComposeDelegate = self;
return mc;
}
else
{
return nil;
}
}
#end
