I GUESS YOU ARE NOT IMPORTING FRAMEWORK
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
#interface MailClassViewController : UIViewController<MFMailComposeViewControllerDelegate>
And then the code to present the email screen:
- (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];
}
