I'm a software developer, and I'm making an application for the email message and I have the following code:
// Header file
// importing the MessageUI framework
#import <MessageUI/MessageUI.h>
// adding the delegate functionality to the class (<MFMailComposeViewControllerDelegate>)
@interface TutorialProjectViewController : UIViewController <MFMailComposeViewControllerDelegate> {
}
- (IBAction)pressTheMailButtonDudeFunction:(id)sender
// Implementation file
- (IBAction)pressTheMailButtonDudeFunction:(id)sender {
// allocatind new message composer window
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
// setting a delegate method to "self"
mc.mailComposeDelegate = self;
// pre-populating the message subject
[mc setSubject:@"Send me a message"];
// adding content of the message as a plain text
[mc setMessageBody:@"Send me a message is you like this tutorial :)" isHTML:NO];
// adding content of the message as an HTML
[mc setMessageBody:@"<p>Send me a message is you like this tutorial :)<p>" isHTML:YES];
// adding recipients
[mc setToRecipients:[NSArray arrayWithObjects:@"Fuerte <[email protected]>", @"[email protected]", nil]];
// adding recipients for a send copy to (arrayWithObject or arrayWithObjects)
[mc setCcRecipients:[NSArray arrayWithObject:@"[email protected]"]];
// adding hidden recipients
[mc setBccRecipients:[NSArray arrayWithObject:@"[email protected]"]];
// adding image attachment
// getting path for the image we have in the tutorial project
NSString *path = [[NSBundle mainBundle] pathForResource:@"Extra_Xcode_100x100" ofType:@"png"];
// loading content of the image into NSData
NSData *imageData = [NSData dataWithContentsOfFile:path];
// adding the attachment to he message
[mc addAttachmentData:imageData mimeType:@"image/png" fileName:@"Collection"];
// setting different than the default transition for the modal view controller
[mc setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
/*
Modal view controllers transitions:
UIModalTransitionStyleCoverVertical => pops up from the bottom, default transition
UIModalTransitionStyleCrossDissolve => fade on the screen
UIModalTransitionStyleFlipHorizontal => page flip
*/
// displaying our modal view controller on the screen (of course animated has to be set on YES if you want to see any transition)
[self presentModalViewController:mc animated:YES];
// releasing the controller
[mc release];
}
// delegate function callback
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
// switchng the result
switch (result) {
case MFMailComposeResultCancelled:
NSLog(@"Mail send canceled.");
/*
Execute your code for canceled event here ...
*/
break;
case MFMailComposeResultSaved:
NSLog(@"Mail saved.");
/*
Execute your code for email saved event here ...
*/
break;
case MFMailComposeResultSent:
NSLog(@"Mail sent.");
/*
Execute your code for email sent event here ...
*/
break;
case MFMailComposeResultFailed:
NSLog(@"Mail send error: %@.", [error localizedDescription]);
/*
Execute your code for email send failed event here ...
*/
break;
default:
break;
}
// hide the modal view controller
[self dismissModalViewControllerAnimated:YES];
}
And I'm not getting the proper answer... Is it a right code?
So, here's a "minimal" MFMailComposeViewController:
- (IBAction)showMinimalModalMailView:(id)sender {
// get a new new MailComposeViewController object
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
// his class should be the delegate of the mc
mc.mailComposeDelegate = self;
// set a mail subject ... but you do not need to do this :)
[mc setSubject:@"This is an optional mail subject!"];
// set some basic plain text as the message body ... but you do not need to do this :)
[mc setMessageBody:@"This is an optional message body plain text!" isHTML:NO];
// set some recipients ... but you do not need to do this :)
[mc setToRecipients:[NSArray arrayWithObjects:@"[email protected]", @"[email protected]", nil]];
// displaying our modal view controller on the screen with standard transition
[self presentModalViewController:mc animated:YES];
// be a good memory manager and release mc, as you are responsible for it because your alloc/init
[mc release];
}
