I am having difficulties adding the ability for a user to send a support email to myself (the maker of said app). I have gotten it work almost perfectly however the view doesn't close when you click cancel, or when you click send. Thanks for the help!
Here is the code:
MFMailComposeViewController *mail = [[[MFMailComposeViewController alloc] init] autorelease];
mail.mailComposeDelegate = self;
[mail setToRecipients:[NSArray arrayWithObject:#"support#lindahlstudios.com"]];
[mail setSubject:#"Fraction Calculator Lite Support"];
[self presentModalViewController:mail animated:YES];
You're setting self to be the MFMailComposeViewController's delegate. In mailComposeController:didFinishWithResult:error: be sure to call
[self dismissModalViewControllerAnimated:YES];
like so:
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[self dismissModalViewControllerAnimated:YES];
}
You need to implement the delegate method from MFMailComposeViewControllerDelegate.
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self dismissModalViewControllerAnimated:YES];
}

I use MFMailComposeViewController to send emails in my app.
When I run my app with Instruments,
I see a leak after I tapped to send the email.
Leaked Object # Address Size Responsible Library Responsible Frame
MutableMessageHeaders,1 0x6be950 32 Bytes MessageUI +[MFComposeTypeFactory headersFromDelegate:]
_MFOutgoingMessageBody,1 0x1190ed0 32 Bytes Message -[MessageWriter createMessageWithPlainTextDocumentsAndAttachments:headers:]
Do you know how to fix it,
is this a leak in MessageUI framework?
- (void)showMailComposer
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Subject"];
NSString *emailBody = #"Email body";
[picker setMessageBody:emailBody isHTML:NO];
[self presentModalViewController:picker animated:YES];
[picker release];
}
#pragma mark -
#pragma mark Dismiss Mail/SMS view controller
// Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the
// message field with the result of the operation.
- (void)mailComposeController:(MFMailComposeViewController*)controller
didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[self dismissModalViewControllerAnimated:YES];
}
Yeah, looks like it. But at a total of 64 bytes per sent email, it’s not one you should be worried about.
I am using xcode 4.2 and i am developing an iphone APP , part of this app is sending SMSs
here is the code that I typed:
-(IBAction)SMSbutton{
MFMessageComposeViewController *sms = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText]) {
sms.body= [NSString stringWithFormat: #"text"];
sms.messageComposeDelegate = self;
[self presentModalViewController:sms animated:YES];
}
I can open the SMS application and send SMS but the problem is whether I click on the "cancel" or the "send" button the message application does not go away . how to do that ?
thanks
Set your calling class to be a delegate of the message composer, then catch the cancel and send events to dismiss the modal view controller as needed.
Set your header file to adhere to the MFMessageComposeViewControllerDelegate, and when you initialize the composer, set the message delegate to self:
MFMessageComposeViewController *george = [MFMessageComposeViewController alloc] init];
george.messageComposeDelegate = self;
Then implement the delegate method...easiest way is:
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissModalViewControllerAnimated:YES];
}
...but you can catch and deal with errors and events as necessary.
Implement messageComposeViewController:didFinishWithResult: in your delegate"
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
if(result == MessageComposeResultCancelled) {
//Message cancelled
} else if(result == MessageComposeResultSent) {
//Message sent
}
[self dismissModalViewControllerAnimated:YES];
}
Have you tried dismissViewControllerAnimated:completion: or dismissModalViewControllerAnimated:?
[self dismissModalViewControllerAnimated: YES];
when I press the sendMail button, it will go to the mail button, but when I hit send or cancel it will not take me back to my application. Any suggestions?
-(IBAction)sendMail {
MFMailComposeViewController *mailComposer = [[[MFMailComposeViewController alloc] init] autorelease] ;
if ([MFMailComposeViewController canSendMail]) {
[mailComposer setToRecipients:nil];
[mailComposer setSubject:nil];
[mailComposer setMessageBody:#"Default text" isHTML:NO];
[self presentModalViewController:mailComposer animated:YES];
}
}
You need to set a delegate (generally the same view controller that presented the MFMailComposeViewController). Then when the user taps the Save or Cancel button the MFMailComposeViewController will call -mailComposeController:didFinishWithResult:error on the delegate. So set yourself as the delegate and define the following method:
#pragma mark -
#pragma mark MessageUI Delegate Methods
- (void)mailComposeController:(MFMailComposeViewController*)controller
didFinishWithResult:(MFMailComposeResult)result
error:(NSError*)error {
[controller dismissModalViewControllerAnimated:YES];
}
Add the following line below your mail composer initialization
mailComposer.mailComposeDelegate = self;//very important if you want feedbacks on what the user did with your email sheet.
Then implement the delegate method as Kenny suggested. You can use this method to take custom actions.
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
// Notifies users about errors associated with the interface
switch (result)
{
case MFMailComposeResultCancelled:
{
//Do something, If you need to
}
break;
default:
break;
}
[self dismissModalViewControllerAnimated:YES];
}
Remember to conform to the delegate by adding
#interface YourViewController : UIViewController <MFMailComposeViewControllerDelegate> { }
If you are still having trouble, You may visit the following tutorial where everything nicely explained:
http://blog.mugunthkumar.com/coding/iphone-tutorial-in-app-email/
This wonderful line:
mailComposer.mailComposeDelegate = self;
is what made it happen for days without knowing that was what went wrong.
And do not forget them:
# import <UIKit/UIKit.h>
# import <MessageUI/MessageUI.h>
# import <MessageUI/MFMailComposeViewController.h>
In addition to importing the MessageUI.framework in the project.

I'm having difficulties closing an email message that I have raised.
The email opens nicely, but once it is opened it will not close as the mailComposeController:mailer didFinishWithResult:result error:error handler never gets invoked.
As far as I can tell I have all the bits in place to be able to do this.
Anyone any ideas of what I can look at?
Here is how I raise the email:
-(IBAction)emailButtonPressed
{
NSString *text = #"My Email Text";
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.delegate = self;
[mailer setSubject:#"Note"];
[mailer setMessageBody:text isHTML:NO];
[self presentModalViewController:mailer animated:YES];
[mailer release];
}
and later in the class I have this code to handle the close (but it never gets called):
-(void)mailComposeController:(MFMailComposeViewController *)mailer didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
[self becomeFirstResponder];
[mailer dismissModalViewControllerAnimated:YES];
}
My header file is defined as:
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
#interface myViewController : UIViewController <UIActionSheetDelegate, UIAlertViewDelegate, MFMailComposeViewControllerDelegate, UINavigationControllerDelegate>
Thanks

You are setting the delegate wrong, the delegate property in MFMailComposeViewController is called mailComposeDelegate, so it should be:
mailer.mailComposeDelegate = self;
Another possible error I can see is calling dismissModalViewControllerAnimated: on mailer - you should send this message to the view controller who presented the mail interface - self in this case:
[self dismissModalViewControllerAnimated:YES];
I wrote "possible error" because it might actually work if iOS routes the message through responder chain, anyway - the documentation says it should be send to presenter.
I add UITableViewController in UIScrollView. When I call
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Email"];
[picker setMessageBody:currentcelltext isHTML:NO];
[self presentModalViewController:picker animated:YES];
[picker release];
MFMailComposeViewController is coming in UIScrollView. So, I can't press cancel and send button.
How to fix it ?
I hope that you set MessageUI.framework in your xcode project..
After you have to set delegate in .h file..
than ,
you have to create one more method..
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
[self becomeFirstResponder];
[self dismissModalViewControllerAnimated:YES];
}
You might have fixed the issues.
This answer is for those who might come to this post with the expectation of answer.
To fix this you have to use delegation pattern. I assume all the pages in your scrollview are viewcontroller instances and scrollview is subview to viewcontroller.
This answer https://stackoverflow.com/a/626946/451867 can help you to implement delegate pattern in your project,
