I have this piece of code for MFMailComposer working fine in the simulator and iPhone 4, but it crashes on 3GS. What is the reason and what is the way to resolve it?
I checked it with breakpoints. mailPicker is not allocated with memory.
MFMailComposeViewController *mailPicker = [[MFMailComposeViewController alloc] init];
mailPicker.mailComposeDelegate = self;
// Set the subject of email
[mailPicker setSubject:#"Somebody got place in my sh*t list"];
NSString *emailBody = #"I just added somebody to my s**t list";
// This is not an HTML formatted email
[mailPicker setMessageBody:emailBody isHTML:NO];
// Create NSData object as PNG image data from camera image
NSData *data = UIImagePNGRepresentation([self captureScreen]);
// Attach image data to the email
// 'CameraImage.png' is the file name that will be attached to the email
[mailPicker addAttachmentData:data mimeType:#"image/png" fileName:#"CameraImage"];
// Show email view
[self presentModalViewController:mailPicker animated:YES];
// Release picker
[mailPicker release];
If at least one email account is enabled on the device, the following call should return YES:
[MFMailComposeViewController canSendMail]
Conversely, if all accounts are disabled/removed, it will return NO.

I want to send email without showing MFMailComposeViewController. I just want to send email to some sequence of emails (so user should see only my spinner, not MFMailComposeViewController with send button).
The only way to send emails I know is: (but it's not I want)
-(void)showMessageController:(id)sender
{
Class mailClass = (NSClassFromString(#"MFMailComposeViewController"));
if (mailClass != nil)
{
// We must always check whether the current device is configured for sending emails
if ([mailClass canSendMail])
{
[self displayComposerSheet];
}
else
{
[self launchMailAppOnDevice];
}
}
else
{
[self launchMailAppOnDevice];
}
}
// Displays an email composition interface inside the application. Populates all the Mail fields.
-(void)displayComposerSheet
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
[appDelegate setNavigationBarTextured:YES navigationBar:picker.navigationBar];
picker.mailComposeDelegate = self;
[picker setSubject:#"Please, look at my photo!"];
// Attach an image to the email (mydata - data of the image)
[picker addAttachmentData:myData mimeType:#"image/png" fileName:#"photo"];
// Fill out the email body text
NSString *emailBody = #"Hello!\nPlease, have a look at my photo!";
[picker setMessageBody:emailBody isHTML:NO];
[self presentModalViewController:picker animated:YES];
[picker release];
}
// Launches the Mail application on the device.
-(void)launchMailAppOnDevice
{
// NSString *recipients = #"mailto:first#example.com?cc=second#example.com,third#example.com&subject=Hello from California!";
NSString *recipients = #"mailto:subject=Please, look at my photo!";
NSString *body = #"&body=Hello!\nPlease, have a look at my photo!";
NSString *email = [NSString stringWithFormat:#"%#%#", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}
How can I send email without additional screen of MFMailComposeViewController?
Thank you in advance!
You can do it by Web services. Write a web service that takes message for Email body and receiver's email address, subject etc as parameters and sends mail from backend.
You can create PHP script to send email and can call the php service call with To, Message, Subject passed from device,
There is no API provided by Apple that would let you send emails without user interaction.
I have the following line of code,
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:APP_NAME];
[picker addAttachmentData:pdfData mimeType:#"pdf" fileName:pdfFileName];
NSString *emailBody = #"";
[picker setMessageBody:emailBody isHTML:YES];
[self presentModalViewController:picker animated:YES];
But iPad just stuck at the first line of the code.
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
When i put the break point on the another line it does not come to the second line of code it is just stuck and does not open MailCompserSheet and it is hung.
This problem appears only on iOS version 5.1 in iPad.
So anyway have idea what to do?
I guess you might not have configured mail in your iPad.
So before initializing the class MFMailComposeViewController, call MFMailComposeViewController's + (BOOL)canSendMail to check whether you can be able to send mail with the device or not.
In my iPhone app, I have a view where I am showing the names of files stored in the Documents directory.
These files are downloaded from a server, and now I want to implement an email function into my application.
My questions are:
Can I attach more than one file, and if so, what is yhe maximum number of files that can be attached?
When I attach a file, do I have to give the location where it is stored?
Assuming you're using the stock MFMailComposeViewController, you can add more than one attachment using addAttachmentData:mimeType:fileName:. You have to attach the raw data, so you'll need to fetch the file from disk and get an NSData representation. Here's an example of how to add to add a UIImage as an attachment:
MFMailComposeViewController *mvc = [[MFMailComposeViewController alloc] init];
mvc.mailComposeDelegate = self;
[mvc setSubject:#"My Subject"];
[mvc setMessageBody:#"My Message Body" isHTML:NO];
NSData *imageData = UIImageJPEGRepresentation(myImage, 1);
[mvc addAttachmentData:imageData mimeType:#"image/jpeg" fileName:#"image.jpg"];
[self presentModalViewController:mvc animated:YES];
[mvc release];
I usually use the below code to allow the user to submit feedback on my apps. However for some reason in my OpenGL app the below code has a problem. It opens the email form correctly, however the form is locked - i.e the user can't actually edit the body of the text. Can anybody spot why this is happening ?
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Feedback on Stop That Bomb Free !"];
NSArray *toRecipients = [NSArray arrayWithObject:#"anemail#gmail.com"];
[picker setToRecipients:toRecipients];
// Fill out the email body text
NSString *emailBody =
[NSString stringWithFormat:#"Hi Martin, I would like to make the following comment : "];
[picker setMessageBody:emailBody isHTML:YES];
picker.navigationBar.barStyle = UIBarStyleBlack;
[inputController presentModalViewController:picker animated:YES];
[picker release];
From reading your code I can find some things you should change:
Replace:
NSString *emailBody = [NSString stringWithFormat:#"Hi Martin, I would like to make the following comment : "];
With:
NSString *emailBody = #"Hi Martin, I would like to make the following comment : ";
As you are not using any formatting; you dont need to call the class method to create the simple string.
The other thing you can change is the fact that you message does not contain HTML.
So you dont need isHTML:YES.
I have tested this successfully on a sample app.
I imagine the problem is with the view controller presenting the view, rather than the messageUI view.
I have an application that uses a table view controller to display some items, after clicking on one of those items you may select to email this item. Once that happens I use the code provided by apple "MailComposer", and send the mail. However after this the scrolling in the table view is not as smooth as before.
I checked with "Leaks" and there are no leaks in my code, however there is a great deal of object allocation when the modal view controller for the MFMailComposeViewController, and when i dismiss my controller, all that object allocation is still there. How can i get rid of all that object allocation?. Any help will be greatly appreciated. Thank you.

UPDATE:
I have realized the lag only happens once you click on the To: textfield on the MFMailComposeViewController and type something, once something has been typed there will be a memory leak and the application will be sluggish. This exact same thing also happens in Apple's Mail Composer. I am using the simulator maybe this is why?. Does anyone else have a simmilar experience?
The way I am pressenting my controller is:
-(void)displayComposerSheet
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
NSString *mailSubject = appDelegate.mailTitle;
NSString *mailBody = appDelegate.mailLink;
NSString *formattedString = [NSString stringWithFormat:#"<a href='%#'>%#</a>", mailBody, mailBody];
[picker setSubject:mailSubject];
// Set up recipients
//NSArray *toRecipients = [NSArray arrayWithObject:#"somemail#hotmail.com"];
//NSArray *ccRecipients = [NSArray arrayWithObjects:#"second#example.com", #"third#example.com", nil];
//NSArray *bccRecipients = [NSArray arrayWithObject:#"fourth#example.com"];
//[picker setToRecipients:toRecipients];
//[picker setCcRecipients:ccRecipients];
//[picker setBccRecipients:bccRecipients];
// Attach an image to the email (Warning this causes a memory leak aknowledged by Apple)
//NSString *path = [[NSBundle mainBundle] pathForResource:#"news_icon" ofType:#"png"];
//NSData *myData = [NSData dataWithContentsOfFile:path];
//[picker addAttachmentData:myData mimeType:#"image/png" fileName:#"rainy"];
// Fill out the email body text
[picker setMessageBody:formattedString isHTML:YES];
[self presentModalViewController:picker animated:YES];
[picker release];
}
and dimissing it here:
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
....
[self dismissModalViewControllerAnimated:YES];
}
It's a known memory leak in MFMailComposeViewController class (as of iOS 4.2 SDK). The leaks can be even seen in the MailComposer sample project by Apple. Try to run the app with Allocations instrument and notice the Overall Bytes growing up every time you click cancel and show the composer again.

Make sure you use
controller.mailComposeDelegate = self;
and not
controller.delegate = self;
