MFMailComposersheet does not allocates in device iOS 5.1 version - iphone

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.

How to change message details (email body) in MFMailComposeViewController?

I seem to have fallen fowl of something that seems like it should be very simple!
How do I now populate an email's body with the strings a user has entered into NSUserDefaults?
Basically there is a button else ware that enters a sting such as 'YES' into NSUserDetaults. How do I make the email body those stored strings.
This is the code I currently have:
- (IBAction)buttonPressed:(id)sender {
MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:#"SYS"];
[controller setMessageBody:#"How do I make this the content of NSUSERDEFAULTS?" isHTML:NO];
controller.navigationBar.barStyle = UIBarStyleBlack;
[self presentViewController:controller animated:YES completion:nil];
Any help would be greatly appreciated!
Thanks!
Using your code the strings appear as : Yes, No, Maybe, No way,
How can I alter the format to make them appear
Yes,
No,
Maybe,
No way.
Thanks again for your time!
What you want is a line break character, which can be achieved with \n (newline).
NSArray *storedStrings = [[NSUserDefaults standardUserDefaults] objectForKey:#"yourStoredKey"];
NSMutableString *messageBody = [NSMutableString string];
for (NSString *aString in storedStrings) {
[messageBody appendFormat:#"%#,\n\n", aString];
}
[messageBody deleteCharactersInRange:NSMakeRange(messageBody.length-3, 3)];
[controller setMessageBody:messageBody isHTML:NO];
That line I added right after the for loop will remove the last three characters from the string, i.e. the two newline characters and the comma.
Try this method
- (IBAction)buttonPressed:(id)sender {
MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:#"SYS"];
[controller setMessageBody:[[nsstring stringwithformat#"%#",[[NSUserDefaults standardUserDefaults] objectForKey:#"yourStoredKey"]] isHTML:NO];
controller.navigationBar.barStyle = UIBarStyleBlack;
[self presentViewController:controller animated:YES completion:nil];

xcode mfmailcomposeviewcontroller lock setToRecipients

I have app that user contact me
The problem is that the users can put any email address, but I want to lock or do something to setToRecipients so that user can't make any change in this field.
Here is my code
MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init];
[composer setMailComposeDelegate:self];
if ([MFMailComposeViewController canSendMail]) {
[composer setToRecipients:[NSArray arrayWithObjects:#"123#abc.com", nil]];
[composer setSubject:#"subject here"];
[composer setMessageBody:#"message here" isHTML:NO];
[composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:composer animated:YES];
[composer release];
}
Any help or guide !!
thanx & regards
You can't as MFMailComposeViewController does not provide that functionality.
By the look of it, you can't. And the reason is that apple has safety protection to ensure you app doesn't auto send spam emails, in their point of view, it's the user should always have flexibility to choose where the email goes to.

MFMailComposer is not working in iPhone 3GS

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.

Problem with MFMailComposeViewController - User Can't Edit Mail Body - iPhone

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.

iPhone application lags after launching and dismissing MFMailComposeViewController

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;
