MFMailComposeController crashing non-deterministically
- by sss
Hello, I've been struggling with this issue for a few days. I am trying to use the MFMailComposeController to send emails. What's happening is that the program crashes (long stack-trace below) upon clicking the SEND button. However, this is non-deterministic - sometimes it works immediately, sometimes after a long delay, and most often, it crashes. Here's my code for sending:
-(void)mailWithAttachment:(NSString *) fileName
type:(NSString*) attachmentType
data:(NSData *) attachmentData {
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
if ([MFMailComposeViewController canSendMail]) {
[mc setSubject:@"my subject"];
[mc setMessageBody:@"my body" isHTML:YES];
[mc addAttachmentData:attachmentData
mimeType:attachmentType
fileName:fileName];
[self presentModalViewController:mc animated:YES];
}
[mc release];
}
didFinish result looks like you'd imagine:
-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
[self dismissModalViewControllerAnimated:YES];
//...some other actions here for other UI logic, but problem persists if removed
}
And the definition of the class:
@interface ShareViewController : UIViewController {
//...
}
Here's the stack trace:

I've tried the MFMailComposeController as a child of different views with the same result. Can anyone advise? I'd really appreciate it!
