Answer 1

Nie musisz wpisywać rozszerzenia w nazwie pliku. jak "iphone.jpg" nie działa. po prostu napisz "iphone" w nazwie pliku, ponieważ już zdefiniowałeś mimeType. Musisz także zdefiniować ścieżkę dla zasobu.

Poniżej znajduje się przykładowy kod dołączający plik "rainy.png" do wiadomości e-mail.

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
picker.mailComposeDelegate = self; 

[picker setSubject:@"Hello"]; 


// Set up recipients 
NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.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 
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"]; 
NSData *myData = [NSData dataWithContentsOfFile:path]; 
[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"]; 

// Fill out the email body text 
NSString *emailBody = @"It is raining"; 
[picker setMessageBody:emailBody isHTML:NO]; 

[self presentModalViewController:picker animated:YES]; 
[picker release];

Błąd ten wydaje się być związane z systemem pocztowym int on symulatorze, a nie w kodzie. Próbka nawet magazynie Apple MailComposer zgłasza identyczny błąd w symulatorze:

Dodaj następujący sposób oddalić MFMailComposeViewController:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult: (MFailComposeResult)result error:(NSError*)error 

{ 
// NEVER REACHES THIS PLACE 
[self dismissModalViewControllerAnimated:YES]; 

NSLog (@"mail finished"); 
} 

Answer 4

użycie tego dla dołączyć obraz w elektroniczną, testowane w iOS 4,5, 6

MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init]; 
    UIImage *myImage = [UIImage imageNamed:@"image.png"]; 
    NSData *imageData = UIImagePNGRepresentation(myImage); 
    [mailer addAttachmentData:imageData mimeType:@"image/png" fileName:@"image"];
