objective-c - 未收到从 iOS 应用程序/MFMailComposeViewController 发送的附件

Question

我正在使用 MFMailComposeViewController 从应用内发送附件 (pdf)。但是，当我在设备上测试时，我没有收到附件。知道可能是什么问题吗？

- (void) emailDocument 
{
    MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];

    NSData *data = [[NSData alloc] initWithContentsOfURL:pdfURL];


    mailController.mailComposeDelegate = self;

    [mailController setSubject:[self title]];
    [mailController setMessageBody:@"Please find the attached documents." isHTML:YES];
    [mailController addAttachmentData:data mimeType:@"application/pdf" fileName:@"document"];
    [self presentModalViewController:mailController animated:YES];
}

Answer 1

试着理解这段代码，它对你有帮助。

- (void)viewDidLoad 
{
if ([MFMailComposeViewController canSendMail])

    myButton.enabled = YES;
}


- (IBAction)buttonPressed 
{
MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];

    mailController.mailComposeDelegate = self;

    [mailController setSubject:@"Hello iPhone"];

    [mailController setMessageBody:@"This is the MailSend Application...." isHTML:NO];

    [self presentModalViewController:mailController animated:YES];

    [mailController release];
}  

- (void)mailComposeController:(MFMailComposeViewController*)mailController didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 
{
[self becomeFirstResponder];

    [self dismissModalViewControllerAnimated:YES];
}

谢谢
