Question

有没有人有关于如何以编程方式或使用segues为ios 5实现邮件编辑器的体面教程？我在网上找到的大多数教程都来自旧的iOS版本。谢谢！

Answer 1

你可以这样做：

if([MFMailComposeViewController canSendMail])
{
    MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];
    [mailController setMailComposeDelegate:self];
    [mailController setSubject:@"Mail Subject!"];
    [mailController setMessageBody:@"Here is your message body" isHTML:NO];
    [mailController setToRecipients:[NSArray arrayWithObject:@"yourrecipent@domain.com"]];

    NSData *imageData = UIImageJPEGRepresentation(imageToUpload, 1.0f);
    if(imageData.length)
    {
        [mailController addAttachmentData:imageData mimeType:@"image/jpeg" fileName:@"Your_Photo.jpg"];
        [self presentModalViewController:mailController animated:YES];
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Invalid Image" message:@"The image couldn't be converted." delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Okay", nil];
        [alert show];
    }
}
else NSLog(@"Hah. No mail for you.");

首先你需要添加＆＃34; MFMailComposeViewControllerDelegate＆＃34;接口部分。

此外，您必须添加程序以在用户点击后发出响应＆＃34;发送按钮＆＃34;

- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
    switch (result) {
        case MFMailComposeResultSent:
            NSLog(@"You sent the email.");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"You saved a draft of this email");
            break;
        case MFMailComposeResultCancelled:
            NSLog(@"You cancelled sending this email.");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Mail failed:  An error occurred when trying to compose this email");
            break;
        default:
            NSLog(@"An error occurred when trying to compose this email");
            break;
    }

    [self dismissViewControllerAnimated:YES completion:NULL];

}
