iphone - 适用于iOS 5的MFMailComposeViewController:教程或示例

有没有人有一个不错的教程，介绍如何以编程方式或使用segues为iOS 5实现Mail Composer？我在网上找到的大多数教程都来自旧的iOS版本。谢谢！

最佳答案

您可以执行以下操作：

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:@"[email protected]"]];

    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.");
