Question

I was wondering if there is a way to allow the user to select an image from the camera roll, and then attach it to an email?

Here is the code I have now:

-(IBAction) openEmail {

MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
[mailComposer setMailComposeDelegate:self];
if ([MFMailComposeViewController canSendMail]) {
    [mailComposer setToRecipients:[NSArray arrayWithObjects:@"[e-mail]", nil]];
    [mailComposer setSubject:@"Learning Trail Submission"];
    [mailComposer setMessageBody:emailbody isHTML:NO];
    [mailComposer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Answer" ofType:@"plist"];
    NSData *myData = [NSData dataWithContentsOfFile:path];
    [mailComposer addAttachmentData:myData mimeType:@"application/xml" fileName:@"Answer.plist"];

    [self presentModalViewController:mailComposer animated:YES];
}
}

There sure is!

In your .h file add these delegates and declare a UIImage named selectedImage.

<UIImagePickerControllerDelegate, UINavigationControllerDelegate>

Then in your .m you can add the following.

Link -(IBAction)openImagePicker:(id)sender to the button that you want to start the process.

- (IBAction)openImagePicker:(id)sender
{

    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary])
    {
        UIImagePickerController *imagePicker =
        [[UIImagePickerController alloc] init];
        imagePicker.delegate = self;
        imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        imagePicker.allowsEditing = NO;
        [self presentViewController:imagePicker animated:YES completion:nil];
    }
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
    [self dismissViewControllerAnimated:YES completion:^{
        [self openEmail];
    }];

}

-(IBAction) openEmail {

    MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
    [mailComposer setMailComposeDelegate:self];
    if ([MFMailComposeViewController canSendMail]) {
        [mailComposer setToRecipients:[NSArray arrayWithObjects:@"[e-mail]", nil]];
        [mailComposer setSubject:@"Learning Trail Submission"];
        [mailComposer setMessageBody:emailbody isHTML:NO];
        [mailComposer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];

        NSString *path = [[NSBundle mainBundle] pathForResource:@"Answer" ofType:@"plist"];
        NSData *myData = [NSData dataWithContentsOfFile:path];
        [mailComposer addAttachmentData:myData mimeType:@"application/xml" fileName:@"Answer.plist"];
        NSData *imageData = UIImageJPEGRepresentation(selectedImage, 1.0);
        [mailComposer addAttachmentData:imageData  mimeType:@"image/jpg"   fileName:@"imageTitle"];
        [self presentModalViewController:mailComposer animated:YES];
    }
}

EDIT: Mind you this is a very basic example that doesn’t handle events such as the user selecting a video instead of an image…
