iOS: Allow capturing photos using UIImagePickerController until cancel button clicked
===

I am implementing camera functionality where I need to allow users to take photos as many they like and store them. I am able to do this but one photo at a time! USer has to click again takePhoto button to open camera and capture photo. I am trying to not dismiss UIImagePickerController after photo has been saved but it's not working! Please see my following code. Could someone please tell me how could I allow users to keep taking picture until they click cancel button on UIImagePickerController. Thanks.


    - (IBAction)takePhoto:(id)sender 
    {

        if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])
        {
            UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
            imagePicker.delegate = self;
            imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
            imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
            [self presentModalViewController:imagePicker animated:YES];
        } 
    } 

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
    {
        NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    
        if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) 
        {
            UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
            NSData *imageData = UIImageJPEGRepresentation(image, 1);
           [imageData writeToFile:[delegate filePath:imageName] atomically:YES];
        }
    
        [picker dismissModalViewControllerAnimated:YES]; --> If I remove this then Camera stays open but Photo click button gets disabled! If I don't remove this it dismiss the camera.

    }

    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
    {
        [picker dismissModalViewControllerAnimated:YES];
    }
