I'm trying to write a function with which the user can take and upload upload a pic to my server. I want to disallow users from selecting a picture from the Photo Roll though. Is there anyway I can do this using the ImagePicker pod? 

```
func cancelButtonDidPress(imagePicker: ImagePickerController) {
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
}

func wrapperDidPress(imagePicker: ImagePickerController, images: [UIImage]) {
}

func doneButtonDidPress(imagePicker: ImagePickerController, images: [UIImage]) {
    imagePicker.dismissViewControllerAnimated(true, completion: nil)
}

@IBAction func pictureButtonTapped(sender: AnyObject) {
    //take picture
    let imagePickerController = ImagePickerController()
    imagePickerController.imageLimit = 1
    imagePickerController.delegate = self
    presentViewController(imagePickerController, animated: true, completion: nil)
}

```
