How do you set the avatar of API-triggered messages?

When sending messages through a web-request - you can supply the icon_emoji property with a supported emoji name, such as:

{
    ..
    "icon_emoji":":ghost"
}

Or, with an icon_url property:

{
    ..
    "icon_url":"<your valid url>"
}

    user.setObject(imageFile, forKey: "photo")

    user.signUpInBackgroundWithBlock {
        (succeeded: Bool!, error: NSError!) -> Void in
            if error == nil {
               // Hooray! Let them use the app now.
               self.messageLabel.text = "User Signed Up";
            } else {
                // Show the errorString somewhere and let the user try again.
            }
    }
