Mapbox Callout Accessory

I was wondering if Mapbox had any other callout buttons rather than just the seven provided? 

let button = UIButton(type: .detailDisclosure)

Or if there was a quick fix to converting these UIButtons into UIImages in order to create my own buttons.

Yes, you can use the methods func mapView(_ mapView: MGLMapView, leftCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? and func mapView(_ mapView: MGLMapView, rightCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? to create your own. Set the button type to .custom

For example:

func mapView(_ mapView: MGLMapView, leftCalloutAccessoryViewFor annotation: MGLAnnotation) -> UIView? {
    // We're not concerned with the user annotation.
    guard annotation is CameraAnnotation || annotation is NoteAnnotation else {
        return nil
    }
    // Callout height is fixed; width expands to fit its content.
    let deleteButton = UIButton(type: .custom)
    deleteButton.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
    deleteButton.setImage(UIImage(named: "delete"), for: .normal)
    deleteButton.tag = 100
    return deleteButton
}
