How can I customize the title/subtitle font in cal

问题:

I have a view to a calloutDetail: annotationView.detailCalloutAccessoryView = mapInformationView.view

It is working just fine, but I don't want to display a title/subtitle, just my custom view. But when I left title/subtitle empty the callout isn't displayed.

So, How can I hide them or just change their font size and name?
