Standart AnnotationView with Multiline in MKMapView

I want to show my descriptio开发者_运维百科n of Annotation with several lines of text (such as phone, description, address), I found the solution here. I must create my own child MKAnnotationView class and override method initWithAnnotation, where I'm able to draw background rectangle and all my labels with all settings I need. But I want to have standard background rectangle, it's rather pretty. Thanks for your help.
