Tagging the the map with comment and photo in iPhone

I have an application in iPhone in which I am now playing with MKMapView. However, I am getting stuck at one place, and it's hard for me to 开发者_Go百科find a solution for this.

I am stuck at tagging the Map with Photos and making comment on that location and on the photo. How can this possible to do? I think it's like drop annotation the map; it must display the map with photos and comment if it's possible.

I think you need check MKAnnotationView. It's a custom AnnotationView who Inherits from UIView. MKAnnotationView Class Ref
