• This is an annotation view that sports a callout bubble with multiple, independently selectable rows of data. The objective is to allow each cell/row to utilize an accessory disclosure button, without resorting to a more involved UITableViewController scenario.

(See the demo for a functional representation of this project.)

• Presuming you've already set up your project to use the MapKit Framework, you first need to add the appropriate classes in the "MultiRowCalloutAnnotationView" directory.
• Next, ensure your annotation class (if you have a preexisting one) answers to the "title" selector, and that it also returns an array of MultiRowCalloutCells upon request.
• The callout cell class takes a title, subtitle, and an image. You can also supply an NSDictionary for custom data that is passed along on accessory button touches.
• The MultiRowCalloutAnnotationView gathers the necessary information and conveniently uses blocks to handle the button touch events.

A portion of this class is based on James Rantanen's work at Asynchrony Solutions
