Based on work at GitHub.
- 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
