如何使用非Google地图在iPhone应用程序中绘制自定义“标注气泡”（地名透明灰色叠加层）？

Question

I'm building an iPhone application with a map inside (using route-me, not MapKit).

I have some markers on the map, and I want to have an overlay - similarly to the google maps one - that appears once you click a marker:
A black - a bit transparent - overlay, with a button inside, and a little triangle pointing to the marker the overlay is referencing.

Thank you.

Answer 1

Read the quartz2d docu from Apple. They explain in detail how to create custom views.

Answer 2

It looks like these things are called 'callout bubbles'. Apple has a MapCallouts sample that shows you how to customize them.
