问题:

I want to develop a mall navigator however i am unsure where to start. I want to create something similar to this screenshot - http://navigationapps.com/wp-content/uploads/2010/10/point-inside-2.png . I believe its a custom loaded map with a pin tracker on it however how can i do this? (are there any tutorials/examples i could look at?). Furthermore, assuming that the mall has a clear signal, how accurate will the tracking be - within how many meters?). Would appreciate some help on this. Thanks.

Recently I had to develop an app using MKMapView using custom callouts (annotations). You won't get around subclassing MKAnnotationView if you want to do a lot of customizations to it.

What helped me most were those tutorials:
