First, I should credit Craig for his example of drawing lines on a MKMapView (http://spitzkoff.com/craig/?p=108), that’s where you can find part 1 and part 2. This post is a teaser of what I am going to post later this month. It’s a improvement on his code and makes overlays on a MKMapView possible without the need to hide it when zooming/panning around.
The performance is pretty good. There is absolutely no lag on the iPhone 3GS, you will notice that panning/zooming around on the iPhone 3G is not that smooth as on the 3GS, but it’s acceptable.
I will publish it here on my blog when my app update is ready and Apple approved it. Will be in a month or so. If you actually found a way of doing this please let me now, I still looking for other ideas.
I do not have a lot of time to write a big blogpost, so I’m just going to post the code, and maybe later write the explanation.
