how to create customer map on iPhone without using Google Map

I'm trying to integrated in our iOS app. Due to the bad relationship between Google & our government, Google Map is not a good idea.

We have bought a local map service company's javascript & Web Services based SDK, now we want to use it on iOS. But it seems that MapKit does not support customer tiles.

So here are my current ideas:

• Use UIWebView. But I tried that map in Safari, I can't drag to move the map nor use two fingers to zoom. I think I need to call some javascripts while touch events happens.

• Build a costumer UIScrollView, download map images and display them using iOS sdk. But that map service does not have API to download images, I tried to read their 200KB+ undocumented javascript to find out the relationship between location &开发者_高级运维 image files, but I got no results for now.

Both the two ways could face certain legal risks. I'm not sure what the purchase contract is like.

I need suggestions about the two ways or some new ideas. Thanks guys.

There are a couple of non-Google map implementations available on github that you might be able to use (linked via CocoaControls):

• NAMapKit
• MRMapView
