I’m building an iOS app using MapKit that allows users to create and navigate trails. I need offline map functionality, I was wondering if MapKit supports that. If not I was wondering if MapBox is a viable alternative to MapKit though I would prefer using MapKit. Thanks!
If you're bringing your own map tiles, like one optimized for hiking, then it sure can! We have a dedicated section in one of our sample code projects just for that feature.
If you're looking to use Apple's own offline maps provided by the Maps app and then load that data in your app, that is not possible with the APIs available today, and so that's a great enhancement request that I suggest you file. If that's what you need, please post the FB number of your enhancement request here.
