I'm trying to create a map of the office I'm working at. I have a high resolution image, and would like to autorotate it in the direction the user is heading, allowing the user to navigate around the map. I thought this could be accomplished using CoreMotion/CoreLocation and a UIScrollView, but this seems like there's some work involved.
So I'm wondering if there are easier solutions for combining a custom map and direction/position on that map - can MapKit handle this for me? Are there other frameworks that can help me show a local 2D map with compass orientation on it?
You can convert your high-res image into map tiles easily with TileMill.
You should use some custom tiles with MKTileOverlay which only display at a very high zoom level (like z 18 or whatever). I suggest you take a look over at NSHipster and read what they have about it:

*Disclaimer: I haven't tried this myself, came across the NSHipster article while searching for solutions to my own problems.

I need to use a PNG as custom map of an indoor place. I don't need navigation but some places should be clickable like what we have in built in map. In android this is possible with MapView but I didn't find anything for iOS to do that. Can someone help me out how to start and do this?
A while back Apple added the ability to provide custom map overlay tiles. It isn't as simple as providing a PNG. You will need to create a database of map tiles at different scales, following a specific naming convention, and then provide a tiled map overlay.
I suggest looking at this blog post:
Custom and Offline Maps Using Overlay Tiles from VIGGIOSOFT
It goes into quite a bit of detail on what's required.
I have made an OpenLayers 3 web application I use while driving. It would be very handy to have the speed of the car in one corner of the map. Is it possible to achieve this so that the text (numbers) are locked to the viewport of the map rather than the map itself. I'm thinking of something similar to the controls of the map.
I suppose I could put it below the map but then I'm afraid I would run into problems with different sizes of screens.
Could somebody suggest a technique I should look into?
Is there any way to show only the pure map in ios? Without any text, label or annotation.
Sample iOS Map
For ex, in that picture there is a lot of texts, labels..
Somehow... From iOS7 you can provide your own tiles, but you lose map kit original tiles.
Mattt has written an interesting post on NSHipster, you should check it
Another option is to try the Mapbox tools to allow full map customization.
I would love to reproduce GoogleHeart-like 3D map flyover even when offline.
As of iOS 7 MapKit allows us to draw custom offline tiles. It also allows us to set a Camera in order to see the map in 3D or 2.5D as you may wish to call it.
I was wondering: can I draw a 3D shape like Apple does for its flyover feature, on my custom tiles?
I need to apply a "bump-map" to the map in order to get a GoogleHeart-like 3D view and I was wondering if Apple would allow me to do just that with iOS 7 and custom tiles rendering + camera settings.
Thanks
I have experimented pretty extensively with this, but there is no supported way to do this. Right now, Apple only offers raster tile-based overlay, albeit with automatic 2.5/3D transformation when overlaid on a map. Hopefully in the future they will support 3D API and/or custom, say, OpenGL-based augmentation to the map.
I'd like to provide custom navigation maps in my iOS 6 application. I've tried adding overlay views that shows these custom maps in MKMapView and it didn't work well because it needs a higher zoom level than what Apple's component can provide (the desired zoom level is about 10 screen points per meter in the map).
The question is, is subclassing MKMapView a good way to approach to this? The primary reason is I'd like to take advantage of MKMapView's coordinate conversion functions:
convertCoordinate:toPointToView:
convertPoint:toCoordinateFromView:
convertRegion:toRectToView:
convertRect:toRegionFromView:
Those functions makes it easy to convert screen points to world coordinates (latitude/longitude) and vice-versa.
Thanks in advance!
I don't think you are going to have much luck with subclassing MKMapView. There is a lot going on behind the scenes related to tile loading that you cannot access.
I would guess you would be better served using something along the lines of the MapBox iOS SDK or another similar map engine.
It allows you to specify your own tile sources and has plenty of examples to show you how it is done. It also had functions, like map kit, to handle converting values to and from lat/lon.
