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 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 am developing an augmented reality application where it recognizes objects and change the colors real time (example color of walls of a house). Can I use Vuforia SDK for this or are there any other better sdks to be used ?
Basically yes - Vuforia is able to detect pre-known images and let you know when something was detected, and what you do then is up to you. However, it depends on the objects you plan to recognize - Vuforia does not allow just any image to be detected, the image must have enough features.

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.
In an iOS application, I want to draw a United States map with states and counties outlined. I also want to draw individual states with counties outlined. I have researched using Shapefiles to do the drawing, but I can't find a good API that translates shapefiles. I have looked into ArcGIS, but it seems most of the drawing they do is web/server based, also without the ability to draw individual states, or outline counties.
Does anyone know of a good iOS API I can use to draw the following maps?
United States with states and counties outlined
Individual state with counties outlined
Take a look at MapBox, it will let you draw these types of maps, then you can pull them in as tiles and overlay them with MapKit.
They also have an iOS SDK, http://mapbox.com/mapbox-ios-sdk/ if you don't want to use MapKit.
I think ArcGIS for iOS is your answer here. The iOS API will allow you to add a MapView to your application.
You can add one or more geoservices to that MapView, as well as local graphic layers.
MapServices are rendered server-side. FeatureServices are rendered client-side. You can also take features (each county or state would be a feature) from the FeatureService and put them into the graphic layer to implement different effects such as selection, outlining...
If you want to have all data stored in the client (the device), then you can embed the json representation of the features and add them to the graphics layer in the MapView, without needing to connect to any geoservice (although geo applications work better when connecting to a server)

This sample looks similar to what you are looking for: http://www.arcgis.com/home/item.html?id=417a0bf9dfda482c8110ebdbde3edd66

All good answers above. The solution that ended up working for me was to simply use an SVG image, drag it into PaintCode and PaintCode gives me all the code to draw the image. A very simple and elegant solution.
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.
