I want implement forward geocoding in my app. But I am not able to do that, though i have fair knowledge of mapkit and core Location. I am able to implement reverse geocoding.
So any one can provide a tutorial which tells step by step process to implement forward geocoding. Source code will be nice.
Please go through this sample by Merrimack. The link also provides a source code with a sample showing how the geo coding works. Hope this helps.

I have created my own maps of US states that I want to use in my app. I would like to use GPS to reference the user's position as well as various locations I have entered into my database.
Does anyone know of any guides for doing this? My main issue is in converting the known points on my map to something my app can understand and reference.
If you are new to this subject, the wikipedia article on map projection is really good and could provide a starting point: http://en.wikipedia.org/wiki/Map_projection
I would like to user route-me in a mapping application because I need to support disconnected use 90% of the time.
I have looked at their tutorials, but I am looking for how to download tiles and store them on my device so the application works with no network connectivity at all.
If I missed a similar question in stackoverflow, I apologize in advance.
You'll want to use RMMBTilesTileSource
Check out this example from the folks over at mapbox (also they have a great tool for creating mbtile [sqlite] db's too)

I would like to know whether if there is any Objective-C MSN API. I have searched for a while and could not really find one.
And if not could somebody tell some good place to look to start the protocol from scratch. Some points on how to start with.
I found this site mentioning details about the protocol. But still not sure how to start with.

Thank you and Kind Regards,

I think you might be out of luck. MSN is proprietary so APIS are going to be thin on the ground and those that exist will be reverse engineered.
Having said that, Pidgin is an open source IM client that supports MSN. You could use its core library (libpurple) which is written in C and hence compatible with Objective-C.
By the time you finish reading this question, it will become obvious to you that I'm pretty new to this development. But I've got a quick question here. I think I (unfortunately, sorta) know the answer, but I figured I'd ask, anyway:
I'm working on an app in which I'd like to display traffic data from Google Maps into a map. Easy enough, it seems. I can easily put the a MKMapView and center it on the desired location. I can also create a custom Google Maps API that I can look at on my browser, and it would display the traffic data with the GTrafficOverlay object.
Now...
Can I use the API traffic data (in Javascript) and parse it into the MKMapView implementation? I don't think so... right?
So, my only other option is to do a UIWebView instead, right? I just link to that page, and I'm good to go.
Also... Is there a major drawback to doing that? I know I lose a bit of the built-in interface, but beyond that, it doesn't seem to be that huge a difference, right?
And, also, if I want to use that Google Code API, how do I implement it in place? Do I have to have that HTML file somewhere in a server, or can I have it as part of my resources, or what?
Sorry about all the questions, but thanks in advance for any suggestions y'all might have!
You can't parse the javascript into the MKMapView implementation directly.
Yes you can use a UIWebView. I've only had a brief look at that, and it was pretty nasty with default behaviour, because both the web view and the map view try to respond to drag events etc. There is probably a way of tuning that out - you would want to look for SDK2.x examples as there was no other maps solution then.
This post may also provide a lot of help.
I am trying to use CloudMade's route-me service in my application. All I need from the service is driving distance between two locations, I don't want to display it in a map.
There doesn't seem to be any tutorial in CloudMade's website that handles this. I mailed to the support address they have provided. Nothing back from them so far. Any help from people who done this before would be highly appreciated.
I lost hope with this one, and asked for an alternate option, and found a good solution with CloudMade after all.
