with the arrival of the vocal indication on IOS 6.
I want to know if is it possible to add this functionality to my app
Thanks,
Yasin
Cloudmade http://cloudmade.com/products/navi-studio has some tools that could help you.
They provide a service that returns a XML representation of the route with turn by turn information included. You could feed this texts into a text to speech engine.

I'm developing an app that will focus heavily on giving users routes and turn-by-turn directions while driving. It is important that they stay within the app during their drive, so I really don't want to make them leave the app and go to the built-in Maps app. I have been doing a lot of research lately on how to include this functionality, and it is widely known that it is not easy, since Apple doesn't include this functionality in the SDK out of the box. It looks like my options are:
For providing routes (and directions) from one place to another
Use a UIWebView and load some web-based maps with JavaScript, and use the JavaScript API to draw a route
Use MapKit or the Google Maps iOS SDK, query for the route sepaartely through an API, and manually draw some kind of path or polyline on top of it.
Use a library that costs money (like MTDirectionsKit)
For providing turn-by-turn navigation
Use a proprietary library that comes with its own maps (like CloudMade)
Is there anything I'm missing here? What are the pros and cons of each, and how should I pick a solution?
Your insight is greatly appreciated. Thanks!
You say that you don't want to "make" the user leave the app and use the built in software for turn by turn navigation as though this is a bad user experience. A bad user experience would be getting forced to use a turn by turn nav from a webView or some API which would not show up as routing information on my lock screen if I lock the phone or cut into other applications to display banners telling me a turn is coming up, for example, while I'm listening to music on my phone. I strongly suggest you launch Apple maps and let the system handle what it is meant to handle instead of trying to build your own turn by turn navigation and heavily limiting the user from the freedom of exiting the application during a drive.
While on the subject of commercial libraries you might what to take a look at other options:
skobbler/telenav sdk - in-app routing and turn-by-turn navigation based on OpenStreetMap (same maps used by Cloudmade and Mapquest). Check out the demos and the licensing plans and figure out if it's the correct solution for you
(they have a Free Tier that might be good enough for your app - and if you go above that tier I think you should be considering monetizing you app)
and that's about it for the time being (besides the options already named): keep an eye out for Mapbox as they could provide an iOS sdk in the near future - with routing and navigation
I agree with Kris' response. Turn-by-turn navigation is probably best handled by the built-in app. However, for displaying a route and ETA on a 2D map, I think I'm going to go with the Mapquest iOS API, which offers this functionality for free. I didn't know this solution was available until today.
I am developing an iPhone application for restaurants. I have used mapkit to show the locations of restaurants. User also have option to see route to a particular location (restaurant) from the current location. I need to add turn by turn navigation in it. I am using google maps and somewhere I read that iPhone does not show turn by turn navigation because that is restricted in Apple-Google contract for maps. Is it really true? If it is, then is there any other way or any 3rd party library, by which I can implement turn by turn navigation?
Thanks in advance

Your best option for navigation is to let the user choose the turn by turn they want:
- Apple Maps using the maps.apple.com
- Google Maps using the maps.google.com
other apps, such as Navigon, Tom tom.
It is a complicated feature and you're much better off not taking responsibility for any shortcomings of services.
Google Maps licence agreement prevents you from doing turn by turn.
Check Drawing a route in MapKit in iPhone SDK
I have already created an application which retrievs information through web service.
Now i thought about making the app read the titles and the user selected content.
Can I use any frameworks which would help me in making the text which I select to be in speech mode ie: It should read the content as similar as Windows speech Engine.
Check out the below link. It'll help you.

Hey, can i scan/take picture of a check and identify the account number and routing number using phonegap on iPhone
Probably not, at least not directly.
You are going to need to look into some opensource ocr software and integrate it into phone gap.
I am working on a iphone apps in which i am storing the voice of users as audio file and want to display in text.
How it will be ...any idea about APIs ??

Have you seen CMU Sphinx ?
Particularly, pocket sphinx (written in C)
While more recognition oriented, it's been used for transcription before, so it will depend on what exactly you need:
Further, have you considered a non-native/local API, i.e. a web service you could call with your voice data, or are you adamant about a native library/API ?
For example, Ribbit has a platform for these sorts of things, and does support transcribing voice to text
"How do I enable voice-to-text transcriptions?
Available as a paid service, voice-to-text transcriptions are automatically available through the Ribbit API. Please use the $25 Free signup credit to try the service."
There is one app that does this already: Jott. The way they do it is to send the file to transcribers in India! (source)
You will have to develop the voice recognition engine yourself I'm afraid. No library that I know of can do this. Apart form that, the iPhone CPU would probably not be powerful enough.
