i want to measure network traffic of
GPS , 3G and WiFi separately
Application vise separately
in iphone , can any one suggest me the APIs to perform all above task or show me some example or road map.
There's no way to get those figures from the publicly documented APIs (and I don't quite know what you mean by 'network traffic of GPS', because GPS isn't a network protocol). So the answer to your question is: no, nobody can suggest it, because it's not possible within the public APIs.
You can probably do it using undocumented classes or on jailbroken devices, but if you're looking to put your app on the app store there's no point considering that because it will just get rejected.

I'm interested in measuring the network traffic for my application. Ideally I would need to separate wireless from 3G network traffic. I can't seem to find any API that gets this information; however I see that there is at least one app in the AppStore that does something close (they actually sum up the traffic for the entire phone).
Any ideas?
I've found one approximate solution: getifaddrs can be used to get statistics on network usage.
One advantage is that it can get separate statistics for Wi-Fi and WWAN interfaces.
A disadvantage is that on multi-tasking devices those interfaces may be used by multiple applications and the statistics are cumulated.
I also was looking for solution and found it here:
iPhone Data Usage Tracking/Monitoring
Please take a look this post, it provides all info that you need.
I'm just getting started with mobile development, and after considerable searching I'm still confused about sending a message from my iPhone to another or an Android. For instance, in building a simple Tic-Tac-Toe game, if I want to notify the other phone of a move, what is the best way to do so? Wifi, bluetooth, 3G? And how?
Many methods seem to point to communicating through a web server, but I'd rather send them directly from phone to phone if possible. (this is for native apps of course)
If you don't want to have a server (or even if you do! It depends!) it sounds like you will want to use TCP sockets. Apple doesn't have a generic bluetooth API to use with iPhone-to-android communication and you'll have TCP access anyway with 3G. A 3G network connection is very similar to wifi and you should be able to check for the difference as needed with little change to your overall networking code. I'm not sure if bonjour is supported on android, but I bet someone has ported it for similar reasons already, and it is supported in iOS. Apple has a networking section for iOS that you may find informative.
Additionally if you want to stay within the iOS device only realm you could use GameKit to communicate via bluetooth.
Hope that helps some.
The easiest way is to create a web server with an API and the clients poll the server for new moves (or the server pushes the client an update). This is the only way you're going to be able to do it over 3G unless you can figure out the IP addresses of both phones (do phones even keep the same IP address for a long period of time?) and open up sockets between them and let one phone be the server and the other be the client (could cause potential cheating).
WiFi is not always there - by limiting your users' options to areas with access points, you'll lose sales. Not sure about Bluetooth - how prevalent is it on handsets, how much of the API is exposed. Your best bet, IMHO, is 3G. With some kind of a central presence server (Web or otherwise), with optional proxying. Read up on peer-to-peer networking.
As far as i know does the iphone only support incoming messages over push notifications.
This means, that you have to update the information, by requesting it from web services etc.
The bluetooth API of the iphone doesn't support this either.
I want to send some Text plus a image from one iphone application to other iphone app but restriction is I should not use a web server in between communication,Is there any way to fulfill it ?
Details: There are two independent devices and could be far enough say out of network. My requirement one app adds some text with a image and sends it to another iphone which can be at any long distance , and the app installed in another iphone will read that info and image into itself.
Actually there is a solution that meets your needs — and that fits to bbums answer:
Create a HTTP-Server on the iPhone, using cocoahttpserver. than you will ask some webservice like whatismyip.com for your public ip. with this your iPhone can be connected worldwide.
But very likely ur wifi-network is not forwarding your port to the iPhone. Ash.
And even if: Now it gets difficult. How to publish your ip from one phone to the other? hmmm... — I got it: I will exchange the information in a centralized space! In the web!
... wait — that would be a Webserver.
You see: Without any kind of server in the Web the users would need to exchange ip manually and have full admin power and knowledge about the local network.
So IMHO bbums answer is the only way to go.
PS: I am working with http server running on iPhones. In local network that works great, especially with bonjour. And you can use them over distance network — but only with reconfiguration of your router — something you shouldn't force your user to do
There is far from enough information to provide a specific answer.
two apps on two different devices?
are the two devices on the same network?
are the two devices both on WiFi?
do you need the user to receive a notification or something if the app isn't running?
If on same device, you can define a custom URL handler in the destination app and then openURL: in the source app to pass the data over. Encode your image and text into the URL, but be careful of size limitations.
If on different devices, there are many possible solutions, but answering the above questions will be critical to actually knowing what solution is appropriate.
Given your comment -- two apps, different devices, arbitrary networks -- then you are going to have to have some kind of server in between. Note that the recently added Game Center does have the ability to rendezvous two users, but it has a very particular user experience that may not be appropriate to your needs.
I would suggest that you investigate using push notifications to notify the receiving user of the availability of content. As for moving the content between, no direct connection is possible and you will have to have some kind of store-and-forward server in between. And, yes, a web server is going to be the easiest possible solution simply because HTTP is ubiquitous these days.
If there's no network of any kind available, but both parties have amateur radio licenses, then hooking the two devices up to HF packet radios might work.
THIS is super EASY.
I would code up some software that can turn data into modem signal, like the good old dial up modem. The device would actually make those annoying buzzing sounds.
You get the phone number for your friends nearest landline and call him.
He places his iPhone near the phones receiver in listen mode and you connect to his phone using your audible modem.
Bingo, via the power of sounds you have sent data which is decoded on his device and all for the very cheap price of a phone call, there are pretty cheap these days especially if you use Skype.
Easy Way (relatively speaking)
A way two apps on different networks can communicate without setting up a web server of some sort is as follows.
Use an existing third party storage system like DropBox.
Each app would need the login and password for your DropBox. Then both apps can read and write files that the other app can see.
An existing app that does this is a shopping list app called ShopShop.
The app on my phone and my wife's phone both link to the same DropBox account and the app keeps the shopping list synced up when one of us adds something to the list.
Is there a way to figure out the current data network available on iPhone? Whether it is EDGE or 3G?
It works for me even if its doable using core telephony private framework. I am not bothered about app store submission.
I know its very simple to identify whether the user is on Wifi or CellData network. But not able to find a way to identify the network type among edge or 3g?
Pleas also comment if you know a good core telephony documentation/tutorial to refer to.
I've never investigated this, you could try to start from the Rechability
example from Apple
http://developer.apple.com/iphone/library/samplecode/Reachability/
Could someone suggest a tutorial/sample on how an Iphone application can send data to a remote server using Carrier Data Network only? In other words is there a way an application can programmatically force to enable Carrier Data Network communication, use it to send its request to the remote server and switch it back to user specific communication settings.
I am taking this approach because my application needs to send user's personal info to my server and sending it over public WiFi does not sound right. Please let me know if there is better approach to it....
Thanks
Since no one's writing a full answer ...
I don't know if it's possible to detect CDN vs Wi-Fi, although at some level it must be because the App Store is capable of determining such to prevent large CDN downloads. Of course, the App Store app has access to the private APIs; this functionality may not be exposed publicly. (I don't know if that is the case or not, but be sure you do not use private APIs for your app; the store won't accept it.)
That said, think about the use case of your app, and the marketplace. The iPhone OS and the iPhone App Store are more than just the phones themselves -- they're the iPhone and iPod Touch devices. iPod Touches do not have a CDN; they're Wi-Fi only for connectivity.
As Marc W said in a comment, not all Wi-Fi is public, not all public Wi-Fi is free, and you will likely upset a significant portion of your audience -- people (presumably and hopefully) giving you money.
A better solution would be to use SSL to provide encryption of the private data during transport. This is widely available, works over CDN or Wi-Fi, and provides all the security you should need.
If you look at the Apple Reachability example code, you can test for how you would access a host - however I agree with the other posters that you should consider encrypting your data and let your user's determine how they want to connect to the Internet, and not force one form of connection.
