I would like to develop an IOS app to get notification such as title and body from all applications in iPhone. Is it possible to do that?
No it is not. On Android, yes this is possible. But not on Apple. They restrict permissions so that you cannot access that information as a developer.
Every application is given a sandbox, a directory it can use to store data in. If the application needs access to data on the device that isn't located in the application's sandbox, it needs to request the data through a system interface.
App can only read their notifications, other things are possible with Jailbreak.

User can download same application in many device using same apple id? is it written in any document? or is there any restriction on downloading same app ?
If you are testing app in multiple devices in development phase than you have to add all devices UDID in your apple account.
No issue for same appID
IOS paid application sharing we need to block.
Planning to submit paid application in Apple store. Suppose a user brought application and download to Itunes account, then i sync to my mobile device, able to use that.
1.From itunes can we share application ipa to any other user?
2.is there any way to identify which apple id used for downloading?
3.any option for blocking user without downloading from apple store?
Apps bought/downloaded from the app store are linked to the account that download the app. You can there for not just share the IPA.
On a jailbroke device you might be able to remove the security measures that restrict this. But what you are proposing is not possible with official App Store apps.
You cant code to UDID anymore since the update to the iTunes ToS. They are all account bound. In the cases I have tried to share the .ipa file the app data inside that app specific to me did not migrate to the new user
1) Is it possible to watch user's all activities of iPhone through iPhone SDK Programming As Symantec has developed norton online family inwhich user's iphone safari activities are savedin hidden way?
2) Is it possible to handle outside of sandbox environment which has been created using the application we install?
If you're asking if it is possible to actively monitor what websites a user is visiting using the safari browser and have that information to use in you're own app, it's not.
You can't access the data of another application.
I need to build an Store app that can be used to install a few apps that I've developed. I'm planning to do this using in-app purchasing. i.e. the user can purchase the new apps from my store. Is this possible?
No. The iOS security sandbox will prohibit installing any additional apps from your app. Only apps purchased from Apple's iTunes App store can be installed on a customer's device (except for a developers own devices, and a very limited number of beta test users).
You might be able to sell access to web apps, which a user would have to manually clip as web clippings onto their device (they can't be auto installed). But Apple may or may not accept an app which sells those web clippings, so you'd might have to figure out a way to sell them from your web site.
It would ultimately have to link to the app store to do the app downloads. In-app purchasing is just that...in your apps. You can set up a store, but if you want them to be installed as separate apps on the user's phone, you will just have to link to the app store.
Apple most likely won't allow it.
if you are using your "store" app to distribute full apps, instead of just additions to your store app, it DEFINITELY won't pass.
It would be circumventing their distribution system (and 30% cut) and they won't like that very much.
No, your app can't install other apps directly, but you can use an app store url to send your customers to any of your other apps in the app store. There's more info in this SO thread.
It would be a different story if you were working under the enterprise or ad hoc distribution models, in which case you could link to your apps on a web server and install them over the air. But given that you're talking about in-app purchase, it's pretty clear that you're distributing under the standard distribution model.
If your other apps just deliver new content, what you should do is build an universal app that handles all your content and then let the user download new and different content using in-app purchasing. Then you end up with an app similar to iBook, that offers different content, but the same user interface.
One option is to ship your "parent" app with all the content for "children" apps, albeit encrypted. Use in-app purchasing to decrypt "children" content.
