I want to make my iphone run application in the background.I know there is a program called "backgrounder",but it isn't I want.What should I do?
This is flat out not allowed... period.
You may want to look into the development community for jailbroken phones. I think there are projects like that there, although you are severely cutting off your userbase.

I am an iPhone developer, I am doing a project. For security reasons, I must make sure my app run on a no jailbreak iPhone. I want to know how to check it use public API.
Thanks very much!
No API exists to perform such a check.
Jailbreaking a device (using any of the various forms of jailbreaking) only needs to touch files which are outside an application's sandbox. Attempting to inspect them therefore carries a risk that your app will be rejected. Even if you can inspect them you have no way to differentiate a change due to jailbreaking from a change due to an OS update.
Finally please be aware that a jailbroken device does not necessarily mean the user has pirated your app. Users of jailbroken devices are free to purchase and install apps via iTunes just like anyone else and are likely to be rightly unhappy if your app refuses to run.
also, Apple removed the API for detecting jailbreaking. Read here on ars
If that would be possible using a public API, there wouldn't be any problem using jailbreaked iPhones, would there. Every app (including the OS) could just use that API...
It's impossible to verify that your app is running only on a non-jailbroken device. Unfortunately there's nothing you can check.
There are a few tricks you can use to determine programmatically if your app has been pirated, but they're far from foolproof; the most you can really do is determine if your app was pirated using the most common automated pirating techniques. Anyone really determined to pirate it can ensure your app doesn't know it's been pirated even if you use the techniques.
I wouldn't invest time in such things cause sooner or later "they" will find a way to run your App on a jailbreaked iOS device.
Instead take this time and develop more unique feature. Feature people are glad to have and even they pirated your App they will pay for it.
Yeah I know this sounds ridiculous but I think quality software will find honest buyers.
I know this answer doesn't answer your question and I want to add that iOS doesn't have a API to check if the device is jailbroken.
I hope I could help.
As the other answers say, there's no full-proof way of blocking piracy on your apps. I have a couple of apps that have been pirated and, truth be told, I was kind of happy to see that. Unless these people hack every single app on the App Store, it made me feel a little proud that someone had decided my apps were worth pirating. Almost a "yup, I've made it" kind of feeling. :)
I am working on a project where the iPad will be used for a specific purpose, and only run one app. When the device starts up, I want my app to run, and I want to override the home button so that it does not quit the app (like the iPhone/ iPod demos in the store).
I have seen bits and pieces of this functionality, but am unsure how to implement it. I realize that it would have to be on a jailbroken device, and the client is fine with that.
Any ideas?
Thanks!

Edit 1: I found this site, which explains some iOS daemons. I'm still researching, so I'll just keep posting what I find.
Edit 2: I found Saurik's IRC channel and asked around in there. One of the participants told me that it is possible, but probably not as simple as I thought. I am still doing some digging around in the iPhone 3G filesystem now just to get the feel of what certain things do.
The project has been scrapped, but I'm still looking for help on this though....just cuz I'm interested lol.
Here's my progress on the issue. Question's still not completely answered, but I'm making some headway :-)
I've been researching Jailbreak and the iOS filesystem as well. That has helped my understanding of the issue some.
Without jailbreaking this would not be possible.
There has to be something in /etc somewhere that runs through all the things that start up, just like on Linux.
It so happens that my current ipod touch has a WALD screen after me manually deleting a few mp3 files. Some anti mp3 mocking code policing it, and not liking me touching the mp3 file structures... otherwise I'd look for you right now.
Do you know how to ssh into your ipod/iphone?
Well, I believe Apple itself uses this on the iPads running at the Apple Stores (those showing animations about the products where you can ask to talk with a blue shirt).
I would look for something on the official IPCU (iPhone Configuration Utility) to check if there is an option for auto-loading apps on boot time.
If not, try to get friends with someone working on an Apple Store and get some hints on how they run their app on those iPads.
you can add the "voip" key in the information plist.
This is backed up by Apple:
You can also see this sample project:

PB.
Not considering legal issues I would be very interested if it would be possible to run one of those on the bare metal of the iPad/Phone ARM-Architecture.
Squeak is running on the iPad as of today!
Considering that iPad has already been jail-broken, I think it's really possible. Also, being made with an ARM processor makes it even more plausible, you already got compilers for that architecture and there seem to be ports of squeakvm to it. It would require some work though.
I know how to get it done, if that helps: send an iPad and a million bucks to Tim Rowledge!
Edit: Someone's got Android working on an iPhone, which is a pretty big step towards a SqueakNOS. In particular, I imagine if you figure out how they do the bootloading, and how to get the image on the phone, you're pretty much there?
Edit #2: Andreas Raab's ported Squeak to Android, so as an interim step one could always run Squeak on Android on the iPhone.
I think it's a silly attempt. The charm of an iPhone, the thing that distinguishes it from Android is that it's a controlled environment. John Gruber calls it an app console. You can find that silly if you want, but remind me again why out of the two major mobile platforms, you choose to breach and extend the one that does NOT brag about its openness and clear documentation and freedom for third party developers. PharoNOS on Android sounds like fun, PharoNOS on the iPhone sounds like PharoNOS on a Wii. That is: You could do it, but why would you?

Possible Duplicates:
How can I develop for iPhone using a Windows development machine?
I'm looking to build an iPhone app for my wife's phone, but am not interested in buying a Mac as a development platform for a one-off piece of work. The app:
should run standalone on the iPhone (i.e. without network connectivity)
would be perfectly acceptable with a GUI created using one of the iPhone Javascript libraries that are around
will do some database IO to read and update data
has no commercial value and will never be used by anyone else
Here's my thinking:
jailbreak the iPhone
install Ruby + Sinatra on the iPhone
write the app using Sinatra, hitting a database (SQLite?) on the iPhone
To access the app on the iPhone:
start the Sinatra app in the
background (is this possible?)
start a Safari browser session
navigate to the Sinatra app at e.g. http://localhost:12345
etc.
This seems like a strange approach, but I can't think of a simpler way of writing a standalone iPhone app without buying a Mac. Is there a better way of doing this?
The only reliable info I could find is at the always-excellent MetaFilter
http://ask.metafilter.com/110466/Anyway-to-develop-iPhoneiTouch-apps-without-investing-in-a-Mac
The answer is apparently no.
You absolutely need an Intel Mac of some description.
The entire iPhone build process is too deeply ingrained in XCode to build elsewhere; and the only other Objective-C compiler I know is gcc, which doesn't support any Apple's additions to the language (nor their libraries).
And, in direct opposition to what people are saying above, Objective-C is absolutely my favorite native, compiled language. Elegant, small (only a few changes from C), late-binding, dynamic, straightforward. It's what C++ should have been.
Lots of people recommend picking up a secondhand Intel (remember, must be Intel!) Mac Mini as the cheapest "port of entry".
What you have described is a viable solution, however you should consider using the open toolchain for the iphone.
You don't need a mac then, only need to jailbreak the phone to make sure your app will work.
For all those who say it can't be done, this was the only way to make Apps for the iphone before the SDK was out :)
Also if you are after a guide to using the open toolchain then I highly recomend this book
If you're considering creating a GUI using a javascript library anyway, why don't you just write a web app instead of an iPhone-native one? It seems like overkill to jailbreak the device just so that you can install a ruby + sinatra web app on it. Can't you just put the ruby web app on a server and create a Safari shortcut to it on the home screen? If you don't have a server, you could always run the website off a PC in your home...
Jailbreaking the OS and running a ruby app onto it would be technically cool, don't get me wrong - I just think it'd end up being a time sink.
Just my 2c!
Depends on what your time is worth, I guess. That seems like a terribly convoluted way to get what is otherwise a simple app on the phone to avoid the US$400 purchase of a used Mac Mini.
There is the hackintosh route, which may work on your existing hardware, but again one has to put a price on time. It's what got me started before I dropped big coin on a Macbook Pro, an MSI Wind then a home-built. It's of questionable legality (the right thing to do is fork over US$129 for Leopard regardless), but you are already talking about jailbreaking. :-)
Get someone else to do it, or rent the resources that you need.
Another option is to find nearby iPhone developer who has it all setup and either get him to write the app or do it together, he provides development environment you code the solution or code it together.
The only problem is that you wont be able to update maintain it.
I would still consider getting older gen Mac or Mac mini - all the other options sound more complicated.
If you are going to be stubborn about not using a mac, but you want an app that will work offline with the iPhone / iPod Touch and Android devices, then I would use HTML 5 to create an offline app.
You can do a lot now with HTML 5 - Google have an email client that uses HTML 5 for the iPhone now and it can work offline etc. If you do this and get the user to add a bookmark to their home screen for your app - it will be almost as good.
If I was you I'd fork out for a mac - or look to see if you could borrow one - or time-share with someone - you will not create a very good quality app without it.
You can jailbreak the phone and install Python. There are some sample applications in Cydia for it (it's called iPhone/Python. Search for Python in cydia).
Then you will have a "native" app, not a web application and you can use the entire iPhone UI library (the part of it that is accessible via py-objc anyway) and you don't need to run a web server in the background.
You can do your development on the phone itself via SSH or you can use an iPod Touch for it. Packaging is also easy (should you need it), just create your own Cydia repository and host your package(s) in there.
Look at iPhone applications in Python for more information.
Come on, just look on eBay for the cheapest intel mac mini you can find. Even a Mac laptop with a busted screen (that you could hook to an external display) would work. You're talking just a few hundred dollars probably and then you can maintain it as her phone/Touch is upgraded.
there's some special meta tags you can put in a webpage to make your web app savable and full screenable to the iphone hard drive. (so it can work offline) Here's an example : http://mrgan.tumblr.com/post/125490362/glyphboard2
There's also frameworks like phonegap that let you access cocoa apis from javascript, but it sounds like you don't need that.
Does your wife enrolled in any kind of data plan? If so, you can simply write a small webapp which runs on some cheap webspace and access it via MobileSafari.
If you need a full grown iPhone application, you better look after one of the first intel-based mac minis on eBay, should be to expensive, in my opinion. And as a plus you avoid the hassle of a jailbreak.
Can you show me how to deploy/debug and iphone application using xcode but without having to pay 99$. I'm doing this for the study purpose.
I've seen a guide which help to deploy iphone application to iPhone device(e.g: http://www.vinodlive.com/2009/01/16/how-to-deploy-an-iphone-application-without-an-idp-membership/). However this guide doesn't help me to run/debug the application using Xcode, so it's quite inconvenient.
Some of my friends said that it's possible to run/debug iphone app to iPhone device using XCode and without IDP membership.
Thanks in advance.
If you intend on developing for the app store ever, I would pay the fee. If you can write, and get accepted, a halfway decent app, you'll have little trouble earning back that 99 bones of initial investment.
I wouldn't wait ~two weeks to have an app reviewed for the store if it had only been tested on a jailbroken iphone using some hack. Too risky...
Apple designed the system the way they did to protect developers from piracy. It's inconvenient because you're not supposed to do it.
I'm not trying to say that you're doing something wrong or illegal, but you're just trying to bypass something that is in place to stop app-theft :)
While not really a good thing, your best bet may be to jailbreak your phone. This will void your warranty and I'm pretty sure a kitten somewhere will die because another iPhone has been jailbroken.
Your stated goal is to debug on a device using XCode without paying $99 to Apple:
Assuming it's for quasi-official study purposes and you can find a cooperative university instructor to sponsor you or undertake some kind of directed study, you could try the iPhone Developer University Program.
It's 'free,' but my guess is that the required hoops and time would make the $99/year for the regular program seem pretty reasonable. (I think the same goes for any jailbreaking solution, but I do remember what it was like to have neither a salary nor any competing demands on my time).
