With Xcode, we get a simulator (not an emulator), which is good for various level of testing, but in the end you need device for actual testing. I am interested in creating emulator for various iPhone, iPad, and then different iOS versions.
My question is, can we create an emulator for iOS, if so what could be the approach. I am new to the emulator field, i am an iOS developer, so very much familiar with objective c and iOS sdk. I need to know what skill sets are required for this, and how to proceed. Any ebook, website, most welcome. I am not looking for a perfect answer, a good guideline will work.
I don't know how to do this, but I think if you need to do this you need to compile the source code for armv7 or armv7s processors.
Please check these links, I found during my searching iOS Emulator, iOS Emulators

I have a simple question.
I use an old IPhone with ios version 3.1.3 and I have to deliver an app for the ios version 5.0.
Is it possible to build and deliver an 5.0 app to the store without the correct 5.0 device?
Problem is, it isn't really cheap to buy every single ios version device.
I know it is probably necessary to test on a real device, but I only want to know is it theoretically possible do develop and deliver without the device.
thanks for your help

Yes, it's possible. Xcode comes with an iOS simulator that simulates iPhones and iPads running iOS 4.3 and 5.0. However these don't fully match real devices, so you really should be testing on real devices. There's an additional problem that a lot of functionality won't work on the simulator, such as in-app purchases and Game Center. But for basic applications, you can scrape by.
If you're looking to reduce costs, iPod touches are almost identical to iPhones and a lot cheaper, so that's the low cost way of testing on a real device. I would also upgrade your current device to iOS 4 if possible - iOS 3 is practically dead now, so it's better to test on a real device with iOS 4 than it is to try to support iOS 3.
Yes it is possible to deliver an app without the correct version.
I found out, that it is even possible to deliver apps without an iPhone.
even though you can deploy apps without having an iOS device ..or having a device with lower iOS version..
but in future and generally a good advice i will give is to find someone with correct iOS device version(any other version will work too) and get him to try your app using ad-hoc distribution..that way you can get feedback of how your app will perform..
Yes it's possible. You can anyway test most functionality by using the simulator.
With the new Xcode, you don't need the device when you are building for release.
What you need to do is select iOS Device in the menu, then Product -> Archive.
Then you will see the "Validate" and "Submit" options in your organizer.
Today i was going through an website and found something over this iphone and ipad development projects. I had a question whether a developer requires an iphone to actually work with or is there any other simulator type device where we can test it out too.
It would be also great if you can share some docs on getting started.
Thanks.
We have applications that run without a problem on the simulator and crash on the device, so I'd say yes. You might delay it for a bit, and work on the main aspects and buy the device later, but you should have it.
You should start at the iPhone Dev center and depending on your knowledge of Objective C, try some tutorials for it. One of the first tutorials I read about Objective C, and which helped me a lot, is here
You can simulate certain gestures and actions while running the simulator: the developer.apple article is here
You can test many aspects without having an iPad.
There are, however, some that you cannot.
Touch
Acceleration sensor
3G internet
much more
I strongly recommend buying an iPad / iPhone to test the user interface. A PC and the iPad have very different user interaction models, it's hard to create a native feeling app without having an actual device.
You can develop with the iPhone SDK which include an emulator. http://developer.apple.com/iphone/index.action but you would probably be better off having one of the devices if your developing a complex application. For working with Camera's or sensors it's best to have a real device to test you code on.
I dont think there are any devices that run the iPhone system. If there are they are probably illegal.
There is emulator build in XCode.
You dont need a device to run your code etc, but try to test the touch and other sensors in the emulator.
So basically if you are planning on shipping something bigger than helloworld you probably should get the Apple device.
There must be an emulator (I'm not sure, that's a guess), but as with any other development you better have a real device as well so that you have better chances of reproducing problems customers will report.
For iPad development you must have Mac OS X 10.6 Snow Leopard
I intend to write some piece of code for an iPod and an iPhone. so, i'm looking for emulators for those devices.
basically an emulator which will help me test the application I'm writing.
Thanks.
To develop iPhone apps you need to download the iPhone SDK. This includes the tools and libraries to code you applications as well as a simulator to test your code. This tools are available only for intel macs.
You can get the sdk for free here: http://developer.apple.com/iphone/
To test you code in a real iPhone, you will need to join the iPhone Developer Program (http://developer.apple.com/iphone/program/), which is not for free.
Are you talking about writing an application or writing code for your website to display properly on an iPhone?
The former requires a developer subscription with Apple to access their SDK and emulator.
For the latter, there seem to be several emulators out there to test your web site, check out:
http://iphonetester.com/
http://www.testiphone.com/
A Google search for 'iPhone emulator' should find a lot for you.
The iPhone SDK comes with an iPhone simulator that you can use with Xcode during development.
You can download the SDK from http://developer.apple.com/iphone - you need to be a registered iPhone developer, however, although this is free, after which you can use the simulator.
Note that if you want to send your applications to a physical device you need to enrol in the iPhone developer program which starts at $99.
You probably want to actually get an iPhone for that. You'll have to register the $99 but then you'll get the ability to upload apps to your iPhone/pod.
You could also jailbreak your phone/pod and do whatever you want.
There are also apps available that let you transfer stuff to and from your phone in the appstore (at least one free, if I recall correctly)
If you want to do something more with the files than just transfer them to the phone/pod, it's likely that you'll have to jailbreak your phone/pod anyway.
I keep wanting to find a better abbreviation for typing iPod/iPhone. How about iP(od/hone)? Hmm, not better!
Want to write a site for the iphone, but I don't have one and I don't know anyone who has one.
Is there a way to develop for it without having access to one, maybe apple has some sort of sim for this or something.
Anyone know of anything?
An iPhone simulator is included with the iPhone SDK, which can be downloaded for free from here:
http://developer.apple.com/iphone/program/start/register/
Or, if you have the Safari web browser, you can use this for a fairly accurate result:
http://www.testiphone.com/ or http://iphonetester.com/
There's a iPhone simulator for Aptana (should work on any system) and an emulator Apple provides (if you have a Mac). I've not tested the Aptana one. The Apple one is pretty good, but it runs most web stuff much faster than the actual device.
Try buying an iPod Touch. It has most of what you need to test your code to make sure it's iPhone ready.
The simulator is available for convenience but you won't be able to check proper HIG such as buttons or text being too small.
For a quick test, try regular Safari zoomed until the dimensions of viewport are similar to those of iPhone. Safari exists for Windows too :) Moreover, you can ask it to present itself as iPhone (in the Develop menu) and try a couple of sites.
For a serious development you definitely need iPod Touch. You'll need to have a familiarity with how interface, both native and mobile web, works. The SDK won't be able to give you that.
I wonder though what kind of application you are developing. I don't think web-based applications are that useful or bring revenue at this moment.
I'd suggest running VM ware booting up Mac OS...
You'll need an intel CPU though but still, worth it.
See here:
How to load Mac OS Lion in a VM
What are the options for developing iPhone apps?
Currently I've tried to install gnu kit for Linux without success! Too many steps, and at the and I was unable to compile a single app.
The Apple SDK seems to be much more easy, but I don't have a Mac.
So am I missing something?
You need a Mac, no question. You also need an iPhone or iPod Touch to develop on as although the simulator is pretty good, it is not perfect - I have example code that works fine in the simulator but fails on the hardware. The hardware also has to be modified to add development keys to it so there is a certain risk to using a real iPhone - many people testify that it's safe enough but myself I chickened and purchase an iPod Touch for development. Keys also have to be installed on your Mac and integrated into Xcode - and that's tricky enough to get right even with the standard Apple setup. Xcode is free and really quite a decent IDE.
Your minimum requirements are therefore
An Intel Mac running the latest Mac OS. Cheapest option there is a Mac Mini - $599 although you could probably pick up one on Ebay that would work just fine for $400 or less.
An iPod Touch (or an iPhone if you need the camera/phone features for your app) - $229
A developer licence from apple so you can get they necessary keys - $99
To emphasize, you absolutely have to test the code on real hardware and the amount of pain you will go though trying to use anything else but a Mac and Xcode will easily eat the cost of buying a Mac.
Yes, the Mac. It's probably not worth the effort without the tools. Especially without the emulator. Apple designed the iPhone, it runs a version of OSX, and they have made the tools. It's not even like all you need is the complier because you don't have the tools to debug, load and manage the applications.
Check out http://oreilly.com/catalog/9780596155193/ from your local libarary, it says you don't need a Mac, just a jailbroken iPhone/iPodTouch and Linux. I don't know that you can use the SDK to do it, I'm waiting for the 2g jailbreak to even start, but I sure hope I don't need a Mac.
Besides the official MAC you have a project at google code that attempts to make a toolchain for Linux and Windows. iphone-dev This link shows you how to build it.
There's another FAQ site that answers many of the base iPhone development questions like this, which I've found useful. So you might want to check out iPhoneDevelopmentFAQ.com
