I developed an iPhone app which I now have to present an audience. For that purpose, I'm creating a presentation with Apple Keynote to show some facts — and after that, I also would like to hold a "live presentation" of the developed iPhone app.
To do that, I need to mirror the iPhone screen (that is, the iPhone running my app) up to my Mac. Best would be, if I could show this "live mirror view" right in Keynote — just as Apple does it in their keynotes.
My idea is to implement a VNC server into my app which mirrors the app to my MacBook which than acts like a VNC client. And at best I would need to show the VNC client's stream in Keynote.
iPhone as VNC Server --> MacBook as VNC Client --> Keynote showing VNC Client's "image stream"
Does anybody knows a good VNC Server framework, which I could implement into my app?
(And if someone has an idea related to the Keynote thing, I would love to hear about that, too.)
Here's something similar, but you'd need an additional television or monitor.

If you're open to jailbreaking you could install Veency which is a VNC server for iOS. Or you could use ScreenSplitr and iDemo which is for jailbroken devices too.
But note, VNC (and possibly ScreenSplitr too) will be laggy. It won't be as smooth as when Apple does it at their keynotes.
An alternate is to look at the possibilities here:
Possible to mirror iPhone/iPad screen on a monitor without jailbreaking?
I have used the google project (http://code.google.com/p/iphoneos-screen-mirroring/) and it worked well for a course demonstration, but nothing that went to the app store.

I would like to minimize the number of devices I would have to purchase to do iPad development so it would be nice if it did :)
I suspect the answer is no because I really doubt apple was kind enough to put an objective c compiler on the device. I guess an alternate question would be what is the cheapest apple platform I could use to build apps?
You are correct. Apple wants you to develop your apps on a Mac.
Here is a link to Apple's site describing what you need. A mac with xcode is a requirement.
No, there is neither a compiler nor and IDE available for the iPad. You need a Mac to do iOS development, but even a cheap used Mac Mini will do (and no, you cannot do iOS development on Windows, I'm afraid).
First to answer your "subject question": As far as I know, NO you cannot install Xcode development kit on an iPad and thereby producing new iPad software... Apple also would like you to buy a real Apple computer if you want to do real business with the platform.
BUT
With some effort and research, you can just buy an orignal Mac OSX 10.6 or newer. Then with some tweaking and fixes, you install this on ordinary PC hardware. This is because the Apple computers today also are running on Intel CPU's and PC motherboards.
Its not officially supported nor "okay" from Apple's licensing point of view, but once you get it running the computer / OS thinks its a real Mac and then you can run and compile Mac software as its running 100% as a Mac.
I've seen tests where the owner connected iPod and iPhones to iTunes and AppStore which didnt see anything unusual, so the owner was able to buy movies and music and applications as normally.
Same goes for installing pure Apple software such as Xcode and other Mac-Only software.
You can even install some boot-manager and be able to run Windows 7 and Mac OSX on a partioned harddrive I've been told.
The "thing" is called a Hackintosh. But I was warned that it is far from every piece of PC hardware that you can make run with Mac OSX, so a lot of studying is needed before succeeding I guess.
I am not sure if this app is compatible with ipad, but it can certainly MAKE your app. You still need the SDK to compile the code it generates, and you still need to purchase the dev program to release your app to the store.
Not to mention the functionality you can add is very limited, but it is the closest to developing on the device itself that you can get.
You could use the Notes app on an iPad, or a Javascript editing app, or a cloud hosted text editor from iPad Safari, to write HTML5/CSS/Javascript for a web app. Upload the resulting web app source text plus a manifest to some web server, go to it in Safari with your iPad, test it, and save it as a web clipping web app.
That's for a web app.
If you want to build native iOS/iPad apps you need an Intel Mac running OS X 10.6.x (but even a cheaper old used Mini or iMac will do, as long as it can run Snow Leopard 10.6).
Or at least fast network access to a Mac. You could remote access a Mac using one of the many VNC or other remote viewing apps for the iPad, and develop native iPad apps from an iPad that way, but it would still involve a Mac.
I've been developing an iPhone web app on a Windows XP box using
MobiOne Test Center and Safari for testing and debugging and
occasionally using a real iPhone for testing. The problem is that
MobiOne, Safari (desktop), and the iPhone all produce different
errors. Obviously I am most concerned with the errors that occur on
the iPhone, since that is the target device. (An example of the type
of error encountered is that an image that ordinarily appears as
expected occasionally cannot be displayed, so the little question-mark
icon appears instead.)
I have the opportunity to obtain a Mac for development, but I need to
know whether using a Mac will make a difference.
Have any of you moved to the Mac for developing or just testing a web-only iPhone app?
Is doing so worthwhile? Why?
Does the iPhone simulator in the SDK simulate an iPhone better than Safari on the Windows desktop?
Is there a reason I would need a paid subscription to the Apple iOS Developer Program?
Thanks!
In short: no, I don't think a Mac is necessary for developing iPhone web apps, especially seeing as you have access to a device to test on, and you seem to be fine in your progress of development.
If you're not aware, there's a debug console available on Mobile Safari on your iPhone. Go to Settings > Safari > Developer (at the bottom) > Debug Console and turn that on.
When developing an iPhone web app, you do not need to pay for the iOS Developer Program. That program is for developing native apps to deploy either to your company or the App Store only.
Web apps, on the other hand, are nothing more than web sites that are designed (i.e. include certain meta tags, have mobile-friendly interface designs) to be run similarly to native apps on a device, and harness certain Web technologies such as geolocation that are available to devices. Users view them in Mobile Safari like any other web site, but for the best experience are asked to tap on the + sign and add your web app to their home screens to be accessed as such.
The iPhone Simulator certainly does a better job than desktop Safari on either Windows or Mac OS X since its user interface shares that of the iPhone device, but I don't think you'll need it for testing and debugging if you have a device to test on.
The iOS SDK has a tool called Dashcode but I don't think it's much of a difference from the web dev IDEs that the rest of us use every day. As far as I can tell, Dashcode doesn't give your web app any additional features that can't already be implemented using the standards we're familiar with.
I would not buy a Mac or a paid subscription to the Apple iOS developer program unless I was writing native iPhone applications.
You should be fine with your current configuration. Just make sure you do the bulk of your testing on the actual iPhone, that is what your customers will be using.
Does the iPhone simulator in the SDK simulate an iPhone better than Safari on the Windows desktop?
Yes - there are some significant differences between MobileSafari and Safari for Mac/Windows - but you've got an iPhone to test on. The iPhone Simulator offers no additional debugging tools for iPhone web apps, so you're not going to be better off having it available than just testing on the device.
Testing on an actual device is better than testing on any of the Simulators, since that is what you mobile customers will actually be using.
If you are strictly building web apps, your money might be better spent on more test devices (devices with and without a Retina display, iPad, maybe an old used iPod Touch running some prior version of iOS for regression testing, etc.) If you are choosy about your colors, the color can vary quite a bit across devices, so it may help to find one warm display and one cold one (from old/different manufacturing lots, etc.).
So you don't NEED a Mac (unless you have other reasons for acquiring one).
Buy an iMac. You will enjoy the experience better.
It is my understanding that your application needs to be compiled on a mac before it can be sold in the app store.
I am creating a desktop version of an iPhone app and would like to have some sort of sync option. The desktop version of the app is an Air app.
I know that I can have them communicate by:
Starting a server on the desktop or the phone
Ask the user to enter the IP of the device into the other one
Make GET and POST requests over the http server
This seems very clunky to me, however, and I would like for them to automatically recognize each others presence when the sync button is pressed. How can this be done between an iPhone and an Air app?
Figured out a way myself: Bonjour
It is possible to implement on the Air side
It is possible to implement on the iPhone side:
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
As the title says, is this possible?
I want to "mirror" my actions on the iPhone so it shows on the computer monitor.
We've seen this on the Apple key notes, but I am not sure if this feature is public.
Many screencasts displaying an iPhone application simply use the iPhone Simulator, which is one option.
You can also take screenshots on the phone by quickly pressing the menu and the power/sleep button at the same time. The image is then saved to your "Camera Roll" and easily transferable to the computer
The other way is only possible with a Jailbroken phone - Veency is a VNC server for the iPhone, which you can connect to with a regular VNC client.
The latest SDKs (beginning with 2.2, I believe), include TV-Out functionality. With a special cable connected to the iPhone dock connector, a program can send RCA signals representing its current screen contents through the iPhone->RCA cable. If you have a TV Tuner for your computer (i.e. I have an EyeTV Hybrid) with RCA inputs, you can display the screen contents of your iPhone directly in the TV viewer.
If your iPhone is jailbroken you can use DemoGod
use screensplitr on jailbrocken iphone/ipod touch it works
Release notes iOS 3.2 (External Display Support) and iOS 4.0 (Inherited Improvements) mentions that it should be possible to connect external displays to iOS 4.0 devices.
But you still have to jailbreak if you would mirror your iPhone screen...

Do not we have an app which can stream the digital movie from iOS devices like iPhone or iPad to be played on a high definition LED or Plasma TV?
I know of an app air video server which can be used to display content played on computer or laptop on iOS device. But is there any app that can do the reverse & play the digital content from iphone to LED tv .
