With the release of Adobe's Flash CS5 comes the ability to compile iPhone apps inside of Flash and then export them into .IPA files with the ability to distribute them into the App Store or into Cydia. Weather you don't want to pay Apple's $100 registration fee or you don't have a Mac, this guide will show how you can create your own iPhone app and be able to distribute them on to other devices.

Update: Apple will now let you submit apps built by Flash CS5 into the App Store!

1. Download Adobe Flash Professional CS5. You can either buy it for $699 or get the free 30 day trial by clicking here.

2. Click on File then click on New. Select the option for iPhone OS and click OK.

3. Now there should be a blank space for you to make your flash app. But before you can do this, you must sign your app.

4. If you've signed up with Apple as a developer and payed the $100 sign up fee, you can download your own application signs at the Apple Developer site.

If you are not an official Apple developer, you will not be able to send apps to the App Store, but you can still send them to Cydia. If you are not an Apple developer, download this p12 certificate and unzip it.

5. Now in Flash CS5, click on File, iPhone OS Settings, and Deployment. For the Certificate box, browse for the p12.p12 file. Enter 1234 for the password and browse for the mobileprovision.mobileprovision for the Provisioning File.

<div class=">

6. Select Deployment - Apple App Store under iPhone deployment type.

7. Click OK. Now start developing your iPhone app in flash like any other game. Beginner flash developers may want to watch this video:

Once you're done creating your app, go once again to File, iPhone OS Settings, and Deployment. Then click on Publish at the bottom. This process will take a few moments. Flash CS5 will create an .IPA file of your application which will show up in the default location of My Documents.

9. Now if you had a legitimate Certificate from Step 4, you can submit your app to Apple for reviewing.

If you downloaded the Certificate from Step 4, go into Cydia (you must have a jailbroken device, find out how to jailbreak here). Tap on Manage, Sources, Edit, Add. Type in http://cydia.hackulo.us.

10. Go into the Search in Cydia. Type in AppSync for the current OS on your device. Install it.

11. Now drop the .IPA file from your My Documents folder into iTunes. Click the Sync button and let iTunes put the app onto your device.

12. Test out your app, if everything is working correctly, using WinSCP (Windows) or Cyberduck (Mac) go into the /Applications/ folder on your device and find the folder of your app. Copy that folder onto your desktop, zip it up, and send it to a repository like ModMyi or BigBoss to host it so others may download it.

Great post, thank you very much for the Mobile Provision and P12.. however, a slight problem..
Trying to export the final .ipa, and it comes up with an error, being the following:
"Error creating files.
An attribute or element contains an invalid value in the application descriptor file. (application.installFolder)."

Any ideas?

Hey in light of the banning of Flash Apps on the app store, will these steps still work. Will they know that the apps I've created are in Flash and immediately ban them?

Deadfire55 said... @ August 24, 2010 at 2:25 PM

Apple will probabaly konw that you have complied using Flash and most-likely ban in. But you can still create your app for use on Cydia.

Anonymous said... @ August 25, 2010 at 10:23 AM

That sucks. I have a flash game that I wanted to sell on the app store. Can cydia sell apps?

Anonymous said... @ August 25, 2010 at 10:24 AM

I've heard that Flash complies to C++ and since C++ is allowed for iPhone apps, wouldn't Apple not find out if Flash was used?

Deadfire55 said... @ August 25, 2010 at 2:46 PM

Yea you can sell Cydia apps through a service known as Cydia Store. Go to ModMyi.com for more info on that, they'll put your app on Cydia.

there is an issue between the itunes and the iphone, it says that it cannot sync the app with the iphone.

Any solutions, please?

Anonymous said... @ January 27, 2011 at 7:33 PM

when you get the "Error creating files. An attribute or element contains an invalid value in the descriptor file.
(application.[insert text here])" that means there is an invalid character in the .xml file. open that up and it will probably be a space. Make sure that there are no spaces in any name or line except for the App name. Hope this helps :)

I get a syntax error when I debug the code.
This is what I get:


I have tried everything I can think of, but to no avail. Would the problem be because the version in the instructional video is the beta version?

iphone 5 said... @ July 19, 2011 at 3:49 AM

Apple fans were desperately looking forward for the next iphone i.e. iphone 5 to get launched at WWDC but it didn’t appear in the conference held in San Francisco on June 6. There is no doubt that this delay in the launch of iphone 5 will be Android’s gain.

hmm about the video in the actions
might as well shorten everything up by doing the math. so instead of that huge formula use this one
ball.x += tx * 0.3
ball.y -= ty * 0.3
instead of putting that long script do the math.
