Mobile Development with Phonegap / Cordova

Part 1 (again): Getting set up for iOS development on OSX


Last week I got my development environment set up for Android: Windows 7, Eclipse, and Phonegap/Cordova. I also got my iBook and set up Xcode, and got the demo app running on iOS. And here's the writeup.

Some if it may be a bit brief, as  I'm presuming you read my writeup about Android, where I describe some synonyms and terminology.




THE STACK

The way to use Cordova (aka Phonegap) to build iOS apps, is to use Xcode on a Mac. The basic stack is:

- A Mac. It must be running Mountain Lion (OSX 10.8) or later.
- An Apple ID so you can use the App Store
- Xcode 4.x
- Phonegap and its create script
- Your iOS device, or the built-in simulator

In fact, it is a violation of the iOS Terms Of Use, to develop an app for iOS not using Apple hardware and authorized tools. So this stack really is it. (comments about Microsoft and the anti-competition lawsuits of the late 1990s, tastefully deleted)

In my case, I hit up eBay and found a used iBook running Mountain Lion for $400.



GETTING AN APPLE ID AND IOS DEVELOPER LICENSE

If you want to deploy your mobile app via the App Store, you will need to extend your Apple ID with an iOS Developer License. This means visiting Apple's website (https://developer.apple.com/programs/ios/) and spending a half hour or so entering your information a few times. It also means spending $99 for a one-year registration as a Bona Fide Developer. (must fight... must not make... snarky comment)

This step is optional, required only once you're past the testing phase and want your app to be available to others.



INSTALLING XCODE

Fire up your Mac, open the App Store, so a search for Xcode. It comes right up, and a few clicks later it's downloading and installing. It's really that painless.

This is a 1.6 GB download, so on household DSL it took overnight. On a cable modem, you'll still have time to catch dinner and a couple episodes of Futurama...

After it's set up, start Xcode and then install the Xcode command-line tools: Preferences / Downloads / Components As long as I was there, I also had it grab a bunch more documentation and libraries. The whole shebang was another 1.1 GB, but again went painlessly.





INSTALLING PHONEGAP (CORDOVA)

Do a Google search for "phonegap download" and download the Cordova library. The version 2.2.0 is about 26 MB, and downloads in a few moments.

The Phonegap library doesn't really "install" but you extract it someplace. On my Mac (Mountain Lion, Safari, very default configuration) the Cordova library unzipped, leaving me a folder. I simply moved the folder into my Documents folder, and renamed it to phonegap



SET UP A PROJECT

Open up a Terminal (use the Spotlight, the magnifying glass, and type "terminal". The icon is a black square) and run these commands:
  • ./Documents/phonegap/lib/ios/bin/create FOLDER_PATH PACKAGENAME PROJECTNAME
  • Close the terminal
 FOLDER_PATH - This is the path to the intended folder for your new project, e.g. ./Documents/MobileApps/WalkTracker
PACKAGENAME - A dotted-format app name combined with domain name, e.g. org.greeninfo.walktracker
PROJECTNAME - The name of your app as you want it to appear, e.g. "Walk Tracker Calorie Counter"
Example (don't forget those quotes!):
./Documents/phonegap/lib/ios/bin/create./Documents/MobileApps/"Walk Tracker" org.greeninfo.walktracker "Walk Tracker Calorie Counter"
This will create a new folder, containing an Xcode project file.



RUN IT!

Open up Xcode and load that project file (or, simply open the project file).

In the upper-left is the familiar arrow button indicating Play. Pick your iOS simulator version, click the button, and there's your demo app.


CONCLUSION

Unlike Windows / Eclipse / Android setup, this one was a snap. Most of my time wasn't spent researching errors, but periodically checking a download bar. The create script ran without issues, and aside from download time I had the demo app running in 10 minutes.

The official version of this setup process is at Phonegap's own website. It's actually really accurate, and I admit that I had little to add except for narrative. (that's a compliment, Phonegap developers)

NEXT STEPS

My goal for today (a break, on account of Veterans' Day) is to sit and play with both platforms and get a basic mobile app running. I have only vague ideas as to what it will do, but that's not the important part just yet. :)
