xcode 4 + phonegap … not update JS upon build?

Question

I've run into a weird issue that has had me scratching my head for the past hour.

I'm working on an iPad app using Xcode 4 and PhoneGap. It's using jQuery. I've put all my JS into a scripts.js file.

Things are working well.

I spend about an hour doing a lot of CSS tweaking. I'd update the CSS file, stop the app, rebuild, and push to the iPad simulator or my iPad. That's been working fine. Every update to the CSS file is reflected on the new build.

I then needed to update the JS file. I couldn't get things to work and then I finally realized none of my JS changes were actually be put into the build. I finally blanked out my JS file completely, rebuilt, and it's still not updating.

The file I'm updated is being updated in the finder in the project folder (I can right-click 'view in finder' and that file is, indeed, updated).

So I'm stumped. Is the xcode compiler caching the JS file somehow instead of grabbing the updated file? Is there a way to force it to grab the updated JS?

Answer 1

I had this same issue with the iOS Simulator, I tried most of the suggestions above with no success, it would not pick up my changes. Later another possible solution occurred to me, which did work:

Delete the app from the simulator. (ie. Click and hold on the icon, then hit the X when it starts to shake, then Hardware Home) Then re-run from xCode.

(NB: "cordova build ios" was also required)

Find the file called copy-www-build-step.sh.

Mine was in [project_folder]/platforms/ios/cordova/lib/copy-www-build-step.sh

In that file, find the lines beginning rsync -a "...

Add -c to the rsync lines, so they ready rsync -a -c "...

copy-www-build-step.sh is the script that copies the files over from www/ to where they go inside the app file. rsync is the unix file copying command they use. Without that -c, rsync just compares the file size on each file and folder and copies them over if the size has changed, and a couple of spaces or quotes don't count as enough of a change. With the -c, it checksums them and compares the checksums, which will catch even the smallest changes.

I think this will work best, because it's not a workaround, it actually fixes the cause of the problem.

Answer 3

I do not have mac right now, but few things to try:

• Try to look at Your project build (or prebuild or something) action where www folder is supposed to be copied.

• Try to change index.html and see if it works.

• Try to copy paste all Your javascript code to index.html script tag

• Try to validate Your javascript (For example: Google Closure Compiler) and see if it has no problems

Answer 4

I'm not sure which did it, but I did the following:

1. Changed an icon value in my MyProject-Info.plist
2. Quit the simulator
3. Product -> (hold option) -> Clean Build Folder
4. Run

Answer 5

Just add a new "Run Script" build phase to your target in XCode and paste this :

touch -cm ${SRCROOT}/www

Answer 6

Nothing solution of above work finally i saw there are two index.html file and .js file in the project created using Command line tool of Cordova

So make changes as below shown under Staging folder
