This answer helped me: Prevent caching of .css files in UIWebView loaded from disk

Basically, you just need to add an incrementer as parameter to the link like ?version=1 or ?time=12345678. For example: <script src="myscript.js?version=123></script>

For a dynamically loaded javascript I'm using:

script.src = "myscript.js?version="+new Date().getTime();

and the script is updated properly, without the version parameter the file is cached in the UIWebView.

I suspected UIWebView caching as well. Initially. But the actual problem was with Xcode treating .js files as pilable sources - Xcode puts them into a "Compile Sources" build phase (project targets -> Build Phases tab) whereas they should be in "Copy Bundle Resources" phase. Whatever piler think about the .js file, it does not detect the change and replace it when changed. Moving my .js file from pile phase to copy resources phase fixed the problem nicely.
