Is there a way to run a script on iOS?

I need to define a processing rule for web data in iOS and thought it would be a good idea to pull the processing rule as a script file from my server and execute it on the iOS device, since the web API I'm interacting with might change URLs or response syntax and I need to be able to fix such issues fast and cannot rely on pushing an update (takes forever).

I wanted to do it with a small JS file that is pulled from my server every once and a while, but unfortunately iOS doesn't include the JavaScriptCore framework.

Are there other options?

You can compile JavaScriptCore into your app, evidently, and have it approved by Apple. However, as Mehrdad notes, any scripts run in the app must already be in the app at the time the app is reviewed.

You can let a UIWebView run a Javascript snippet, or you could use another scripting language like LUA (don't forget to add LUA for this). The real problem is: You are not allowed to download code from a webserver or somewhere else. Everything must either be already on the device, or calculated at runtime.

Depending on the information that you want, you could use an XML file that includes the new URLs and parse it, but I don't know if this fits your need.

Apple developer agreement will not let you run a downloaded, interpreted script, on the device.

Your best bet is probably downloading a data structure (potentially in JSON format) and parse that and take some predefined actions in your client code based on that, rather than trying to execute the downloaded code directly.
