Problem: I have a webview that is loading a page from Http://somerandomsite-here
before the page is loaded I would like to add in the <head> block a reference to a .js that is in my bundle.
How do I do that?

Found the answer by myself:
NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"js"];
NSString *jsCode = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
[sourceWeb stringByEvaluatingJavaScriptFromString:jsCode];
in test.js place this code in a function that you'll call (see below)
Function setup() { var fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript")
fileref.setAttribute("src", "filename.js");}
when you think it's right do it for you particular case, call this:
NSString *setup = [NSString stringWithFormat:@"Setup()"];
[sourceWeb stringByEvaluatingJavaScriptFromString:setup];

keep in my that this approach doesn't work if you use callbacks in your JS. If anyone knows please fire away!
