-------------------------------------
@Patrick
1) Will do.
2) I haven't started to trim the fat from the header, but - we can do that I
suppose, I haven't spent time on it yet.
3) UIWebView uses the WebView somewhere in it's hierarchy, yes. This code
works, I've tested it on an iOS 5 device and simulator. I haven't tested it on
iOS 4 or 3 - I believe this delegate only works on WebKit2 based WebViews, and
iOS 3 probably is based on the original WebKit, but we're abandoning support
for iOS 3 anyway and we can document that this won't work in iOS 3.
4) We could do it like the Location Services permission in iOS, where it pops
up a permission dialog - but users will just have an OK button before they can
proceed. Annoying, yes, but it may be necessary. This will run each time the
app runs.
On another note which may be of interest to you wrt weinre -- what the other
parts of the delegate (that I don't use) suggest, we could build a debugger
with breakpoints possibly... (didExecuteStatement, willEnterCallFrame,
willLeaveCallFrame, etc)

>
> It's possible from tests I did with my proof of concept based on this header:
> http://opensource.apple.com/source/WebKit/WebKit-6531.9/mac/WebView/WebScriptDebugDelegate.h
> You would then set the delegate on a UIWebView subclass that overrode this
> selector:
> {code}
> - (void)webView:(id)sender didClearWindowObject:(id)windowObject
> forFrame:(WebFrame*)frame
> {
> [sender setScriptDebugDelegate:myWebScriptDebugDelegate]; // e.g
> }
> {code}
> webView:didClearWindowObject:forFrame:
> https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/WebKit/Protocols/WebFrameLoadDelegate_Protocol/Reference/Reference.html
> Of course this will involve private methods (not kosher by Apple), and might
> not be baked in (but included in the source that is installed), and we could
> provide instructions on how to explicitly include and enable it and output
> warnings if it is used.
