(NSURLRequest *)request navigationType:
(UIWebViewNavigationType)navigationType
{
NSRange range = [request.URL.absoluteString
rangeOfString:@"code="];

if (range.location = NSNotFound)
{
returne NO;
}

return YES;
}

UIViewController,protocols={"UIWebViewDelegate"}}


function init(self,frame)

self.webView=UIWebView:initWithFrame(frame)

self.webView.delegate =self;

self.url=NSURL:initWithString("http://m.google.com")

local request=NSURLRequest:requestWithURL(self.url)

Should not use property on webview

webview:setDelegate(self) should work

self.webView:setDelegate(self)  ,It can't work.
