ios - How to append javascript with HTML content? - iphone

Question

I'm trying to get access token,I'm following this link to get that,but some condition fails,I think am not properly append the javascript with HTML content.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if(_data)
{
NSString* content = [[NSString alloc] initWithData:_data
encoding:NSUTF8StringEncoding];
[_data release];
_data = nil;
NSString *jsString = #"<script type='text/javascript'>\
window.external =\
{\
'Notify': function(s) { document.location = 'acs://settoken?token=' + s; },\
'notify': function(s) { document.location = 'acs://settoken?token=' + s; }\
}\
</script>";
content = [jsString stringByAppendingString:content];
[webView loadHTMLString:content baseURL:_url];
}
}
- (BOOL)webView:(UIWebView *)webView
shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType
{
if(_url)
{
if([_url isEqual:[request URL]])
{
return YES;
}
[_url release];
}
//Here am getting http://LoginSuccess.aspx
_url = [[request URL] retain];
NSString* scheme = [_url scheme];//Here am getting http
//So here condition fails
if([scheme isEqualToString:#"acs"])
{
// parse the JSON URL parameter into a dictionary
_url = [NSURL URLWithString:#"https://converse.accesscontrol.windows"];
NSDictionary* pairs = [self parsePairs:[_url absoluteString]];
if(pairs)
{
WACloudAccessToken* accessToken;
accessToken = [[WACloudAccessToken alloc] initWithDictionary:pairs];
//[WACloudAccessControlClient settoken:accessToken];
[self dismissModalViewControllerAnimated:YES];
}
return NO;
}
[NSURLConnection connectionWithRequest:request delegate:self];
return NO;
}
Any ideas? Thanks in advance.

I´m not sure if i unterstand exactly what you´re trying to do, but I assume
[UIWebView stringByEvaluatingJavaScriptFromString:#"yourJavaString"];
could help. I use it to perform an JavaScript based Loginmechanism in one of my projects.
See the Apple doc here .
You have to use stringByEvaluatingJavaScriptFromString AFTER WebView has loaded.
