How to call the given javascript properly in below code?
<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>
- (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>";
NSString *result = [webView stringByEvaluatingJavaScriptFromString: jsString];
content = [content stringByAppendingString:result];
[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.

Try this :-
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if(_data)
{
NSString* content = [[NSString alloc] initWithData:_data
encoding:NSUTF8StringEncoding];
[_data release];
_data = nil;
NSString* Html = #" <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>";
//Here to call that javascript
NSString *result = [_webView stringByEvaluatingJavaScriptFromString:Html];
content = [ScriptNotify stringByAppendingString:result];
[webView loadHTMLString:content baseURL:_url];
}
}
