fetching yahoo contacts in iphone - ios

Question

I am following this link: https://github.com/yahoo/yos-social-objc for retrieving yahoo contacts.
After providing all the credentials (i.e secret key, consumer key, app id) it is going to browser for login. But after logged in, it's displaying this message:
To complete sharing of yahoo! info with xxxx, enter code xxxx into xxxx
So, I am not getting that where I should enter this code? And how will it redirect to my application.
Any help will be appreciated.

CloudSponge has an iOS widget for its contact importer. Visit our test drive page from your iOS device to see how it works.
I work for CloudSponge, please let me know if you have any questions.

You need to specify your callback url. By default it's "oob" and will give you the verifier code. It will be better if you present your own web view and monitor the verifier code through webview delegates. Here's how you do it.
YOSSession *yahooSession; //instance variable
- (IBAction)yahooButtonAction:(UIButton *)sender {
yahooSession = [YOSSession sessionWithConsumerKey:YAHOO_CONSUMER_KEY
andConsumerSecret:YAHOO_CONSUMER_SECRET
andApplicationId:YAHOO_APP_ID];
// try to resume a user session if one exists
BOOL hasSession = [yahooSession resumeSession];
if(hasSession == FALSE) {
[self fetchSession];
}else{
[self sendRequests];
}
}
-(void)fetchSession{
// create a new YOSAuthRequest used to fetch OAuth tokens.
YOSAuthRequest *tokenAuthRequest = [YOSAuthRequest requestWithSession:yahooSession];
// fetch a new request token from oauth.
YOSRequestToken *newRequestToken = [tokenAuthRequest fetchRequestTokenWithCallbackUrl:#"http://localhost"];
// if it looks like we have a valid request token
if(newRequestToken && newRequestToken.key && newRequestToken.secret) {
// store the request token for later use
[yahooSession setRequestToken:newRequestToken];
[yahooSession saveSession];
// create an authorization URL for the request token
NSURL *authorizationUrl = [tokenAuthRequest authUrlForRequestToken:yahooSession.requestToken];
[self presentWebViewForYahooWithAuthURL:authorizationUrl];
//present it in webview
} else {
// NSLog(#"error fetching request token. check your consumer key and secret.");
}
}
-(void) presentWebViewForYahooWithAuthURL:(NSURL *)url{
_yahooWebView = [[UIWebView alloc] initWithFrame:self.view.frame];
_yahooWebView.delegate=self; //so that we can observe the url for verifier
[_yahooWebView loadRequest:[NSURLRequest requestWithURL:url]];
[self.view addSubview:_yahooWebView];
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
NSString *requestString = request.URL.absoluteString;
if ([requestString rangeOfString:#"http://localhost"].length>0) {
NSRange verifierRange = [requestString rangeOfString:#"oauth_verifier="];
if (verifierRange.length>0) {
verifierRange.location =verifierRange.location+verifierRange.length;
verifierRange.length = requestString.length-verifierRange.location;
NSLog(#"Verifier => %#", [requestString substringWithRange:verifierRange]);
yahooSession.verifier=[requestString substringWithRange:verifierRange];
[self sendRequests];
}
return NO;
}
else{
return YES;
}
}
