基于PIN码时，如何在Nest Thermostat中存储授权代码

Question

I am trying to implement Nest Thermostat in My Application i Can success fully create pin authentication code but

--->i struck in while storing that pin authentication code because after checking if condition if ([[url host] isEqualToString:[redirectURL host]]) then,

--->always condition fails if condition success then only i can store it and get access token by using it (as per library)

I did as per Nest Sample code and Library and online solutions no use I am looking for Picking hands

Plz Ref-fear my code

    - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{

        NSURL *url = [request URL];
        NSURL *redirectURL = [[NSURL alloc] initWithString:RedirectURL];

        if ([[url host] isEqualToString:[redirectURL host]])
        {
            NSString *urlResources = [url resourceSpecifier];
            urlResources = [urlResources stringByReplacingOccurrencesOfString:QUESTION_MARK withString:EMPTY_STRING];
            urlResources = [urlResources stringByReplacingOccurrencesOfString:HASHTAG withString:EMPTY_STRING];

            NSArray *urlResourcesArray = [urlResources componentsSeparatedByString:SLASH];

            NSString *urlParamaters = [urlResourcesArray objectAtIndex:([urlResourcesArray count]-1)];

            NSArray *urlParamatersArray = [urlParamaters componentsSeparatedByString:AMPERSAND];
            NSString *keyValue = [urlParamatersArray lastObject];
            NSArray *keyValueArray = [keyValue componentsSeparatedByString:EQUALS];

            if([[keyValueArray objectAtIndex:(0)] isEqualToString:@"code"]) {

                [self.delegate foundAuthorizationCode:[keyValueArray objectAtIndex:1]];

            } else {
                NSLog(@"Error retrieving the authorization code.");
            }
            return NO;
        }
        return YES;
    }

使用基于Web的身份验证并在注册客户端时填写重定向URL，此重定向URL在客户端页面上不应为空，然后，一旦将设备登录凭据输入到应用中，它就会自动重定向并提供身份验证令牌，然后将提供带有该身份验证令牌的访问令牌，通过使用该访问令牌，您可以获得设备详细信息
