ios - 如何获取访问令牌？

Question

我正在关注this link以获取访问令牌，但有些漏洞在下面的代码中，特别是在网址和内容中。

-(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>"; 

    //Here appending the above javascript with content 

    content = [jsString stringByAppendingString:content]; 

    NSURL *url = [[NSURL alloc] initWithString:@"https://converse.accesscontrol"]; 

    [webView loadHTMLString:content baseURL:url]; 
    } 
    } 

当登录到Gmail或Yahoo，下面的代码将被解雇，然后检查URL，但在这里（如果条件不满足）。如果你能不能够明白，我想要问。请参阅上面给出的链接。

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

{ 

_url = [[NSURL alloc] initWithString:@"https://converse.accesscontrol.windows"]; 

    if(_url) 
    { 

    if([_url isEqual:[request URL]]) 
    { 
     return YES; 
    } 

    [_url release]; 
    } 

    _url = [[request URL] retain]; 
    NSString* scheme = [_url scheme]; 

    if([scheme isEqualToString:@"acs"]) 
    { 
    // parse the JSON URL parameter into a dictionary 
    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; 

    } 

任何想法？提前致谢。

你有成功的设备令牌.....
