与Facebook和服务器端验证的ios身份验证

Question

我的iOs应用使用Facebook-sdk对Facebook用户进行身份验证。

现在应用程序连接到服务器并且必须确认用户身份。哪个是推荐的方式？ 可能iphone必须发送某种令牌给服务器，并且服务器必须通过Facebook的api调用确认它

您是否有链接到这些文档？

您好ü要在iOS应用程序与Facebook登录我有使用此代码为它请检查 先取Web视图中你读应用程序，并做护理文件的连接。而输入你的Facebook申请

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 

NSString *client_id = @"Enter your Application "; 

NSString *redirect_uri = @"http://www.facebook.com/connect/login_success.html"; 

NSString *url_string = [NSString stringWithFormat:@"https://graph.facebook.com/oauth/authorize?client_id=%@&redirect_uri=%@&type=user_agent&display=touch", client_id, redirect_uri]; 

NSURL *url = [NSURL URLWithString:url_string]; 

NSURLRequest *request = [NSURLRequest requestWithURL:url]; 

[self.webView loadRequest:request]; 

} 
-(IBAction)getText:(id)sender{ 

NSLog(@"%@",[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"]); 
} 
- (void)webViewDidFinishLoad:(UIWebView *)_webView { 



NSString *url_string = [((_webView.request).URL) absoluteString]; 
NSLog(@"%@",url_string); 

NSRange access_token_range = [url_string rangeOfString:@"access_token="]; 

//coolio, we have a token, now let's parse it out.... 
if (access_token_range.length > 0) { 

    int from_index = access_token_range.location + access_token_range.length; 
    NSString *access_token = [url_string substringFromIndex:from_index]; 

    NSLog(@"access_token: %@", access_token); 
    htmldata=[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.outerHTML"]; 
    NSLog(@"%@",htmldata); 
    NSLog(@"%@",url_string); 
    NSArray *arr1=[htmldata componentsSeparatedByString:@"<title>"]; 
    NSString *data=[arr1 objectAtIndex:1]; 
    NSArray *arr2=[data componentsSeparatedByString:@"</title>"]; 

    value=[[NSString alloc]initWithString:[arr2 objectAtIndex:0]]; 

    NSLog(@"%@",value); 
    if([value isEqualToString:@"Success"]) 
    { 
     MainScreenController *C = [[MainScreenController alloc]init]; 
     [self.navigationController pushViewController:C animated:YES]; 
     [C release]; 
} 
} 
}
