我从以下

获取访问令牌
    if ([FriendPeekerAppDelegate sharedDelegate].session.isOpen)
        {

        }
        else
        {
           [FriendPeekerAppDelegate sharedDelegate].session = [[FBSession alloc] init];
           [[FriendPeekerAppDelegate sharedDelegate].session openWithCompletionHandler:^(FBSession *session,
                                                                                          FBSessionState status,
                                                                                          NSError *error) 
    {
                // and here we make sure to update our UX according to the new session state
                [self updateView];
            }];


- (void)updateView
{

    if ([FriendPeekerAppDelegate sharedDelegate].session.isOpen)
 {
        accessToken = [NSString stringWithFormat:@"https://graph.facebook.com/me/friends?access_token=%@",
                                      [FriendPeekerAppDelegate sharedDelegate].session.accessTokenData.accessToken];
        if (accessToken != nil)
        {
            self.accessToken = accessToken;
        }

        if ( (callbackObject != nil) && (callbackSelector != nil) )
        {
         [callbackObject performSelector:callbackSelector];
        }


    }
    else
    {

    }
}

然后我想要回复

-(void)getMyInfo
{
FbGraphResponse *fb_graph_response = [self.fbGraph doGraphGet:@"me" withGetVars:nil];
    NSString *tempStr = (NSString *)[fb_graph_response.htmlResponse retain];
    id dict = [[CheckConnectionAndJsonParing singleton]jsonToFoundationRepresentation:tempStr];
}


- (FbGraphResponse *)doGraphGet:(NSString *)action withGetVars:(NSDictionary *)get_vars {

    NSString *url_string = [NSString stringWithFormat:@"https://graph.facebook.com/%@?", action];

    //tack on any get vars we have...
    if ( (get_vars != nil) && ([get_vars count] > 0) ) {

        NSEnumerator *enumerator = [get_vars keyEnumerator];
        NSString *key;
        NSString *value;
        while ((key = (NSString *)[enumerator nextObject])) {

            value = (NSString *)[get_vars objectForKey:key];
            url_string = [NSString stringWithFormat:@"%@%@=%@&", url_string, key, value];

        }//end while    
    }//end if

    if (accessToken != nil) {
        //now that any variables have been appended, let's attach the access token....
        url_string = [NSString stringWithFormat:@"%@access_token=%@", url_string, self.accessToken];
    }

    //encode the string
    url_string = [url_string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    return [self doGraphGetWithUrlString:url_string];
}

- (FbGraphResponse *)doGraphGetWithUrlString:(NSString *)url_string {

    FbGraphResponse *return_value = [[[FbGraphResponse alloc] init] autorelease];
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url_string]];

    NSError *err;
    NSURLResponse *resp;
    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:&resp error:&err];

    if (resp != nil) {

        /**
         * In the case we request a picture (avatar) the Graph API will return to us the actual image
         * bits versus a url to the image.....
         **/
        if ([resp.MIMEType isEqualToString:@"image/jpeg"]) {

            UIImage *image = [UIImage imageWithData:response];
            return_value.imageResponse = image;

        } else {

            NSString *stringResponse = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
            return_value.htmlResponse = stringResponse;
            [stringResponse release];           
        }

    } else if (err != nil) {
        return_value.error = err;
    }

    return return_value;

}
