ios - Facebook scores api with iOS5.1 - Can read scores...但不能发布

Question

我是 iOS 开发的新手，我已经成功地集成了 facebook 登录等...但是我的问题是 Score api。我可以阅读乐谱，但我似乎无法发布它，我拥有 publish_actions 权限，并且正在取回有效的 access_token。不确定是什么问题，这是我的代码 -

NSString *accessTokenToUse = [NSString stringWithFormat:@"%@",[self.facebook accessToken] ];

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   //@"233", @"score",
                                   accessTokenToUse, @"access_token",
                                   nil];
    NSMutableDictionary *paramsB = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"233", @"score",
                                   accessTokenToUse, @"access_token",
                                   nil];
    NSLog(@"APP ACCESS TOKEN: %@",accessTokenToUse);

    [self.facebook requestWithGraphPath:@"me/scores" andParams:paramsB andHttpMethod:@"POST" andDelegate:self];
    [self.facebook requestWithGraphPath:@"APP_ID/scores" andParams:params andHttpMethod:@"GET" andDelegate:self];

***编辑 - 仍然无效

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               @"233", @"score", 
                               @"[APP_ACCESS_TOKEN (omitted for stackoverflow)]", @"access_token", nil];
[self.facebook requestWithGraphPath:@"/[userID]/scores" andParams:params andHttpMethod:@"POST" andDelegate:self];

编辑 - 已解决

所以基本上我传递了正确的 token ，但是 facebook sdk 在 Facebook.m 中将其覆盖为用户的访问 token 。所以修复很简单——每当我需要传递应用程序的 token 时，我只需添加另一个参数p>

- (FBRequest*)openUrl:(NSString *)url
           params:(NSMutableDictionary *)params
       httpMethod:(NSString *)httpMethod
         delegate:(id<FBRequestDelegate>)delegate {

NSLog(@"PARAMS BFORE: %@ ", params);
[params setValue:@"json" forKey:@"format"];
[params setValue:kSDK forKey:@"sdk"];
[params setValue:kSDKVersion forKey:@"sdk_version"];

if ([self isSessionValid]) {
    if ([params objectForKey:@"useAppToken"] == nil || [params objectForKey:@"useAppToken"] == @"no") {
        [params setValue:self.accessToken forKey:@"access_token"];
    }

}
NSLog(@"PARAMS AFTER: %@ ", params);
[self extendAccessTokenIfNeeded];

FBRequest* _request = [FBRequest getRequestWithParams:params
                                           httpMethod:httpMethod
                                             delegate:delegate
                                           requestURL:url];
[_requests addObject:_request];
[_request addObserver:self forKeyPath:requestFinishedKeyPath options:0    context:finishedContext];
[_request connect];
return _request;

请务必在此处注释掉 NSLogs...:)

只能使用应用程序 access_token 发布乐谱，而不能为用户发布乐谱(您可能正在使用它，可以阅读乐谱，但不允许您发布它们)。

引用 Scores documentaion :

Create or update a score for a user
You can post a score or a user by issuing an HTTP POST request to /USER_ID/scores with the app access_token as long as you have the publish_actions permission.
