使用社交框架 Ios 发布分数时出错

Question

这是我发送新分数的方法：

-(void)sendScore :(int) score : (NSString *)uID : (ACAccount *)ac{
    NSString *url =[NSString stringWithFormat:@"https://graph.facebook.com/%@/scores",uID];
    NSURL * strURL =[NSURL URLWithString:url];
    NSDictionary * parameter =@{@"score": @"10000"};
    SLRequest * request =[SLRequest requestForServiceType:SLServiceTypeFacebook
                                            requestMethod:SLRequestMethodPOST URL:strURL parameters:parameter];
    request.account = _accFB;
    [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
        if (!error) {
            NSLog(@"Error: %@",error);
            NSString * str = [[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
            NSLog(@"str: %@",str);
        }

    }];
}

运行时报错：

{
    "message":"(#200) 需要扩展权限：publish_actions",
    "type":"OAuthException",
    “代码”：200
}

如何添加publish_actions？

Answer 1

您可以随时为活动会话请求额外权限。 Facebook建议在您的应用实际需要权限来完成用户发起的操作时请求权限。另外请注意，您不能同时添加读取和写入权限。

这是请求publish_actions 发布活动会话权限的代码-

FB iOS SDK

[FBSession.activeSession requestNewPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
                                  defaultAudience:FBSessionDefaultAudienceFriends
                                completionHandler:^(FBSession *session, NSError *error) {
                                  __block NSString *alertText;
                                  __block NSString *alertTitle;
                                  if (!error) {
                                    if ([FBSession.activeSession.permissions 
                                         indexOfObject:@"publish_actions"] == NSNotFound){
                                      // Permission not granted, tell the user we will not publish
                                      alertTitle = @"Permission not granted";
                                      alertText = @"Your action will not be published to Facebook.";
                                      [[[UIAlertView alloc] initWithTitle:title
                                                      message:text
                                                     delegate:self
                                            cancelButtonTitle:@"OK!"
                                            otherButtonTitles:nil] show];
                                    } else {
                                      // Permission granted, publish the OG story
                                      [self publishStory];
                                    }

                                  } else {
                                    // There was an error, handle it
                                    // See https://developers.facebook.com/docs/ios/errors/
                                  }
                                }];
