Question

Problem-＆GT;我只是想取很多不在主队列但在不同队列上的朋友，在队列中我也称为登录，openSession方法进行登录。我想尝试获取分数

第1步 - ＆gt; - （void）requestcallerWithQueue在这个方法中我试图获取由我创建的队列内的得分（不是主队列）然后FBRequestConnection startWithGraphPath：FBRequestConnection中的方法调用startWithGraphPath： NOT RESPONDING 。

步骤2 - ＆gt; - （void）requestcallerWithoutQueue在这个方法中我试图获取由我创建的队列内的得分（不是主队列）然后FBRequestConnection startWithGraphPath：FBRequestConnection中的方法调用startWithGraphPath：回复

          **CODE IS BELOW FOR REFERENCE**


-(void)fetchscoreWithCallback:(void (^)(NSDictionary*))callback
 {

    NSMutableDictionary* params =   [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                 [NSString stringWithFormat:@"%ld", (long)10],     @"score",
                                 nil];

// [NSString stringWithFormat:@"%llu/scores", lintFBFriendId]
    [FBRequestConnection startWithGraphPath:@"245526345633359/scores"
                             parameters:params
                             HTTPMethod:@"GET"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
 {
     NSLog(@"result->%@",result);


 }

}

不工作

-(void)requestcallerWithQueue
{

    dispatch_queue_t some_queue = dispatch_queue_create("some.queue.name", NULL);
    dispatch_async(some_queue, 
   ^{
       [self  fetchscoreWithCallback:callback];
    }];

}

WORKING

-(void)requestcallerWithoutQueue
{

       [self  fetchscoreWithCallback:callback];

}

FBRequestConnection使用NSURLConnection，默认情况下要求调用线程具有运行循环。对于非主线程，您必须自己管理运行循环或将工作分派回主队列。对于某些资源，请查看：

NSURLConnection needs a NSRunLoop to execute?

[FBRequestConnection startWithGraphPath：不使用队列
