FBRequestConnection not working

问题

Nothing gets printed out in the console, and I don't get any info while using a - (void)request:(FBRequest *)request didLoad:(id)result either

Basically I would like the user's name, FB username, and FB id. Is there any other way to get this info, since this method does not seem to be working.

- (IBAction)performLogin:(id)sender
{
    [self.spinner startAnimating];

    GIFAppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
    [appDelegate openSession];
    FBRequestConnection* conn = [[FBRequestConnection alloc] init];
    [conn addRequest:[FBRequest requestForMe] completionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *me, NSError *error) {
        if(error) {
            NSLog(@"Error requesting user info");
            return;
        }

        NSLog(@"User's name is %@", me.name);
    }];
}

Note that the rest of the method works, just not the FBRequestConnection portion of it. :)

回答1:

I believe you have just started using the new graph SDK:

Here is how you can pull out some of the info:

// Your Info:

[FBRequestConnection startWithGraphPath:@"/me" parameters:nil HTTPMethod:@"GET" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    NSLog(@"result %@",result);
}];

// Your Friends Info

   [FBRequestConnection startWithGraphPath:@"me/friends" parameters:nil HTTPMethod:@"GET" completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
        NSLog(@"result %@",result);
    }];

And similarly, you can pull out more information. You should read about more graph objects - here. This is how you will get to know, what all things you can pull out. Also you can query on facebook using FQL.

Hope this helps.

Add the following line after adding the request:

[conn start];

回答3:

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


dispatch_queue_t some_queue = dispatch_queue_create("some.queue.name", NULL);

dispatch_async(some_queue, ^{

    // [NSString stringWithFormat:@"%llu/scores", lintFBFriendId]

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

I wanna Fetch Scores but when i put [FBRequestConnection startWithGraphPath: in a queue but it doesn't response or print data if i remove queue it works
