How to check if a user has granted a certain permission Facebook iOS

In my iOS app, I just want to check if the user has granted the Facebook publish_stream permission.

I'm not sure how to handle the response to the call 

[facebook requestWithGraphPath:@"me/permissions" andDelegate:self];

in my FBRequest delegate method. I've tried:

if (request == self.permissionRequest) {
        NSString *key = [result objectForKey:@"publish_stream"];
        DLog(@"Key: %@", key);
    }

But I get null.

And if I try

    id *key = [result objectForKey:@"publish_stream"];
int keyInt = [key integerValue];
DLog(@"Key: %i", keyInt);

I always get 0. Even when I know the permission is active...

Here's a working sample I did for create_events. Sure it could be used for others:

FBRequest *eventPostOK = [FBRequest requestWithGraphPath:@"me/permissions" parameters:Nil HTTPMethod:@"GET"];
[eventPostOK startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
      BOOL canDoIt = FALSE;
      if (!error)
      {
         FBGraphObject *data = [result objectForKey:@"data"];
         for(NSDictionary<FBGraphObject> *aKey in data) {
             canDoIt = [[aKey objectForKey:@"create_event"] boolValue];
             }
      }
      else
         NSLog(@"%@", error);

      NSLog(@"%@", canDoIt ? @"I can create Events" : @"I can't create Events");
      }];

You can make an FBRequest with the open graph API with "me/permissions". It will return you a response with a dictionary where the key are the permissions. a value will be associated (1 = YES, 0 = NO)
