Load Facebook Friends into an NSMutableArray - ios

Question

I am currently trying to load a user's Facebook friends into an NSMutableArray. However, when I use [users addObject: friend.name]; it doesn't add it to the array outside of the block of code. What am I missing here? Also I am trying to receive the number of friends and this also isn't working outside the block of code. What am I doing wrong here?
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
users = [[NSMutableArray alloc] init];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
[users addObject:friend.name];
NSLog(#"%#",users);
}
}];

Answer 1

yes it is added in the array, but we have to wait sometime to complete the block process. I am fetching friends and storing in NSMutableArray. and use it after some delay of time. I am using below code.
[FBSession setActiveSession:[self appDelegate].session];
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
users = [[NSMutableArray alloc] init];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends)
{
NSLog(#"name : %#",[friend name]);
[tempArray addObject:friend];
}
}];
[self performSelector:#selector(afterFetchingFbFriend:) withObject:tempArray afterDelay:10.0];
in 10.0 delay it completes the block process and i have all the friends in my array.
and then my method to process array is :
-(void)afterFetchingFbFriend:(NSMutableArray *)tempArray
{
//do something.
}
if not getting in 10.0 delay time then increase it as it depends on internet speed so the fetching friends time may be different. It works for me.
