how to retrieve friends' list using facebook connect with iphone app

Question

Hi, I'm using facebook connect for my iphone app. It is able to authenticate the user and also publish a comment on the user's wall. But I'm not sure how to retrieve the user's friends list. A sample code will be highly appreciated.

Thanks in advance,

Answer 1

In a class that implements the FBRequestDelegate and FBSessionDelegate do this:

-(void) getFriends{
        NSString * funcName = @"friends.get";
        [[FBRequest requestWithDelegate:self] call:funcName params:nil];
}

- (void) processFriendsQuery:(id) result{
   friends = [[NSMutableArray alloc] init];
    NSString * element; 
    gDatabase.userIdList = [[[NSMutableArray alloc] initWithCapacity:MAX_FRIENDS_LIST] autorelease];     

 for (element in result){
    Friend * aFriend = [[[Friend alloc] init]autorelease];  
     NSString * uid = [self dictionaryToUID:element];
     aFriend.userId = (NSMutableString *)  uid;
     [gDatabase.userIdList addObject:aFriend.userId];        
 }      

and then call it in

- (void)request:(FBRequest*)request didLoad:(id)result {
  [self processFriendsQuery:result];    
}

Use this method to call ur getFriends method - (void)request:(FBRequest*)request didLoad:(id)result
