推荐答案

在实现FBRequestDelegate和FBSessionDelegate的类中，请执行以下操作:

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];        
 }      

然后调用

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