I have integrated the iOs Facebook API into my app successfully. Now, I want to get the Friends of the users. To get it I use:
[facebook requestWithGraphPath:@"me/friends" andDelegate:self];
And I implement a the delegate method to recieved it:
- (void)request:(FBRequest *)request didLoad:(id)result {
uids = [[NSMutableArray alloc]init];
if([result isKindOfClass:[NSDictionary class]])
{
NSLog(@"dictionary %@",result);
result=[result objectForKey:@"data"];
if ([result isKindOfClass:[NSArray class]])
for(int i=0;i<[result count];i++){
NSDictionary *result2=[result objectAtIndex:i];
/*NSLog(@"resultq:%@",result2);
NSString *result1=[result2 objectForKey:@"id"];
NSLog(@"uid:%@",result1);*/
Friend *f = [[Friend alloc] initWithDictionary:result2];
[uids addObject:f];
[f release];
}
NSLog(@"uids %@",uids);
}
}
So I create the object Friend with every Friend of the user. I get the friends correctly but with a random order.
The question is, there is any way to receive the user's friends in alphabetical order?

Instead of receiving them in Alphabetical order, why don't you just re-arrange the array of Friends once you have downloaded all of them. This is the best way to compare an array and sort it alphabetically.
sortedArray = [anArray sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];
But if you want to compare the array by an attribute / variable of the Friends class i.e Name, you can do it the following way:
sortedArray = [anArray sortUsingSelector:@selector(name)];
