ASIHTTPRequest-multiple request - iphone

Question

I am developing an app that will request the profile picture URL of some users from Facebook servers, but I don't know how many users I will have (it might be 2 or it might be 20). Should I use ASIHTTPRequest with a loop and a synchronous request, or the API graph (with Facebook SDK for iOS) with a loop?

Trying using ASINetworkQueue. It will allow you to create a queue of ASIHTTPRequests that can still be started asynchronously. For example
- (void)getImages
{
if(!self.queue)
self.queue = [[[ASINetworkQueue alloc] init] autorelease];
NSArray* urlStringsToRequest = [NSArray arrayWithObjects:#"http://www.example.com/image1.png",#"http://www.example.com/image2.png",nil];
for(NSString* urlString in urlStringsToRequest)
{
NSURL *url = [NSURL URLWithString:urlString];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[request setDidFinishSelector:#selector(requestDone:)];
[request setDidFailSelector:#selector(requestWentWrong:)];
[self.queue addOperation:request];
}
[self.queue go];
}
- (void)requestDone:(ASIHTTPRequest*)req
{
UIImage* image = [UIImage imageWithData:[req responseData]];
[imageArray addObject:image];
}
- (void)requestWentWrong:(ASIHTTPRequest*)req
{
NSLog(#"Request returned an error %#",[req error]);
}
