I am making an app..

I need to download many pictures from a server, but I don't know how to do :(

I try to use this code:

```
UIImageView *image=(UIImageView *)[cell viewWithTag:100];
dispatch_async(dispatch_get_global_queue(0,0), ^{
NSData * data = [[NSData alloc] initWithContentsOfURL: [NSURL URLWithString:@"FileName"]];
        if ( data == nil )
            return;
        dispatch_async(dispatch_get_main_queue(), ^{

            image.image=[UIImage imageWithData:data];

        });
        data=nil;
    });

```

This code is slow... I need to do it more quickly... I think AFNetworking is the best option, isn't it ?
