Personally I tend to use NSOperationQueue.

See

The AFNetworking library from Gowalla has a nice and easy way to load images in the background. See here

I like to use ASIHttpRequest. It will be something like this.

ASIHTTPRequest * request = [ASIHTTPRequest requestWithURL:url];

[request setCompletionBlock:^{
    NSData * responseData = [request responseData];
    UIImage * image = [UIImage imageWithData:responseData];
}];
[request setFailedBlock:^{
    NSLog(@"Failed to load image : %@", [request.error localizedDescription]);
}];

[request startAsynchronous];

I guess the question is to retrieve image without using NSData. – Yama Dec 20 '11 at 10:52
Why would you want to avoid NSData? (what's wrong with NSData...?) I thought the question was how to load UIImage without blocking. – barley Dec 20 '11 at 12:25
