How to download image with AFNetworking 2.0?

SO you want something like this for 2.0.

AFHTTPRequestOperation *requestOperation = [[AFHTTPRequestOperation alloc] initWithRequest:urlRequest];
requestOperation.responseSerializer = [AFImageResponseSerializer serializer];
[requestOperation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"Response: %@", responseObject);
    _imageView.image = responseObject;

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Image error: %@", error);
}];
[requestOperation start];

As mentioned by Adam you can also do something like the below if you are just wanting to throw it into an imageView

[myImageView setImageWithURL:[NSURL URLWithString:@"http://sitewithimage.com/images/myimage.png"]];
