为什么我的nimbus didImageLoad方法没有被调用？

Question

I'm new to Nimbus. Right now my app is trying to retrieve 4 images via this code:

for (int i=minFoto; i<=maxFoto; i++) {

    NINetworkImageView* networkImageView = [self networkImageView];

    NSString *resourceURL = [NSString stringWithFormat:@"%@registration/rest/users/account_get_foto/%@?fotoId=%d", baseURL, ssid,  i];

    NSLog(resourceURL);

    [networkImageView setPathToNetworkImage:resourceURL
                             forDisplaySize: CGSizeMake(50, 50)
                                contentMode: networkImageView.contentMode];

I know my loop is working because I see all four NSLog's come out correctly. However, I am only getting the first image. networkImageViewDidStartLoad is only being called once and neither didLoadImage or networkImageViewDidFailLoad is being called. I think it is odd that didLoadImage is never being call. Never. I know I have the data because I'm using CharlieProxy (great app BTW, well worth the $50) and it shows the image data in the response packets.

So I commented this out of my delegate:

[[Nimbus networkOperationQueue] setMaxConcurrentOperationCount:1];

And as you might expect, I'm getting 4 calls to networkImageViewDidStartLoad, and still zero to didLoadImage or networkImageViewDidFailLoad.

Here are my request headers (from CharlieProxy)

GET /registration/rest/users/account_get_foto/fdbc2222-7b75-4ff4-b111-623e951e5b00?fotoId=134     HTTP/1.1

and here's the response headers, showing a "200 OK"

I'm a little puzzled now. My server is clearly returning the image data, but my app just isn't getting it. Any ideas?

Well, I found it. Might as well put the answer in for future googlers.

My networkImageView had gone out of scope and was ARC'd. Funny, I thought I had saved it away, but that code was partially commented out!
