    <p>I'm using objectiveflickr to pull a list of images from a flickr.photos.search query.</p> <p>I have it working where I pull in the thumbnail and the large size image, however sometimes an image doesn't have a large size available and so in the app it displays flickr's image unavailable image. I checked what is returned through the flickr API and the URL's are regular flickr URL's, so there's no way to tell if an image will or will not have a large image that way.</p> <p>The only way I can think of doing this is to create another objective flickr delegate and have it do a flickr.photos.getSizes API call and check against each photo.</p> <p>Anyone have any other suggestions?</p> <p>Here's my code:</p> <pre><code>- (void)flickrAPIRequest:(OFFlickrAPIRequest *)inRequest didCompleteWithResponse:(NSDictionary *)inResponseDictionary { int requestedPhotoTotal = [[[inResponseDictionary objectForKey:@"photos"] valueForKey:@"perpage"] intValue]; for (int i=0; i &lt; requestedPhotoTotal; i++) { NSDictionary *photoDict = [[inResponseDictionary valueForKeyPath:@"photos.photo"] objectAtIndex:i]; NSString *title = [photoDict valueForKey:@"title"]; NSURL *photoURL = [context photoSourceURLFromDictionary:photoDict size:OFFlickrLargeSize]; NSURL *thumbURL = [context photoSourceURLFromDictionary:photoDict size:OFFlickrThumbnailSize]; NSURL *photoSourcePage = [context photoWebPageURLFromDictionary:photoDict]; Photo *p = [[PhotoStore sharedStore] createPhoto]; [p setURL:photoURL]; [p setThumbURL:thumbURL]; [p setSource:photoSourcePage]; [p setTitle:title]; NSLog(@"%@ - %@", title, [photoURL absoluteString]); } [self showGallery]; } </code></pre>

    2. COI'm not finished my project yet, but I've redesigned the core data model I'm using. Now I have one entity Photo which will hold details from the photos.photo and another one called FlickrPhoto which will hold details from sizes.size. There will be several entries in FlickrPhoto for each photo, one for each size available on flickr. For what apparently would correspond to your [self showGallery] I'd then select from this entity where the dimensions were in the range I was interested in. The URLs are stored on the FlickrPhoto entity.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
