NSJSONSerialization

Question

I have problems with some public json services with serveices formatted this way

jsonFlickrFeed({
        "title": "Uploads from everyone",
        "link": "http://www.flickr.com/photos/",
        "description": "",
        "modifi ... })

NSJSONSerialization seems to be unable to make its work

NSURL *jsonUrl = [NSURL URLWithString:@"http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback"];
NSError *error = nil;
NSData *jsonData = [NSData dataWithContentsOfURL:jsonUrl options:kNilOptions error:&error];
NSMutableDictionary *jsonResponse = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingAllowFragments error:&error];
NSLog(@"%@", jsonResponse);

Answer 1

Using the latest web API I have solved my problem.

For reference, the old web API is: http://api.flickr.com/services/feeds/photos_public.gne?id=xxxxxxxx&lang=en-us&format=json

The current web API is: http://api.flickr.com/services/feeds/photos_public.gne?id=xxxxxxxx&lang=en-us&format=json&nojsoncallback=1

It's done.

I think that NSJSONSerialization can't deal with the jsonFlickrFeed ( ... ) in your JSON code. The problem is that the pure response is invalid JSON (test it here).

So you will have to build a way around this issue. You could for example search for the string jsonFlickrFeed( in the response and delete it or - the easier way - just cut off the beginning until the valid JSON starts and cut off the last character (which should be the bracket).
