Is there a way to automatically put in a tag in the box or call on a specific RSS stream.

I am trying to do an App for my Cousin, where anyone can just pull in the latest photos from the wedding.

You are authentic guru guy!!

I’m having trouble figuring out what is causing an “Object value expected for key: venues” error when I attempt to parse a JSON file[1] in my iPhone app. I have created a schema[2] for my JSON file and it passes a check with kwalify[3] so I know the JSON itself is OK (I have found this validator is very picky). One thing that I do notice is that the JSON file in question here is by far the largest one I’ve tried so far at 1.4 megs. Do you think there may be a constraint on the size of the data?

The site really should have this URL: http://api.yelp.com /business_review_search?term=pizza&ywsid=9udh9Zd8kh_kqoXmAPaY0g& location=San%20Jose%20CA&num_biz_requested=3

-(void)searchFlickrPhotos:(NSString *)term_param loc:(NSString *)location_param
{
// Build the string to call the Flickr API
NSString *urlString = [NSString stringWithFormat:@"http://api.yelp.com/business_review_search?term=%@&ywsid=%@&location=%@&num_biz_requested=3", term_param, YelpAPIKey, location_param];
NSLog(urlString);
// Create NSURL string from formatted string
NSURL *url = [NSURL URLWithString:urlString];

// Setup and start async download
NSURLRequest *request = [[NSURLRequest alloc] initWithURL: url];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection release];
[request release];

}

My group’s semester project is to create a iphone travel app. My part is getting yelp api to work. I downloaded part 1 & just replaced only the parts I needed with the yelp api. http://www.yelp.com/developers/documentation/search_api#searchHood

However I’m getting the same error as Jared did but I don’t understand his solution.

The site I’m calling is http://api.yelp.com/business_review_search?term=pizza&ywsid=9udh9Zd8kh_kqoXmAPaY0g&location=San2ose庌A&num_biz_requested=3

The errors I get is:
[Session started at 2009-11-30 00:33:39 -0600.]
2009-11-30 00:33:40.848 JSONFlickr[2518:20b] -JSONValue failed. Error trace is: (

)

Here is the method where I know I’m not calling something right. If I NSLog(jsonString), it prints the JSON output but it also puts the errors above in the outputs. Please help.

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

//- (void)connectionDidFinishLoading:(NSURLConnection *)connection;
{
// Store incoming data into a string
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

// Create a dictionary from the JSON string
NSDictionary *results = [jsonString JSONValue];

// Build an array from the dictionary for easy access to each entry
NSArray *categories_info = [[results objectForKey:@"businesses"] objectForKey:@”categories”];

// Loop through each entry in the dictionary…
for (NSDictionary *cate in categories_info)
{
// Get title of the image
NSString *name = [cate objectForKey:@"name"];

debug(@”name: %@”, name);

}

}

Thanks in advance!

Your question is more about Objective-C than the JSON.framework itself. The parser will translate JSON types into Objective-C types in the way described here: http://json-framework.googlecode.com/svn/branches/2.2/documentation/interfaceSBJsonParser.html#_details

You will get a dictionary (or, in some cases, an array) back from the parser. If something is an integer in the JSON text, then you can get its value back like this:

NSNumber tmp = [jsonResult objectForKey:@"farm"];
NSInteger farm = [tmp integerValue];

Or in one line:

NSInteger farm = [[jsonResult objectForKey:@"farm"] integerValue];

int farm = JsonResult.getInteger(@”farm”);

Thanks
