I tried to download this geocode data

Question

Basically I am accessing this URL

http://maps.googleapis.com/maps/api/geocode/json?address=sudirman&sensor=true&bounds=-7.186696,105.7727|-5.186696,107.7727

However, the result is empty. Even though it should show something. I used objective-c

With this code:

response= [NSURLConnection sendSynchronousRequest:request returningResponse:&urlresponse error:&error];

json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];

I think the | need to be urlencoded. How to do so?

Answer 1

[NSURLConnection sendSynchronousRequest:request returningResponse:&urlresponse error:&error];

returns NSData, which when serialised will produce JSON, so you need to do:

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingAllowFragments error:&error];

to get the JSON.
