How to integrate Google places Api into our application? - iphone

Question

iam developing one application.In that i want to use the google places api.I written the url and established the connection like
NSURL *URL = [NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&radius=500&types=food&name=harbour&sensor=true&key=AIzaSyDbiWWIOmc08YSb9DAkdyTWXh_PirVuXpM"];
NSURLRequest *request=[[NSURLRequest alloc]initWithURL:URL];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
But in did finish loading delegate method i cant get the data.That code is here.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[connection release];
NSString *responseString = [[NSString alloc]initWithData:responseDataencoding:NSUTF8StringEncoding];
[responseData release];
SBJSON *parser = [[SBJSON alloc]init];
NSDictionary *data = (NSDictionary *) [parser objectWithString:responseString error:nil];
}
So please tell me where i did the mistake.Why iam not getting the data.

Answer 1

Use ASIHTTPRequest framwork all these problems are automatically handle
all you have to do is just create a url
and parse the response using JSON framework

According to my knowledge there are few mistaks.
NSString *responseString = [[NSString alloc]initWithData:responseDataencoding:NSUTF8StringEncoding];
The words responseData encoding are two world. I don't know whether you have pasted like that.
And I hope you have used -(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data delegates to append data to responseData object.
I think you do not need to cast to NSDictionary. You can use following code.
NSString *content = [[NSString alloc] initWithBytes:[responseDate bytes] length:[responseDate length] encoding:NSUTF8StringEncoding];
NSLog(#"Data = %#", content);
NSError *error;
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary *jsonD = [parser objectWithString:content error:&error];
