Я пытаюсь получить данные JSON, которые я получу от API веб-службы прямого геокодирования.Формат ответа следующий:
[
{"total":63},{
"t":"1",
"lable":"Gek Poh Shopping Centre",
"address":"762 Jurong West Street 75. (S)640762",

Вот что я сделал.
-(IBAction)search:(id) sender{
self.requestString = [NSString stringWithFormat:@"http://www.streetdirectory.com/api/?mode=search&act=all&profile=sd_default&q=%@&show_additional=0&output=json&limit=1", textField.text];
NSString *escapedString = [self.requestString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
self.request = [NSURLRequest requestWithURL:[NSURL URLWithString:escapedString]];
responseData = [[NSMutableData alloc] init];
rConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[responseData appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary *responseDict = [parser objectWithData:responseData];
NSArray *resultsArray = [responseDict valueForKey:@""]; // am I doing it correctly to get the array?
for (NSDictionary *childDic in resultsArray) {
NSString *str = [childDic objectForKey:@"address"]; // for example I wanna get the address?
label.text = str;
}
}
