iPhone/iOS JSON parsing tutorial [closed]
As a learning experience, I want to make an iPhone application that calls a webserver/webservice, retrieves a JSON response, and uses that response to populate the rows of a UITableView
(assuming it converts the JSON into an NSArray
first).
Anyone know of anything that might be useful?
You will love this framework.
And you will love this tool.
For learning about JSON you might like this resource.
And you'll probably love this tutorial.
As of iOS 5.0 Apple provides the NSJSONSerialization class "to convert JSON to Foundation objects and convert Foundation objects to JSON". No external frameworks to incorporate and according to benchmarks its performance is quite good, significantly better than SBJSON.
SBJSON *parser = [[SBJSON alloc] init];
NSString *url_str=[NSString stringWithFormat:@"Example APi Here"];
url_str = [url_str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURLRequest *request =[NSURLRequest requestWithURL:[NSURL URLWithString:url_str]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response1 encoding:NSUTF8StringEncoding]
NSDictionary *statuses = [parser2 objectWithString:json_string error:nil];
NSArray *news_array=[[statuses3 objectForKey:@"sold_list"] valueForKey:@"list"];
for(NSDictionary *news in news_array)
{
@try {
[title_arr addObject:[news valueForKey:@"gtitle"]]; //values Add to title array
}
@catch (NSException *exception) {
[title_arr addObject:[NSString stringWithFormat:@""]];
}
try out with this fastest JSON framework JSONKit. it's faster than normal JSON framework.
