I have the following json:
http://www.adityaherlambang.me/webservice.php?user=2&num=10&format=json
I would like to get all the name in this data by the following code, but it gives an error. How can I fix it?
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
NSDictionary *results = [responseString JSONValue];
NSDictionary *users = [results objectForKey:@"users"] objectForKey:@"user"];
for (NSDictionary *user in users){
//NSLog(@"key:%@, value:%@", user, [user objectForKey:user]);
NSString *title = [users objectForKey:@"NAME"];
NSLog(@"%@", title);
}
Error:
