Where JSON_CATEGORY_DATA_URL_STRING
is my feed URL, which returns fine as:
[
{
"group":"For Sale",
"code":"SSSS"
},
{
"group":"For Sale",
"category":"Wanted",
"code":"SWNT"
}
]
I cannot seem to get a nice NSDictionary
(or NSArray
) out of the following code:
+ (NSDictionary *)downloadJSON
{
NSDictionary *json_string;
NSString *dataURL = [NSString stringWithFormat:@"%@", JSON_CATEGORY_DATA_URL_STRING];
NSLog(@"%@",dataURL);
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:dataURL]];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
json_string = [[[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]autorelease];
NSDictionary *json_dict = (NSDictionary *)json_string;
NSLog(@"json_dict\n%@",json_dict);
NSLog(@"json_string\n%@",json_string);
return json_string;
}
I've read many posts on this, but am not getting it.
With IOS5 you can use NSJSONSerialization for serializing the JSON.
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
