Parse JSON in Objective-C with SBJSON

I just want to parse this JSON string in Objective-C using the SBJSON framework, and retrieve the three units of data:

{"x":"197","y":"191","text":"this is a string"}

How can this be done?

Here's an example:

NSString *jsonText = @"...";
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary *dict = [parser objectWithString:jsonText];
for (NSString *key in [@"x y text" componentsSeparatedByString:@" "]) {
  NSLog(@"%@ => %@", key, [dict objectForKey]); 
}

Here's something similar for SBJson4Parser:

id parser = [SBJson4Parser parserWithBlock:^(id v, BOOL *stop) {
    for (NSString *key in [@"x y text" componentsSeparatedByString:@" "]) {
        NSLog(@"%@ => %@", key, [v objectForKey]); 
    }
}
allowMultiRoot:NO
unwrapRootArray:NO
errorHandler:^(NSError *err) {
    // handle error here                                 
}];

NSString *jsonText = @"...";
[parser parse: [jsonText UTF8String]];

NSString * jsonString = @"{\"x\":\"197\",\"y\":\"191\",\"text\":\"this is a string\"}";
SBJSON *jsonParser = [[SBJSON alloc] init];
NSDictionary * dictionary = [jsonParser objectWithString:jsonString];
NSLog(@"x is %@",[dictionary objectForKey:@"x"]);
[jsonParser release];
