Answer 1

Implement SBJson .

Load json response into NSDictionary:

NSDictionary *myDictionary = [myJsonString JSONValue];

Then read from dictionary like:

NSString *idString = [myDictionary objectForKey:@"id"];

Answer 2

You just need to parse it, luckily there are a number of ways to do so easily in iPhone. You can use this framework for instance: JSON framework

Answer 3

Try that:

- (void)request:(FBRequest *)request didLoad:(id)result {
    NSString *jsonString = [NSString stringWithString:[result JSONRepresentation]];
    NSDictionary *userDict = [jsonString JSONValue];
    // do something with the values in the dictionary...
}
