extracting information from NSDictionary - objective-c

Question

I have a NSDictionary response from a Flickr api request and it's description looks like this:
self.userInfo: {
"_text" = "\n\n";
person = {
"_text" = "\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n";
description = {
};
iconfarm = 0;
iconserver = 0;
id = "83943196#N02";
ispro = 0;
location = {
};
"mbox_sha1sum" = {
"_text" = 7b61c5d24f12345678be82c31234567830540;
};
mobileurl = {
"_text" = "http://m.flickr.com/photostream.gne?id=12345678";
};
nsid = "12345678#N02";
"path_alias" = "";
photos = {
"_text" = "\n\t\t\n\t\t\n\t\t\n\t\t\n\t";
count = {
"_text" = 2;
};
firstdate = {
"_text" = 12345678;
};
firstdatetaken = {
"_text" = "2012-08-01 12:46:38";
};
views = {
"_text" = 0;
};
};
photosurl = {
"_text" = "http://www.flickr.com/photos/12345678#N02/";
};
profileurl = {
"_text" = "http://www.flickr.com/people/12345678#N02/";
};
realname = {
"_text" = "Me TheUser";
};
timezone = {
label = "Pacific Time (US & Canada); Tijuana";
offset = "-08:00";
};
username = {
"_text" = metheuser;
};
};
stat = ok;
}
I'm having truoble figuring out how to extract the realname value into a NSString.
I've tried:
NSString * temp = [self.userInfo valueForKey:#"realname"];
NSLog (#"FL: nameOfSignedInUser. nameself.userInfo: %#", temp.debugDescription);
but that comes back as nil.
thank you!

Answer 1

NSString *name = [self.userInfo valueForKeyPath:#"person.realname._text"];

Answer 2

NSString *realName = [[[self.userInfo objectForKey:#"person"] objectForKey:#"realname"] objectForKey:#"_text"];
