Issues parsing a dictionary - ios

Question

Below is a dictionary I have created by retrieving the my twitter statuses for an App Only twitter feed. I have parsed and returned the value of "text" successfully, and displayed it in a table view cell as follows:
static NSString *cellID = #"FeedCell3" ;
FeedCell3 *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {
cell = [[FeedCell3 alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
NSInteger idx = indexPath.row;
NSDictionary *t = self.twitterDataSource[idx];
cell.updateLabel.text = t[#"text"];
return cell;
However, when I try to return other values for keys such as "profile_image_url" and "screen_name" using the method below, an (null) is returned, even though there is a value in the dictionary. What am I doing wrong?
cell.nameLabel.text = t[#"screen_name"];
NSURL *profileImageURL = t[#"profile_image_url"];
NSLog(#"%#", profileImageURL);

Answer 1

Those latter two keys you're going for are in the user dictionary, so try
t[#"user"][#"screen_name"];
t[#"user"][#"profile_image_url"];
The second issue will appear when you solve the first. The url is a string. To get a proper NSURL you'll need to use an NSURL class method.
NSURL *aURL = [NSURL URLWithString:t[#"user"][#"profile_image_url"]];
