Issues parsing a dictionary

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"]];
