    <p>I have a NSDictionary that I am trying to get some strings out of. The name of the dictionary is called tweets. I can get the user name and tweet by doing the following.</p> <pre><code> NSDictionary *tweet = self.detailItem; NSString *username = [[tweet objectForKey:@"user"] objectForKey:@"name"]; NSString *tweetText = [tweet objectForKey:@"text"]; </code></pre> <p>If I NSLog the results I get; username is "person's username" and tweetText is "person's tweet." These are both NSString that I can manipulate.</p> <p>However, I also need to get the actual URL from the tweet, not the shortened one. So I have found it in the dictionary with valueForKeyPath. I need this as a string and have tried the following.</p> <pre><code>NSString *url = [tweet valueForKeyPath:@"entities.urls.display_url"]; </code></pre> <p>I can NSLog this as well and I get the proper information. But I think it comes out as an Array? The NSLog looks like this.. url is ( "url goes here" ). With the brackets and quotes. This is not a string like the others. I am assuming it is because of the valueForKeyPath. When I tried to use url hasPrefix, it doesn't like that and mentions you can't have hasPrefix with and array. But I also tried to use multiple objectForKey with entities, urls, and display_url. But this does not work. Is there any way to get my entry into a string format. I have looked over some SO questions and on the web, but can't find anything that is useful for me. Any help will by much appreciated. Thanks for your time</p>

    1. COYou can figure out the type by dumping [url class] to a %@ in an NSLog. Use the debugger with a breakpoint in XCode or Appcode. It will easily reveal the structure of your dictionary.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
