Body
<p>I know the question is old, but in support of the above answers i wanted to share my working code. Just add these two methods to whatever class.The code checks if facebook app is installed, if not installed the url is opened in a browser.And if any errors occur when trying to find the profileId, the page will be opened in a browser. Just pass the url(example, <a href="http://www.facebook.com/AlibabaUS" rel="noreferrer">http://www.facebook.com/AlibabaUS</a>) to openUrl: and it will do all the magic. Hope it helps someone!.</p> <blockquote> <p>NOTE: UrlUtils was the class that had the code for me, you might have to change it to something else to suite your needs.</p> </blockquote> <pre><code>+(void) openUrlInBrowser:(NSString *) url { if (url.length > 0) { NSURL *linkUrl = [NSURL URLWithString:url]; [[UIApplication sharedApplication] openURL:linkUrl]; } } +(void) openUrl:(NSString *) urlString { //check if facebook app exists if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://"]]) { // Facebook app installed NSArray *tokens = [urlString componentsSeparatedByString:@"/"]; NSString *profileName = [tokens lastObject]; //call graph api NSURL *apiUrl = [NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/%@",profileName]]; NSData *apiResponse = [NSData dataWithContentsOfURL:apiUrl]; NSError *error = nil; NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:apiResponse options:NSJSONReadingMutableContainers error:&error]; //check for parse error if (error == nil) { NSString *profileId = [jsonDict objectForKey:@"id"]; if (profileId.length > 0) {//make sure id key is actually available NSURL *fbUrl = [NSURL URLWithString:[NSString stringWithFormat:@"fb://profile/%@",profileId]]; [[UIApplication sharedApplication] openURL:fbUrl]; } else{ [UrlUtils openUrlInBrowser:urlString]; } } else{//parse error occured [UrlUtils openUrlInBrowser:urlString]; } } else{//facebook app not installed [UrlUtils openUrlInBrowser:urlString]; } } </code></pre>

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.
