    <p>I'm in xCode 4.2 using ARC and Storyboard (iOS 5). I suppose to put Tweets to my TableViewController. As I placed my NSURLConnection, everything goes fine and I have the response already in tweets(NSArray) in the delegate. The problem is it doesn't populate the table view. I am using SBJson for the received data. Am I missing something?</p> <p>AppDelegate.m</p> <pre><code>#import "AppDelegate.h" #import "TwitterViewController.h" #import "SBJson.h" @implementation AppDelegate @synthesize window = _window; @synthesize receivedData; @synthesize tableViewController; @synthesize tweets; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { tweets = [NSMutableArray array]; NSURLRequest *request = [NSURLRequest requestWithURL: [NSURL URLWithString:@"http://search.twitter.com/search.json?q={username}&amp;rpp=5"]]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES]; if (theConnection) { receivedData = [NSMutableData data]; } return YES; } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [receivedData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [receivedData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"Connection failed! Error - %@ %@", [error localizedDescription], [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]); } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"Succeeded! Received %d bytes of data",[receivedData length]); NSString *responseString = [[NSString alloc] initWithData:receivedData encoding:NSUTF8StringEncoding]; NSDictionary *results = [responseString JSONValue]; NSArray *allTweets = [results objectForKey:@"results"]; [tableViewController setTweets:allTweets]; } @end </code></pre> <p>This is the delegate methods in my table view controller.</p> <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [tweets count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"twitter"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } NSDictionary *aTweet = [tweets objectAtIndex:[indexPath row]]; NSString *textFrom = [aTweet objectForKey:@"text"]; cell.textLabel.text = textFrom; return cell; } </code></pre> <p>I really need some advice.</p>

Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
