AppDelegate의 NSURLConnection 및 SBJSon

Question

저는 ARC 및 스토리 보드 (iOS 5)를 사용하는 xCode 4.2에 있습니다. 내 TableViewController에 짹짹을 넣으려고합니다. 내 NSURLConnection을 배치하면 모든 것이 잘되고 대리자의 트윗 (NSArray)에 응답이 이미 있습니다. 문제는 테이블 뷰를 채우지 않는다는 것입니다. 받은 데이터에 대해 SBJson을 사용하고 있습니다. 내가 놓친 게 있니?

AppDelegate.m

#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}&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 

이 내 테이블 뷰 컨트롤러에서 위임 방법이다.

- (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; 
} 

정말 조언이 필요합니다.
