#interface ViewController ()
{
NSMutableData *webData;
NSURLConnection *connection;
NSMutableArray *moviesArray;
}
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[[self myTableView]setDelegate:self];
[[self myTableView]setDataSource:self];
moviesArray=[[NSMutableArray alloc]init];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
[webData setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
[webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
NSLog(#"Fail");
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
NSDictionary *allDataDictionary=[NSJSONSerialization JSONObjectWithData:webData options:0 error:nil];
NSDictionary *response=[allDataDictionary objectForKey:#"response"];
NSDictionary *hotProgram=[response objectForKey:#"hot_program"];
NSArray *itemPageHot=[hotProgram objectForKey:#"page"];
for (NSDictionary*dic in itemPageHot) {
NSString *text1=[dic objectForKey:#"text1"];
[moviesArray addObject:text1];
}
[[self myTableView]reloadData];
}
- (IBAction)getData:(id)sender {
NSURL *url=[NSURL URLWithString:#"http://vmg.hdvietpro.com/ztv/home"];
NSURLRequest *request=[NSURLRequest requestWithURL:url];
connection = [NSURLConnection connectionWithRequest:request delegate:self];
if(connection){
webData =[[NSMutableData alloc]init];
NSLog(#"ket noi thanh cong");
}
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return [moviesArray count];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString*CellIndentifier=#"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:CellIndentifier];
if(!cell){
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIndentifier];
}
cell.textLabel.text=[moviesArray objectAtIndex:indexPath.row];
return cell;
}

You're not traversing the dictionary correctly. The key page is a child of key itemPage so this should work
NSArray *itemPageHot = [[hotProgram objectForKey:#"itemPage"] objectForKey:#"page"];
I'd recommend downloading a JSON inspector for issues like this. VisualJSON in the app store is what I use.
