UITableView cellForRowAtIndexPath is not called

Question

It's table view using UISearchBar and UITableView . numberOfRowsInSection called. but cellForRowAtIndexPath is not being called. I don't understand why cellForRowAtIndexPath is not called.

RegistMovieViewController.h

#import <UIKit/UIKit.h>

@interface RegistMovieViewController : UIViewController <UISearchBarDelegate, UITableViewDataSource, UITableViewDelegate>
{
    UITableView *searchResultView;
    NSMutableArray *searchResult;
}

@end

RegistMovieViewController.m

//
//  RegistMovieViewController.m
//

#import "RegistMovieViewController.h"
#import <TBXML.h>
#import <TBXML+HTTP.h>
#import <TBXML+NSDictionary.h>

@interface RegistMovieViewController ()

@end

You have to also implement

-tableView:numberOfRowsInSection:

So UITableView can determine how often it has to call -tableView:cellForRowAtIndexPath: .
