    copied!<p>please help me with this problem. I cannot find any problem for the last 4 days and nights. This is the simple job that I already did in another project. But the different thing is that this is my first time to use UISearchBar with Display Controller. Anyway here are my codes.</p> <p>mnuSearch.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import "constants.h" #import "JSON.h" #import "Initial.h" @interface mnuSearch : UIViewController&lt;UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate, UISearchDisplayDelegate&gt; { } @property (retain) NSMutableArray *_arrSearchNews; @property (nonatomic, retain) IBOutlet UISearchBar *txtSearchBox; @property (nonatomic, retain) IBOutlet UITableView *tblNewsSearch; @end </code></pre> <p>mnuSearch.m</p> <pre><code>#import "mnuSearch.h" @interface mnuSearch () @end @implementation mnuSearch @synthesize _arrSearchNews; @synthesize txtSearchBox, tblNewsSearch; #pragma mark - When "search button" in keyboard is clicked - (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar { [searchBar setShowsCancelButton:NO animated:YES]; [searchBar resignFirstResponder]; [self searchNews:searchBar.text]; [self.tblNewsSearch reloadData]; } #pragma mark - Search news -(void)searchNews:(NSString*)query { // Retrieve searched news list NSString *url = [NSString stringWithFormat:@"http://mydomain.com/NewsSearch.ashx?a=%@&amp;b=%@&amp;c=%@", currentLocale, uniqueID, [Initial getUrlEncode:query]]; NSURLRequest *_rqJsonDataList = [NSURLRequest requestWithURL:[NSURL URLWithString:url]]; NSData *_rpJsonDataList = [NSURLConnection sendSynchronousRequest:_rqJsonDataList returningResponse:nil error:nil]; NSString *_strJsonDataList = [[NSString alloc] initWithData:_rpJsonDataList encoding:NSUTF8StringEncoding]; NSDictionary *_nsDicJsonDataList = [_strJsonDataList JSONValue]; NSString *_strStatusCode = [_nsDicJsonDataList objectForKey:@"StatusCode"]; NSString *_strStatusMessage = [_nsDicJsonDataList objectForKey:@"StatusMessage"]; // OK if ([_strStatusCode isEqualToString:@"OK"]) { NSArray *_arrList = [_nsDicJsonDataList objectForKey:@"Table1"]; [self._arrSearchNews removeAllObjects]; [self._arrSearchNews addObjectsFromArray:_arrList]; } // Error else { UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:_strStatusMessage delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK",nil]; [alert show]; } } #pragma mark - [UITableView] Number of Sections - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } #pragma mark - [UITableView] Number of Rows In Section - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { int _retValue = 0; _retValue = [_arrSearchNews count]; return _retValue; } #pragma mark - [UITableView] Return table view cell - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellIdentifier = @"mnuSearchCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellIdentifier]; } // Set font UIFont *textLabelFont = [UIFont fontWithName:@"Helvetica" size:14]; cell.textLabel.font = textLabelFont; UIFont *detailTextLabelFont = [UIFont fontWithName:@"Helvetica" size:12]; cell.detailTextLabel.font = detailTextLabelFont; cell.imageView.image = nil; NSDictionary *_nsDic = [self._arrSearchNews objectAtIndex:indexPath.row]; NSString *abc = [NSString stringWithFormat:@"[%@] %@", [_nsDic objectForKey:@"GUBUN_NM"], [_nsDic objectForKey:@"TSUBJECT"]]; NSLog(@"%@", abc); **//--&gt; This returns text I wanted.** cell.textLabel.text = [NSString stringWithFormat:@"[%@] %@", [_nsDic objectForKey:@"GUBUN_NM"], [_nsDic objectForKey:@"TSUBJECT"]]; cell.detailTextLabel.text = nil; return cell; } - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization } return self; } - (void)viewDidLoad { [super viewDidLoad]; self._arrSearchNews = [[NSMutableArray alloc] init]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (void)viewDidUnload { [self setTblNewsSearch:nil]; [self setTxtSearchBox:nil]; [super viewDidUnload]; } @end </code></pre> <p>I really don't understand why my UITableView does not return any data. When I type in some keywords in Search Box, it shows me "No Results". And when I click "Search" in keyboard, my app gets data from json. "_arrSearchNews" has got 340 objects. But UITableView still remains with "No Results". Please help me with this error. Thanks in advance.</p>
