UISearchBar problem with UITableview

[katsogiannis]

Hello all.

i am using the code from iPhone SDK Articles (UITableView ? Indexed table view) and i have some problems with the search function.
i have one view (xib) to each of my rows on the tableview and it works fine. the problem is that when i use the searchbar and i click on the selected row it displays the wrong detilview (xib).
can someone help with this as i am new on xcode.

code below:

- (void)viewDidLoad {
    [super viewDidLoad];
	
	//Initialize the array.
	listOfItems = [[NSMutableArray alloc] init];
	
	NSArray *countriesToLiveInArray = [NSArray arrayWithObjects:@"Austria", @"August", @"Australia", nil];
	NSDictionary *countriesToLiveInDict = [NSDictionary dictionaryWithObject:countriesToLiveInArray forKey:@"Dictionary"];
	
.
.
.
.
.
	
	NSArray *countriesYArray = [NSArray arrayWithObjects:@"YoYo", @"Yes", nil];
	NSDictionary *countriesYDict = [NSDictionary dictionaryWithObject:countriesYArray forKey:@"Dictionary"];
	
	NSArray *countriesZArray = [NSArray arrayWithObjects:@"Zoe", @"Zara", @"Zero", @"", @"", nil];
	NSDictionary *countriesZDict = [NSDictionary dictionaryWithObject:countriesZArray forKey:@"Dictionary"];

	
	[listOfItems addObject:countriesToLiveInDict];
	[listOfItems addObject:countriesLivedInDict];
	.
        .
	[listOfItems addObject:countriesXDict];
	[listOfItems addObject:countriesYDict];
	[listOfItems addObject:countriesZDict];
	
	//Initialize the copy array.
	copyListOfItems = [[NSMutableArray alloc] init];
	
	//Set the title
	self.navigationItem.title = @"Dictionary";
	
	//Add the search bar
	self.tableView.tableHeaderView = searchBar;
	searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
	
	searching = NO;
	letUserSelectRow = YES;
}

Thanks for the quick reply.
Can you bee more specific. i am new on xcode. did you manage to find any problems on the code that i post.
Your help will be very appreciated.

You aren't doing anything different in didSelectRow if you are currently searching.

Oh man you are very very tricky guy.
i had a careful look under my didSelectRowAtIndexPath as you said and it clicked.

i add

if(searching)
cellValue = [copyListOfItems objectAtIndex:indexPath.row];


and problem solved.

Many many thanks....
Brilliant
