Problem with didSelectRowAtIndexPath with Indexed TableView

[Sentis]

Hi all,

I have an app with a regular TableView. When the user selects a cell, another view is brought up, that has the content of the cell as the navigationItem.Title

That worked fine.

When I tried to make the TableView into an indexed tableView the variable failed to carry through.

Here is the indexedTableView code:

- (void)viewDidLoad {

	self.navigationItem.title = @"Glossary";


	
	IndexItems = [[NSMutableArray alloc] init];
	
	
	[IndexItems addObject:@"Alpha"];
	[IndexItems addObject:@"Beta"];
	[IndexItems addObject:@"Charlie"];
	[IndexItems addObject:@"Delta"];
	[IndexItems addObject:@"Echo"];
	wordIndex = [[NSMutableArray alloc] init];
    
    for (int i=0; i<[IndexItems count]-1; i++){
        //---get the first char of each word---
        char alphabet = [[IndexItems objectAtIndex:i] characterAtIndex:0];
        NSString *uniChar = [NSString stringWithFormat:@"%C", alphabet];
        
        //---add each letter to the index array---
        if (![wordIndex containsObject:uniChar])
        {            
            [wordIndex addObject:uniChar];
        }        
    }	
	
	[super viewDidLoad];
}



- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning]; 
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
	

	return 1;
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
		
	return [wordIndex objectAtIndex:section];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
		//---get the letter in each section; e.g., A, B, C, etc.---
		NSString *alphabet = [wordIndex objectAtIndex:section];
		
		//---get all words beginning with the letter---
		NSPredicate *predicate = 
        [NSPredicate predicateWithFormat:@"SELF beginswith[c] %@", alphabet];
		NSArray *items = [IndexItems filteredArrayUsingPredicate:predicate];
		
		//---return the number of words beginning with the letter---
		return [items count];    
		
	}
	





- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
		return wordIndex;

}



- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	
    static NSString *CellIdentifier = @"Cell";
    
	UITableViewCell *cell = 
	[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] 
				 initWithStyle:UITableViewCellStyleDefault 
				 reuseIdentifier:CellIdentifier] autorelease];
	}
	
	NSString *alphabet = [wordIndex objectAtIndex:[indexPath section]];
	NSPredicate *predicate = 
	[NSPredicate predicateWithFormat:@"SELF beginswith[c] %@", alphabet];
    NSArray *items= [IndexItems filteredArrayUsingPredicate:predicate];
    
	if ([items count]>0) {
        NSString *cellValue = [items objectAtIndex:indexPath.row];
        cell.textLabel.text = cellValue;
	}
	
	return cell;
}



- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
	
	NSString *selectedItem = [IndexItems objectAtIndex:indexPath.row];
	
	
	//Initialize the detail view controller and display it.
	DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];
	dvController.selectedItem = selectedItem;
	[self.navigationController pushViewController:dvController animated:YES];
	[dvController release];
	dvController = nil;	

}
- (void)dealloc {
	
	[IndexItems release];
	[wordIndex release];
    [super dealloc];
}

Thanks So much in advance!!

The presence of an index should have zero effect on didSelectRow. You are doing something else wrong.

I do notice that you have only 1 section, and that sort of defeats the purpose of having an index.

You might also want to look at the various substring options, as that would keep you from having to switch between chars and NSStrings.
