Question

I’m making an iOS that lists the files in the Documents dictionary. I want to display this data in a UITableView, the problem is that it’s not working.
It loads the data in to the view. Then the application freezes and calls EXC_BAD_ACCESS
This is my code:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    timesRun = 0;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectoryPath = [paths objectAtIndex:0];
    NSString *bundleRoot = [[NSBundle mainBundle] bundlePath];
    dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectoryPath error:nil];
    [bundleRoot release];
    NSLog(@"Count: %i",[dirContents count]);
    return [dirContents count];
}

- (UITableViewCell *)tableView:(UITableView *)tableViewData cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = nil;
    int Locatation = indexPath.row;
    Locatation++;
    cell = [tableViewData dequeueReusableCellWithIdentifier:@"MyCells"];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"MyCell"]autorelease];
    }
    //cell.textLabel.text = [NSString stringWithFormat:@"Cell: %i",Locatation];
    cell.textLabel.text = [dirContents objectAtIndex:timesRun];
    timesRun++;  
    return cell;
    NSLog(@"Did return");
}
- (void)tableView:(UITableView *)tableViewDat didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    NSLog(@"%@",cell.textLabel.text);
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

My problem was sort of like Mario’s answer. [dirContents count] returned a higher value than the amount of times it could add an object from the array.

In other words it was a Out of Bounds error.
