"*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]'"

I know this is a common question on Stack Overflow, but unfortunately none have been able to lead me to my solution.

I'm trying to list the files in my documents directory in a UITableView. (I also have another tableview displaying devices I'm connected to)

I know I'm getting this error because its saying that my array has 0 objects, and I'm trying to access the object at index 1.

But I have a file in my documents directory. If I have 2 files, when I delete 1, I get this error. When the app is relaunched, it shows the UITableView correctly with the file deleted.

I got my code from here: Objective-C: How to list files from documents directory into a UITableView?

this is my content:

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    if (tableView == _tblConnectedDevices){
    return [_arrConnectedDevices count];
    }
    if ([filePathsArray count] > 0){
        return [filePathsArray count];
    }
    else 
    return 1;
}


-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    if (tableView == _tblConnectedDevices){
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"CellIdentifier"];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellIdentifier"];
    }

    cell.textLabel.text = [_arrConnectedDevices objectAtIndex:indexPath.row];

    return cell;
    } else {
        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell" forIndexPath:indexPath];
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  error:nil];
        NSString *last = [documentsDirectory stringByAppendingPathComponent:[filePathsArray objectAtIndex:indexPath.row]];
        NSString *last2 = [[last lastPathComponent] stringByDeletingPathExtension];
        cell.textLabel.text = last2;
        return cell;
    }
}

My delete void:

-(IBAction)deleteFile:(id)sender{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                         NSUserDomainMask,
                                                         YES);
    NSString *fullPath = [[paths lastObject] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.txt", fileName]];
    NSError *error;
        [[NSFileManager defaultManager] removeItemAtPath:fullPath error:&error];
    [_cellView reloadData];
}
Solution

  • Reload your filePathArray in deleteFile: Also set breakpoint and look how many files you have in array
