title: iOS error: [__NSArrayI objectAtIndex:]: index 1 beyond bounds [0 .. 0]
body: <p>In my application I try to load contents from a url, store them in a mutable array and show them in a table view. But I can't get it working, because every time I run the app this error appears:</p>

  <p>I create the array that should populate the table in my viewDidLoad with:</p>
  
  <pre><code>_videos = [[NSMutableArray alloc] init];
  </code></pre>
  
  <p>Then I connect to the url and parse through the received xml data. This works just like it should. When a certain tag is opened I create my video objects and after filling them with data I add those objects to my array with:</p>
  
  <pre><code>[_videos addObject:currentVideo];
  </code></pre>
  
  <p>This seems to work as well, because it returns the correct number of videos when</p>
  
  <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
  
      return _videos.count;
  }
  </code></pre>
  
  <p>is called. But after this point the app crashes and I don't even reach the point where I try to populate my table view. The function looks like this: </p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  
      Video *curVideo = [_videos objectAtIndex:indexPath.row];
  
      static NSString *CellIdentifier = @"CustomCell";
  
      CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  
      if (cell == nil)        
          cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
  
      cell.titleLabel.text = [curVideo title];
      cell.descLabel.text = [curVideo desc];
  
      return cell;
  }
  </code></pre>
  
  <p>What am doing wrong?</p>
  
  <p>Thanks in advance</p>
