Custom UITableViewCells Alloc Problrm

Question

So I have custom UITableViewCells (made with storyboard), and when I do not literally alloc, init the cells, the app crashes. However, since they are custom cells, I don't know how to alloc/init them.

This code crashes:

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

    TableViewCells *cell = (TableViewCells *)[tableView dequeueReusableCellWithIdentifier:@"TableViewCellsID"];

return cell;
}

with this printed to the console:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', 
reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'

I understand this means its crashing because there is no cell allocated yet, however when I try to allocate it, I have to specify a cell style.

So, when I build the cell as follows, it doesn't crash:

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

     TableViewCells *cell = (TableViewCells *)[tableView  dequeueReusableCellWithIdentifier:@"TableViewCellsID"];
     if (cell == nil)
          cell = [[TableViewCells alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"TableViewCellsID"];

     return cell;
}

The problem is the code that works (the second set), requires me to set a UITableViewStyle. And as far as I know, there is no UITableViewStyleCustom.

Any helps would be appreciated.

It crashes in first case because there is no cell to reuse, and you are calling dequeueReusableCellWithIdentifier.

EDIT - For custom cell initialisation you can check following threads -
