UITableViewCell unable to dequeue a cell with identifier Cell - must register a nib or a class for the identifier or connect a prototype cell

iOS6之后，按照之前的官方文档会报这样的bug

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'unable to dequeue a cell with identifier Cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard' 

 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"Cell"; 
    [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:CellIdentifier]; 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; 
    if (cell == nil) 
    { 
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; 
          cell.selectionStyle = UITableViewCellSelectionStyleNone; 
    } 
    // config cell
　　...    
   return cell; 
} 

 

添加蓝色部分既可。原因了解并不深入，纯粹是网上的解决方案。
