剛接觸iOS，依照教程操作執行出現錯誤

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

解決的方法是加一句：

[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:CellIdentifier];

加的位置是：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"ListPrototypeCell";
[self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:CellIdentifier];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

// config cell
　XYZToDoItem * toDoItem = [self.toDoItem objectAtIndex:indexPath.row];

cell.textLabel.text = toDoItem.itemName;

return cell;
}
