我正在使用Apple Developer Tutorial并尝试重新加载我点击的行。行没有重新加载。我试图在[beginUpdate]之间包装reloadRows命令;和[endUpdate];语句,但它仍然没有重新加载行。任何信息/帮助? (显然,我是客观c的新手。)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"ListPrototypeCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
ToDoItem *toDoItem = [self.toDoItems objectAtIndex:indexPath.row];
cell.textLabel.text = toDoItem.itemName;
if (toDoItem.completed)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:NO];
ToDoItem *tappedItem = [self.toDoItems objectAtIndex:indexPath.row];
tappedItem.itemName = @"YouTappedThis";
tappedItem.completed = !tappedItem.completed;
[tableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationNone];
}
